A negative image is not, in general, reconstructed from a hologram. This paper reports that a negative image has, however, been reconstructed from both a direct transmission hologram and an image hologram produced under such particular conditions that the signal beam is more intense than the reference beam and that the photographic film is overexposed. The negative image reconstructed from an image hologram is better in quality than that reconstructed from a direct transmission hologram. These reconstructed images are not completely negative; the degree of completeness depends on both the intensity ratio of signal beam to reference beam and the extent of overexposure. Such negative image reconstructions in holography apparently resemble the solarization or the Sabattier effect in conventional photography.

The distinct differences in the field-evaporation end form of W, Ta, Mo and Nb are investigated by comparing the temperature dependence of their polarization energy and binding energy. At low temperatures the field-evaporation end form is mainly influenced by the polarization energy of the atom under a strong electric field. The influence decreases in the order Ta>Nb>W>Mo. As the field-evaporation temperature is raised the influence is gradually transferred from polarization energy to binding energy. Excepting the {001} planes the binding energy obtained from the Morse potential energy are in fair agreement with the experimental results. The field-evaporation end forms at high temperatures are mainly influenced by the magnitude of the activation energy due to the self migration of the atoms on the surface of each crystal plane. The influence of the residual gases, the change of field-evaporation mechanism and the anisotropy of elastic deformation are also described.

The fifth- and seventh-order aberrations are considered in the general case where an object point is not necessary coplanar with a reference and an illuminating light source. As an interesting case, the aberration free system for a particular point object as described in the previous paper [Oyo Buturi 37 (1968) 518] is chosen and the following results are obtained. It is found that the aberrations of the holographic imaging system is dominated by those of the third-order. Further it is found that field aperture becomes constant and flatness of field is improved and asymmetricity of field disappers as working distance increases. The maximum field aperture is obtained when a primary object is located on z-axis.

A piezoelectric rapid scanning Fabry-Perot interferometer was constructed, from which up to twelve portions of the spectrum were electronically sampled and displayed on a CRT screen. With a power input of 1.5 watts to the vibrator having a resonant frequency of 27.5kHz, the peak-to-peak amplitude of oscillation of the etalon plate was 3.2μ and ten orders of the spectrum were scanned per half-period (that is, in 18μ sec). The amount of bending of the oscillating etalon plate measured by an interferometric method agrees, within experimental error, with the values calculated by treating the plate as a thin plate. The dynamic finesse of the whole system decreased to 10.5 at the scanning speed of 3μ sec/free spectral range when the central part of the plate of diameter 7mm was used, as compared with the static finesse of 17. The relation between the finesse of the system and the scanning speed was measured and compared with the calculated bending of the etalon plate. Taking account of the effect of inclination of the etalon plate due to deviation of the center of gravity of the plate from the axis of the piezoelectric vibrator, a closer agreement between the experimental and calculated results is obtained. An electronic circuit for data representation was constructed which extracts only desired linearly scanned portions from the whole scanned photodetector output and represents them in successive time intervals on different parts of the CRT screen.
