Abstract

A vision sensor system composed of a CO2 laser. EOM modulator, holographic scanner, infrared detector, and image processor has been developed. The holographic grating disk scanner is composed of ten facets, and each hologram is made of Ge. The maximum diffraction efficiency of 62.9% is achieved. By rotating the holographic grating disk with the number of revolutions (3000 rpm), it is possible to get images in which the resolution is 10 cm within the distance region of 3-30 m.
