Detection of Weak Optical Signals in Special-Purpose Optoelectronic Systems, to detect optical signals. This theory is actually applicable to any kind of optoelectronic system: range finders (which not only detect the optical pulse, but also measure the time of its arrival), lightwave communication systems (which register pulse sequences rather than stand-alone pulses), IR

Photodetecting Assembly as Detection System for Weak Optical Signals,ource. Such systems include star orientation devices, IR direction finders, various kinds of passive tracking and aiming systems. Even if the radiation of the source is constant, and there is no modulation or scanning in the system, the measurement time . is still limited, and the optical signal may

Conclusion,m and the power supply maintain the desired temperature and operating regime. Under these conditions the photodetector performs its mission: it detects the optical signal almost without loss, often without introducing any additional noise. Because of this, the thermal background noise prevails in hi

Perspectives and Debates Since the 1970s is cumbersome, and so far we preferred to rely on the frequency analysis. The time-domain analysis can be much simplified, however, by using the approximate technique, based on considering the sequence of samples of signal and noise, and representing the noise as the sequence of pulses of random am
