高精度半导体激光器温控系统的设计与实现
Design and implementation of high precision temperature control system for semiconductor lasers
摘要
Abstract
To solve the problem that stability of radiation wavelength and luminous intensity of a laser diode were affected easily by temperature , a high precision laser diode temperature control system was designed . Temperature acquisition circuit was designed by means of AD 620 and LTC1864 and temperature control circuit by MAX 1968 and LTC1655.The whole system was controlled accurately by a TMS 320F2812 controller.Adaptive fuzzy proportion-integration-differentiation control strategy was proposed and the software was achieved .At the environmental temperature around 15℃, control precision of temperature was up to ±0.05℃ when the target temperature was set to 25℃ and 20℃ respectively. Experimental results show that the temperature control system has the advantages of fast response and high stability .关键词
