“…The constant reverse bias in this same charge amplifier configuration maintains a constant electrical current through the device while the photon-induced current varies in response to light. Signal to noise performance of this CMOS device is reported to be as high as 66 dB at 10 mW cm optical power [39].…”

A review of photodetectors for optical detection in biological applications is presented. The intent is to provide an overview of the performance metrics and trade-offs among popular photodetectors in order to facilitate an easier match among the photodetector, biological stimulus, and optical pathway. The characteristics and nonidealities of fluorescent and phosphorescent reporters, and the properties of optical components such as filters, lenses, and light sources, are reviewed. By accounting for sources of noise in these components, it is shown how to determine metrics for the optical system that can then be converted to photodetector metrics. Defined photodetector metrics include the quantum efficiency, responsivity, noise-equivalent power, detectivity, gain, dark current, response time, and noise spectrum. The operating principles and performance trade-offs of photodetectors are reviewed, and emphasis is placed on photodetectors for integrated compact systems. Top commercial candidates for photodetectors for detecting light emitted from reporters are the photomultiplier tube, avalanche photodiode, and charge-coupled device. Focus is placed on new developments in complementary metal-oxide-semiconductor structures that can provide low-cost, low-power, and low-voltage alternatives to traditional approaches to biological imaging. Reviewed device structures are presented in the context of supporting the development of laboratory-based instruments and compact fully-integrated systems.

“…In particular, in our case, the electrical circuit, as well as the optical unit, should provide filtering of the useful signal against the background of optical interference -the unmodulated background photo signal generated by solar radiation. To solve this problem, as before 16 , we used an automatic gain control scheme (AGC) 17 , which can adjust the gain of the photo signal, improving the sensitivity of the PRD and monitor a signal of a certain frequency, which is proportional to the corresponding optical signal 18 . The block diagram of the design of the photo-receiving device is shown in Figure 2.…”

“…The active area of a detector plays an important role when working with strongly divergent beams from laser diodes. For light sources with very high and/or non-constant beam divergence, it is hardly possible to get all the light into the active area [17,21,22].…”
