Paper Abstract

This paper describes recent advances in the area of acoustic-traveling-wave-lens technology as applied to optical beam deflection. Test data from a breadboard, beam deflector system will be presented. This system rapidly scans a focused laser beam across a recording medium (for recorder applications) or across an existing image (for readout applications). The scanner uses a Bragg-effect, acousto-optic beam deflector (AOBD) working in series with an acoustic-traveling-wave-lens (ATWL) device to produce an extremely fast, high resolution laser scanner that uses no moving parts. The breadboard system has achieved a resolution of approximately 5000 single-Rayleigh spots per scan line and a bandwidth of 100 MHz. A further advantage of this approach is its excellent linearity. A linearity of one part in 104 has been achieved and a goal of 2 parts in 105 has been established for experiments currently underway. This technology appears to possess excellent growth potential with resolutions of 20,000 spots and bandwidths of 200 MHz being clearly in the realm of possibility.
