Abstract

Linear high-speed opto-mechanical scanning at TV and sub-fractional TV line rates is commonly achieved today with multi-faceted rotating polygons. An alternate near-linear scanning means is now available: a linear resonant scanner. The linear resonant scanner is a dual mode torsionally resonant system designed to simultaneously resonate at a fundamental and a third harmonic of the fundamental. An electronic circuit with a precision position sensor is used to control the scan amplitude and phase lock the two natural resonant frequencies. Design criteria and performance parameters are discussed for a 2 kHz linear resonant scanner with a 0.5 radian near linear scan angle, 88% bidirectional scan efficiency, and 18 mm pupil.
