Abstract:
This report describes the continuing effort on a large angle of deflection technique for producing a 945 line T.V. raster scan in an experimental laser display. It was determined that 23 KC is the approximate limiting frequency for reliable operation of a resonant piezoelectric type scanner. Both PZT-4 and PZT-5 cartridges were tested. The development of a new type magnetostrictive tortional transducer, having a 14 degree deflection at 28 KC, was reported. This scanner has the potential to exceed the horizontal resolution required for a 945 line raster and is considerably more rugged than the piezoelectric type. The vertical scanner work has been directed toward the evaluation and compensation of a position feedback scanning system. A flyback interval of 2 milliseconds was achieved with 1.25 milliseconds as a goal. Preliminary mechanical design and layout of the deflector module has been completed and test procedures for the scanner system were outlined and evaluated. Author
