1P1-F08 Development of micro displacement visualization sticker that achieves measurement of 1 micrometer(Non-contact Sensing)

Abstract

This paper proposes a micro displacement visualization sticker using a moire fringe which can display characters and fringe that correspond to a magnitude of displacement without the use of electronic elements, such as amplifiers, strain gauges and wires. The sticker is simply attached to a measurement object, and it shows displacement information by characters which can be visible to the naked eye. Accurate numerical value of the displacement can be obtained from an image of the sticker by using image processing. The structure of the sticker is simple and its fabrication is inexpensive. The results show that the sticker provides the displacement information by characters and accurate numerical value of the displacement using image processing.
