Optical information transmitting device and method of manufacturing same

摘要: An optical information transmitting device for on a light beam emitted by source, includes an electronic circuit board, and input/output port mounted the board. The has glass substrate attached to first array of sensors absorbing portion applied thereto from source photoelectrically converting beam, remainder therethrough, second spatial modulators modulating transmittance with respect thereto, arrays being disposed surface in superposed relationship each other. A motherboard comprises coaxial lens lenses spaced at equal intervals along axis substrate, conjugate focusing planes magnification between adjacent ones lenses. method manufacturing is also disclosed.
