Abstract: Abstract:To improve the reliability, accuracy and stray light suppression ability,laser diode is commonly used for illumination of space vision measurement subsystem which is used in rendezvous and docking and onorbit operation mission. A design of laser diode driving circuit is proposed, the delayed start ability, constantcurrent driving and overcurrent protection are realized. Experimental results validate the high stability reliability and high accuracy of proposed designing.

Key words: Keywords:space vision measurement, illuminating light source, laser diode, constantcurrent driving
