In fact, for very rapid detection, detector shot noise does not determine the signal-to-noise ratio. Instead, the amplifier has the most impact, which is why many designers have selected a photomultiplier tube for the high-speed or low-light-level detection of photons.The applications where rapid detection of light is a must are many. They include a wide variety: semiconductor inspection, gene sequencing, oil well logging and high-energy physics. The reasons for...Photonics HandbookDetectors: Options for Low-Light Applications: Silicon photomultipliers and photomultiplier tubes each boast unmatched sensitivity, yet their distinct characteristics make them suited for different uses.Developed in the early 1990s, the silicon photomultiplier (SiPM) is a solid-state photodetector whose sensitivity to light rivals that of a photomultiplier tube (PMT) in a regime where a few hundred...Photonics HandbookCamera Resolution: Combining Detector and Optics Performance: Most image-quality discussions center on resolution, which is thought to uniquely determine system performance. Resolution, however, is a more complex concept.Camera resolution depends upon the optical blur diameter and the detector size. Schade combined these to create an equivalent resolution that is a function of Fλ/d where F is the focal ratio,...Photonics HandbookDetectors: CCDs for Life-Science Applications: The CCD camera is becoming the imaging method of choice in biological laboratories for its resolution, versatility and ease of use. Choosing the best CCD for a given application, however, requires knowing how basic chip parameters affect performance.Since their invention in the late 1960s, charge-coupled devices, also called CCDs, have found widespread use in imaging applications.
