A novel stereo robot vision system using a double-ply liquid crystal display (LCD) is proposed. The images of an object from right and left CCD cameras are displayed on the double-ply LCD. The light intensity transmitted through the double-ply LCD depends on the degree of matching between the images of two cameras. Therefore, the distance from the camera to the object can be deduced form the transmitted light intensity without using sophisticated computer algorithm.

Providing supports to the human worker based on his intention can effectively increase assembly efficiency while reduce worker's load. Human intention can be judged through human gestures easily. Due to the worker's assembly characteristics and the assembly environment, it is difficult to use cameras to recognize human gesture only detecting on the skin color. In this paper, a template-based gesture recognition method is proposed to recognize human gestures. The results show that using this method, human gestures can be recognized easily and the success rate is high.

We propose a method for generating a 3D model with entire shape and proper color information of a real-world object using range intensity images. Texture mapping is effective for 3D modeling. However, there are some problems of reconstructing correct object color and generating omnidirectional geometric model. In this paper, we construct a system of integrated processing of multiple range and range intensity images, correction of color images and registration of geometric model and color images. The effectiveness of the proposed method is shown by experiments, and a 3D model with entire shape and color information is created.

Tandem low coherence interferometer with optical fiber is useful for remote calibration of the length treatable to national standards, but it required broad spectral light source for precision calibrations. Excess fractions method is applied to the tandem interferometer with non-broad spectral light sources because the optical path difference of each interferometer can be longer than the coherence length of the light source used. Therefore, this method may be applied to the remote calibration using a general fiber net works and light sources.

We have proposed a three-axis displacement sensor which can detect displacements in the in-plane direction and normal line direction simultaneously. Displacements can be obtained by analyzing interference signals generated by diffracted beams from two grating. In this report, a pitch of the grating is shortened from 10 μm to 1.6 μm. As result, resolution is improved from 5 nm to 1 nm and linearity error within one signal period in the in-plane direction is reduced from ±100 nm to ±15 nm.

In recent years, the CMM (Coordinate Measuring Machine) quickly has been spreading in the manufacturing industry. With this phenomenon, the environmental condition and installation site of CMMs has been changed from the temperature control room to the workshop environment and the production line without air conditioning. However, even in severe environment the demand to high accuracy measurements by CMM has been enhancing still more. Therefore, the methods to evaluate and realize the high accuracy measurements by CMM in workshop environment have been investigated. In this paper, we propose the evaluation and correction method of temperature measurement error.

Precision line scales are widely used for calibration of measuring instruments. A one-dimensional calibration system for line scales has been developed. The calibration system, SSC-05, consists of a moving microscope that detects the graduations on the line scale under test. The laser source for the interferometer systems of SSC-05 is calibrated in real time by an iodine stabilized He-Ne laser. In this report, uncertainty factors resulting from optical systems are discussed after briefly introducing the calibration system.

As demands for areal surface texture measurement increase, various types of areal surface texture measuring instruments are developed. However, the equivalences of measured data among different measuring principle do not hold, thereby the necessity of standards is discussed to calibration and verification of areal surface texture measuring instruments. In this study, areal roughness standards for the areal surface texture measurements are machined by an ultra-precision machine and then their replicas are developed. The areal roughness standards need irregular surface textures to verify the inherent characteristics on areal surface texture measuring instruments. The irregular surface texture data were generated by use of the non-causal 2D auto-regressive stochastic model. The roughness standards are measured by areal surface texture measuring instruments and the measured data are compared with the generated data.

In order to optimize shapes and materials of a near-field optical probe, we analyzed electromagnetic fields around two sub-wavelength apertures in a metallic thin film on a tip of optical probe using our three dimensional (3D) numerical simulation program based on the boundary element method (BEM). As the result, it was recognized that, depending on dimensions of apertures and metals of films, amplitudes of electromagnetic near-field fields around two apertures were considerably different. Selecting a suitable shape of Ag film for normal incident light with 488nm wavelength, the electric field was intense around the bottom ends of apertures.

Since we are researching in the direct measurement of the spindle error motion using the regular crystalline lattice and the scanning tunneling microscope (STM), the two-dimensional displacement measurement with a resolution of sub-nanometer or less is required. In a previous research, we proposed the two-dimensional displacement measurement method with 10-picometer resolution using a combination of the STM and the highly oriented pyrolytic graphite (HOPG) crystal. However, it is difficult to design and use due to the method needs two STM tips. In this article, therefore, the new measurement method with only one STM tip based on the multi-tunneling-probe STM technique is proposed. From the experimental result, this new method shows a capability of the displacement measurement with sub-nanometer or several 10 picometer resolution.

Diamond turning with fast tool control (FTC) is implemented for fabrication of optical components including micro-lens array. With the increase of fabrication area of micro-lens array, it is important to monitor the long time fabrication process influenced by tool damage, tool wear, etc. Micro cutting tool wear is the reason to reduce both surface finish and accuracy of the micro-lens array. This paper presents experimental results of detection of micro cutting tool wear by FTC-unit integrated with a sensitive piezoelectric force sensor, which is designed for in-process measuring the cutting force.

Second differences of straightness were analytically derived from measurements by applying restriction conditions estimated from behavior of measurements to measurement model using 3 point method with zero adjustment method. By obtaining straightness from them, influences of fluctuations in calibrated zero differences were reduced comparing to the conventional method correcting by statistically averaged values. Performances of the straightness measurement system were evaluated by comparing straightness derived from measurements using 2 kinds of integrated 3 point methods and 3 kinds of inverse methods.

This paper describes the measuring method of the straightness for 2-D stage. The position of 2-D stage which has two straight edges in X and Y-direction is measured by laser interferometer. This measuring result includes two kinds of errors which are motion errors of the stage and profile errors of the reference mirrors. Multi-point method is generally used in measuring straightness. However, multi-point method includes zero-adjustment errors. So we proposed the new method that a single probe was used for each axis measurement. It isn't necessary to consider zero-adjustment errors in the proposed method. We present the result applying our proposed method to the low vibration stage in this paper.

The purpose of this study is to make an investigation into the effects of cutting fluid on tool wear in high-speed end-milling of titanium alloy. Cutting tests were carried out to observe state of chips on cutting edge and to measure width of tool wear land and dynamic cutting forces by 4 meter length of cut under some conditions: that is, in dry, with air blow, and with mist of cutting fluid. As a result, it was revealed that tool wear in up-cut was smaller with mist than in dry, however, tool wear in down-cut was larger.
