Abstract

Automatic high precision laser scanner has been manufactured. It consists of acousto-optic deflector (AOD), optics, drive power generator connected with computer and laser. Two modifications of laser scanner were developed. The first modification has two AODs manufactured from TeO₂ crystal with the following specification: the number of resolvable spots is 500*500, access time is 15 microsecond(s) ec, aperture dimensions equal to 10*10 mm², acoustic center frequency is 75 Mhz for visible and 34 Mhz for IR spectrum, input optical polarization is linear, maximum optical efficiency for one AOD is 90%, drive power is 1 W per one AOD. The second modification has one XY-dimensional AOD manufactured from KRS-5 crystal with the following specifications: spectral range - (0.6 - 1.1) (mu) , input optical polarization - any, active aperture - 6*6 mm², access time - 7 microsecond(s) , acoustic center frequency - 100 Mhz, RF input impedance - 50 ohms.
