摘要： A light source device 1 includes a laser light source 10 and an optical phase modulator 15 or the like. The optical phase modulator 15 inputs coherent light output from the laser light source 10 and transmitted through a beam splitter 14, phase-modulates the light according to the position on a beam cross section of the light, and outputs the phase-modulated light to the beam splitter 14. When (p+1) areas sectioned by p circumferences centered on a predetermined position are set on a beam cross section of light input to the optical phase modulator 15, the more outside each of the (p+1) areas is, the wider the radial width of the area, the amount of phase modulation is constant in each of the (p+1) areas, and the amounts of phase modulation differ by π between two adjacent areas out of the (p+1) areas.

摘要： There is provided a solid-state imaging device in which images can be read at high speed. Since an n-th processing circuit (e.g. PU1) can be connected to n-th pixel columns (N1) in respective imaging blocks B1, B2, and B3 via switches Q (1), Q (4), and Q (7), signals from the adjacent pixel columns (N2) are to be processed separately by another processing circuit (PU2) even when a partial readout area R may be small. In addition, an image data arithmetic section 10 specifies the partial readout area R restrictively, which allows for higher speed imaging.

摘要： 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. The liquid crystal layer modulates the received read light in accordance with the birefringence which is electrically controlled in accordance with the spatial distribution in the intensity of the write light received by the photoconductive layer.
