Abstract:
1. Two-coordinate acousto-optical UV laser scanner comprising: a. a collimator having optical axes aligned with the axis of incoming UV laser beam; b. a first and a second identical crystals that are transparent for UV radiation, wherein said second crystal is turned around axis of said laser beam on 90 arc degrees; c. a transducer transforming electrical RF signals into acoustic ones, wherein said transducer is positioned on one side of each said crystal in such a way that acoustic wave is propagate in each said crystal at Bragg angle; d. a resin layer absorbing said acoustic wave, wherein said layer is positioned on one side of each said crystal that is opposite to side where said transducer is positioned; e. a first electronic unit programmable developing said RF signals feeding said transducer of said first crystal, wherein output of said unit is in electrical connection with said transducer of said first crystal; f. a second electronic unit programmable developing said RF signals feeding said transducer of said second crystal, wherein output of said unit is in electrical connection with said transducer of said second crystal; wherein the improvement comprises: said first and said second crystal being made of KDP (KH said transducer comprising two and more 30-micron plates of LiNbO said electronic units having external triggering inputs, which allow synchronizing pulses of said laser with said RF signals feeding said transducers so providing pulse feeding of said transducers.
