中文摘要:针对目前没有设备可对数字化红外探测器的光谱响应进行测试,利用可测模拟电平输出型红外探测器光谱的傅里叶光谱仪,研制了一块电路板装置,实现了将数字化红外探测器转换为与模拟红外探测器一样的输出形式,解决了数字化红外探测器光谱无法测试的问题,且具有结构简单、一板多用等特点,可在不同型号的傅里叶光谱仪上使用。该方式成本低且易实现,不仅操作简单,而且测试性能稳定,适应于各种形式的数字化探测器,使得数字化红外光谱响应测试系统具有更高的兼容性和灵活性。首先对红外光谱响应测试系统进行了介绍,然后对所研制的模数电路板装置进行了原理分析,最后对此电路板进行了硬件实现,并编写了内部测试程序,进而完成了功能验证。理论分析和硬件功能验证表明,带有新研制模数电路板装置后的红外光谱测试系统不仅可以实现不同位宽输出的数字化面阵探测器或线列探测器光谱测试,而且光谱测试结果准确可靠。

Research on Spectral Response Test System of Digitalization Infrared Detector
Abstract:In view of the fact that there is no equipment to test the spectrum of digital infrared detector at present, a circuit board device is developed by using Fourier spectrometer which can measure the spectrum of analog output infrared detector, and the digital infrared detector is converted into the same output form as analog infrared detector. It solves the problem that the spectrum of digital infrared detector can not be measured, and has the characteristics of simple structure, multi-purpose board and so on. It can be used in different types of Fourier spectrometer. The cost of this method is low and easy to implement, which can not only operate easily, but also has stable test performance. It is suitable for various forms of digital detector, which makes the digital infrared spectral response test system have higher compatibility and flexibility. In this paper, the infrared spectral response test system is introduced, and then the principle of the analog-to-digital circuit board device is analyzed. Finally, the hardware implementation of the circuit board is carried out, and the internal test program is compiled to complete the functional verification. Theoretical analysis and hardware function verification show that the infrared spectral test system with newly developed analog-to-digital circuit board device can not only realize the spectral test of digital area array or line detector with different bit width output, but also the spectral test results are accurate and reliable.
