Abstract:The traditional control system has some problems such as poor sensitivity control, unstable performance and so on. It can not meet the standard of effective control. The optimization design of photoelectric target sensitivity control system is put forward. According to the actual condition and design principle of interference elements, starting from the angle of photoelectric target sensitivity control temperature gun ballistic, converting the optical signal for the weak current signal of weak current signal conversion, design of photoelectric target sensitive controller and photoelectric conversion circuit, complete system hardware design; selection of software development environment based on the optimization of plate the realization of software programming, optimize the photoelectric target sensitivity of control system. The experimental results show that the sensitivity control of the system is strong and the performance is stable.
