本文通过设计一种基于复杂可编程逻辑器件(CPLD)的脉冲发生器,实现了脉冲周期不间断可调的驱动控制信号的产生,并通过设计DAC控制的快速响应大功率驱动电路对脉冲发生器产生的信号进行功率放大,驱动高灵敏度的1.06 μ m波长发光二极管,有效地模拟了脉冲激光发射的测距信号和制导光场信息,从而解决了脉冲激光设备中接收系统的接收灵敏度和测距机测距分辨能力及制导接收系统的偏航和俯仰制导效果等多参数的非接触不解体测试问题.该模拟测试装置具有测试精度高、体积小、重量轻和可靠性好等特点,适合于在野外在线测试中使用,具有较高的实用价值和良好的推广应用前景. 相似文献

We prepare a new type of multi-wavelength infrared laser diode with four chips, three wavelengths (865 nm, 905 nm and 1064 nm) and two working modes (pulse and single). The preparation technology of the diode includes two key processes: heat-sink and packaging processing technique to package four different chips on a same heat-sink. The experimental results show that four output peak-wavelengths of the prototype diode all possess favorable stability. 相似文献
