    摘要： A light-light transfer method using a spatial light modulator realizes an image display with a high utilizing of light without causing an undesirable residual image. The spatial light modulator is constituted to include two electrodes and at least a photoconductor layer member and a photo-modulation layer member used in a birefringence operating mode both being sandwiched between the two electrodes. A writing light is entered from the photoconductive layer member side so that its exposure value varies from the minimum exposure value to the maximum exposure value in a condition that a predetermined operation voltage is supplied between the two electrodes. In this instant, a voltage applied between both ends of the photo-modulation layer member corresponds to a voltage obtained by subtracting a voltage drop amount, occurring in the photoconductor layer member due to an incidence of the writing light, from said predetermined operation voltage applied in advance between said two electrodes. An operational condition of the spatial light modulator is set so that the voltage applied between both ends of the photo-modulation layer member becomes a voltage monotonously exceeding a voltage value corresponding to an extreme value of a degree of photo-modulation in a characteristic curve showing a relationship between an applied voltage and a degree of photo-modulation in the photo-modulation layer member, at the timing when the writing light of the maximum exposure value is entered into the spatial light modulator.

    摘要： A drive apparatus for an optical element array includes a counter counting clock pulses and being periodically reset at a horizontal scanning period. The counter outputs first and second counter signals out of phase with each other. A latch holds a pixel-corresponding segment of an input image signal. One of clock signals out of phase with each other is selected in response to the pixel-corresponding input-signal segment held by the latch. A first comparator compares the first counter signal and the pixel-corresponding input-signal segment held by the latch, and outputs a first identity signal when the first counter signal and the pixel-corresponding input-signal segment are equal to each other. A second comparator compares the second counter signal and the pixel-corresponding input-signal segment held by the latch, and outputs a second identity signal when the second counter signal and the pixel-corresponding input-signal segment are equal to each other. A drive pulse is generated which starts in synchronism with a start of a horizontal scanning period and which ends in response to the selected clock signal and in response to the first and second identity signals. An optical element in the array is driven in response to the drive pulse.
