摘要：
An anisotropic Bragg device, fabricated out of paratellurite, has been used as the acousto-optic horizontal deflector in a television-rate laser scanner that previously employed an isotropic lead molybdate acousto-optic device as the horizontal deflector. With approximately 50 mw average drive power, at television horizontal scan rate, the deflector produces an average deflection efficiency of 50%. The limiting TV resolution of the scanner is greater than 10 MHz (52 mu sec active line time).
