OPTICAL COMPARATOR Russian patent published in 1998 - IPC

FIELD: optical computer engineering. SUBSTANCE: device has second deflector, collimating lens, rectangular prism and three output branches. Control inputs of both deflectors serve as inputs of comparator. Information inputs of first deflector is connected to source of constant collimated light beam. Output of first deflector is connected to upper half-plane of information input of second deflector through lower plane of lens and reflecting plane of prism. Optical center of output of second deflector is connected to input of second output branch. Both output half-planes are connected to inputs of first and third optical branches. Outputs of output branches are device outputs. EFFECT: increased functional capabilities. 1 dwg
