绝对光谱响应 meaning in Chinese

absolute spectral response

Research of test technology for absolute spectral responsivity of hgcdte detector
Hgcdte探测器绝对光谱响应度测试技术的研究
The approach is that we first calibrate the filter radiometer with cryogenic radiometer and measurement equipment of relative spectral responsivity and then calculate the absolute spectral responsivity . because the drift in blackbody temperature directly influnces measurement accuracy , so we adopt a feedback system to stabilize blackbody temperature through controlling the current of blackbody that improves measurement accuracy greatly
该方法首先要用低温辐射计及相对光谱响应度测量装置对滤光辐射计进行标定，经计算可得到滤光辐射计的绝对光谱响应度；由于黑体温度的漂移直接影响到测量精度，我们采用反馈系统通过控制黑体的加热电流，来稳定黑体温度。
