针对碲镉汞红外焦平面探测器，研究了两种暗电流测试方法。降低暗电流直接关系到探测器的信噪比。对所研制的碲镉汞光伏探测器在工作条件下的暗电流大小进行了测试分析。通过对比多组测试结果发现，工作温度及工艺对暗电流具有不同程度的影响。该研究为以后改进工艺和提高探测器性能及筛选效率提供了理论依据。

Two dark-current test methods for or the mercury cadmium telluride(HgCdTe)infrared focal plane detector are studied. Reducing the dark current is directly related to the signal-to-noise ratio of the detector. The dark current of the developed HgCdTe photovoltaic detector under working conditions is tested and analyzed. By comparing multiple test results, it is found that the operating temperature and process have different degrees of influence on the dark current. This study provides a theoretical basis for improving the process, detector performance and screening efficiency in the future.
