Optical calculating apparatus

An optical calculating apparatus comprising:

• a plurality of unit components stacked in a pile;
• each one of the units having a pair of electrodes, glass plates and a transmittance control layer located between the electrodes and made of a material having a transparency property effective to vary at least one of the transmittance amounts or transmittance direction of incident light in accordance with the strength of an electric field applied between the electrodes;
• said pile is a laminated pile;
• a region of each of the unit components through which incident light transmits having a predetermined area;
• photoelectric converting means for converting a light which has passed through the lamination of the unit components to an electrical signal;
• the electrodes are spaced in the direction perpendicular to the thickness direction with facing each other;
• and
• wherein at least one unit includes a pair of individual electrodes each of which face a common electrode.
