摘要A high-precision and small-volume focusing mechanism was designed to realize the distance and temperature focusing functions of the visible light television. Based on the optical design results and functional demands of the visible light television, the main technical indices of the focusing mechanism were proposed. Then, precise linear motor and exact linear guides were chosen, platform base with high stiffness was designed in detail, and formula of focusing distance were calculated, according to the technical indices. The application of high-performance elements and components had ensured the operation performance of the focusing mechanism itself and the resolving of accurate calculation of focusing formula had ensured the focusing effect of the visible light television. Finally, stroke, resolution and precision of focusing mechanism were tested by inductive micrometer and autocollimator upon the completion of precision machining and adjustment of the focusing mechanism. The results show that: the designed focusing platform has small volume (80 mm90 mm30 mm), large stroke (-2.5 mm~+2.5 mm), high resolution (6 m) and high precision of total stroke (azimuth and pitching deviations are no more than 10); and the calculation formula of the focusing amount is correct, which can guarantee the realization of system distance and temperature focusing functions for visible light television. 2017, Science Press.
