光子探测通常是需要最高灵敏度光测量的精选方法。从医疗诊断到高能物理领域 ,光学方法最常用于探测极少量抗体或罕见的现象 ,因为在接近皮秒的时间分辨率下易于探测单个光子。如果光子达到高频或者信号持续时间有限 ,就需要具备高带宽、高放大倍数和高灵敏度的光学探测器。只 Photon detection is often the method of choice that requires the highest sensitivity light measurement. From medical diagnostics to high-energy physics, optical methods are most commonly used to detect very small amounts of antibodies or rare phenomena because of the ease of detecting individual photons at temporal resolutions close to picoseconds. If photons reach high frequencies or signal durations are limited, optical detectors with high bandwidth, high magnification and high sensitivity are needed. only
