Abstract: A signal image is transmitted by write light from a transmission type liquid crystal element 4 to an optically-addressed type parallel-aligned nematic-liquid-crystal spatial light modulator 6. The numerical aperture NAL of a relay lens 5, the pitch P of the pixel structure of the transmission type liquid crystal element 4, and the wavelength &lgr; of light from the write light source 1 are set with the condition 1/2P<NAL/&lgr;<1/P. As a result, the signal component caused by the pixel structure can be erased. Furthermore, no degradation is generated in the entire range of the spatial frequencies of the signal image that can be produced by the transmission type liquid crystal element 4.

The transfer aid mechanism according to the invention includes casters disposed at four locations on a frame, and a drive mechanism which is elevatable with respect to the frame. When required, the drive mechanism is lowered to bring its drive wheel into contact with a floor, and when the drive wheel is driven for rotation under this condition, the transfer aid mechanism may be moved back and forth by utilizing the drive wheel alone. Accordingly, a travelling movement of the transfer aid mechanism is facilitated if there is a carpet laid over the floor or there is a step in the floor.

Abstract: In a spatial light modulator of the present invention, a photoconductive layer formed of photoconductive material receives write light having a spatial distribution in its intensity and changes resistivity of the photoconductive material dependently on the spatial distribution in the intensity of the received write light. A liquid crystal layer formed of liquid crystal molecules of nematic phase receives read light and presents birefringence with respect to the received read light. An electric voltage is applied through the photoconductive layer and the liquid crystal layer to thereby produce an electric field in the liquid crystal layer. The photoconductive layer changes the electric field produced in the liquid crystal layer in accordance with the resistivity of the photoconductive material so as to electrically control the birefringence of the liquid crystal molecules.

Abstract: In an individual identification apparatus, a hologram 11 recorded on a card is irradiated with laser light to read out a fingerprint image of a specific person. A finger of an arbitrary person to be identified with the specific person is irradiated with laser light to obtain a fingerprint image. Thus obtained fingerprint images are jointly written in a first SLM. Then, the joint image is read out and Fourier transformed to obtain a Joint Fourier Transform image, which is then written in a second SLM. The Joint Fourier Transform image is then read out and Fourier transformed to obtain a pair of output correlation peaks. A photodetector detects the intensity of the output correlation peaks and outputs a signal indicative of the intensity. A threshold processor compares the value of the signal with a predetermined threshold value to positively or negatively identify the arbitrary person with the specific person.

Abstract: A multiprocessor system is provided with processor units which are grouped beforehand into some groups, a system status monitoring unit for monitoring a key input operation of a keyboard, a power demand monitoring unit for calculating the difference between the total power demand of the processor units at the present time and the total power demand of the processor units in a low power-demand mode which is measured beforehand, when the key input operation is not carried out in a normal operation mode for a predetermined time, and an operation clock controller for successively reducing or stopping operation clocks supplied to the respective processor units for each group in turn to shift the current mode to the low power-demand mode. With this construction, a power variation which occurs at the time of the switching operation between the normal operation mode and the low power-demand mode or at the time of power supply/power shut-off can be reduced.

A Fourier transform lens receives the light diffracted and scattered at the objective and Fourier transforms the light to generate a Fourier image, the Fourier image having a high intensity spectral component corresponding to the periodic pattern on the objective and a low intensity spectral component corresponding to the abnormal portion. In an optically-addressed spatial light modulator, each of the optically-addressing part and the light modulating part receives the Fourier image at the corresponding portions.
