叙述使分立固体探测器和优选结型场效应晶体管(JFET)放大器能在4K下运用的方法。三种探测器的光谱范围是0.6～4微米,其中有两种探测器的噪声等效功率(NEP)为～10~(-16)赫~(-1/2),而第三种探测器的这一性能有可能得到改进。在较长的红外波长下预料有较低的NEP。
Describes a method that enables discrete solid state detectors and preferred JFET amplifiers to operate at 4K. The spectral range of the three detectors is 0.6 to 4 microns, with two detectors having a NEP of ~ 10 ~ (-16) Hz ~ (-1/2), while the third detector This performance is likely to be improved. Lower NEPs are expected at longer infrared wavelengths.
