Description

Technical Field

[0001] The utility model relates to the technical field of single-photon detectors, in particular to a fixing device for single-photon detectors. Background Art

[0002] A single-photon detector is an ultra-low noise device whose enhanced sensitivity enables it to detect the smallest energy quantum of light - the photon. A single-photon detector can detect and count individual photons, and can be used in many emerging applications where the available signal strength is only a few photon energy levels. It is expected to be widely used in biophotonics, medical imaging, non-destructive material inspection, homeland security and surveillance, military vision and navigation, quantum imaging, and encryption systems.

[0003] At present, the single-photon detector is mainly fixed by placing it directly in a preset through hole inside the heat sink, and the temperature generated by the single-photon detector is derived through the heat sink. When the box where the single-photon detector is located is moved, there is a situation where the single-photon detector is not in close contact with the heat sink, which can easily cause the single-photon detector to shake, resulting in unstable performance of the single-photon detector and a low bit rate of the communication system. In addition, the single-photon detector is generally installed and fixed with screws, and disassembly and installation are time-consuming and labor-intensive.

[0004] Therefore, a fixing device for a single photon detector is needed to solve the problems raised in the above background technology. Utility Model Content
