滤光片在红外焦平面探测器截止波长测量中的应用

介绍了一种用滤光片估测红外焦平面探测器截止波长的方法。这种方法只需测量出加上滤光片后器件输出响应电压的损失率就可以通过理论计算估算出器件截止波长的大小。通过一个实际的例子说明了该方法的计算过程与结果，并与用单色仪所测得的结果进行了比较，二者符合得比较好。在实际应用中可作为一种筛选器件的快速判断方法。

Application of Filter in Measuring Cutoff Wavelength of IRFPA Detectors

A method of estimating cutoff wavelength of IRFPA detectors is introduced.This method is relatively simple and easy.Cutoff wavelength of detectors can be calculated theoretically by measuring the losing ratio of its output voltage with the filter.An example is presented to explain how to get the cutoff wavelength of detectors using this method,and to compare with the result measured by monochromator.The compared results show that they have a good agreement with the measured data.In practical application it ...
