用于辅助光校的高精度五维调节架设计

Design of the 5-dimension Adjusting Mechanism for Assisting Optical Adjustment

随着光学系统的日益广泛使用,光学系统光校的复杂度逐渐体现出来。高精度、自动化、定量化的多维调节架成为光校系统的技术保证。针对某光学系统镜子重量大、精度要求高,设计了五维调节架机械机构、控制系统。即采用步进电机驱动滚珠丝杠副带动镜子走动、通过编码器进行位置测量,采用计算机和无线小键盘控制五维调节架定量化走动,给出了系统的机械设计、电控硬件和控制软件设计,并对其中的关键技术做了重点阐述。

As the three-mirror off-axis optical system is applied more and more widely, the complexity of the optical adjustment is becoming obvious. The multi-dimension adjusting mechanism with high precision, automatization and quantification has provided technical ensuring for the optical adjusting system. To achieve high precision for controlling and bear heavy mirrors of the thre-emirror system, the mechanical and controlling structure for the 5-dimension mechanism has been designed. Specifically, the stepper motor drives the ball screw to move the mirrors, and the encoder measures the position, and the computer and the wireless mini-keyboard manipulates the quantified movement of the 5-dimension mechanism according to the position signal. The mechanical design and the hardware and the software for electrical controlling are given and some of the key technique are explained significantly.
