Work has continued on a large-angle deflection technique for producing a 945 line TV type raster scan in an experimental laser display. A 14 degree scan angle was achieved at 28,350 cycles by the horizontal deflector comprised of a piezoelectric cartridge and mirror coupled by a glass resonator shaft. Cartridges made of PZT-4 material as well as silica fibers are being investigated in an attempt to improve the scanners. Tests to determine angular and lateral deflection, effects of cooling, and mechanical resonant frequencies were performed, and an electrical equivalent circuit was arrived at. Electronic drive circuitry for both horizontal and vertical scanners was further developed. It was concluded that at least twenty-five factors and variables contribute to the characteristics of the scanners. Other type scanners were also investigated. Author
