A bolometer detector system was developed for the high accuracy infrared spectrophotometer at the National Institute of Standards and Technology to provide maximum sensitivity, spatial uniformity, and linearity of response covering the entire infrared spectral range. The spatial response variation was measured to be within 0.1 %. The linearity of the detector output was measured over three decades of input power. After applying a simple correction procedure, the detector output was found to deviate less than 0.2 % from linear behavior over this range. The noise equivalent power (NEP) of the bolometer system was 6 × 10 [Formula: see text] at the frequency of 80 Hz. The detector output 3 dB roll-off frequency was 200 Hz. The detector output was stable to within ± 0.05 % over a 15 min period. These results demonstrate that the bolometer detector system will serve as an excellent detector for the high accuracy infrared spectrophotometer.
美国国家标准与技术研究院为高精度红外分光光度计开发了一种测辐射热计探测器系统，以在整个红外光谱范围内提供最大灵敏度、空间均匀性和响应线性度。测得空间响应变化在0.1%以内。在输入功率的三个数量级范围内测量了探测器输出的线性度。应用简单的校正程序后，发现在该范围内探测器输出与线性行为的偏差小于0.2%。测辐射热计系统在80 Hz频率下的噪声等效功率（NEP）为6×10[公式：见正文]。探测器输出的3 dB滚降频率为200 Hz。探测器输出在15分钟内稳定在±0.05%以内。这些结果表明，测辐射热计探测器系统将成为高精度红外分光光度计的出色探测器。
