科研级相机的灵敏度由三个主要参数决定: 探测器的QE, 像元尺寸和相机噪声。 后两项我们以后再做专题讨论。 这期先讲讲我认为顶顶重要，看起来最容易理解，但是其实还有些奥妙的QE. QE-量子效率QE很容易理解，就是探…

Quantum efficiency (QE) is the fraction of photon flux that contributes to the photocurrent in a photodetector or a pixel. Quantum efficiency is one of the most important parameters used to evaluate the quality of a detector and is often called the spectral response to …

A QE curve is a graph of the Quantum Efficiency vs. wavelength. The following is an interactive plot of the QE curves for cameras based on sCMOS and CMOS imagers.

Quantum efficiency (QE) is the measure of the effectiveness of an imaging device to convert incident photons into electrons. For example, if a sensor had a QE of 100% and was exposed to 100 photons, it would produce 100 electrons of signal. In practice, sensors are never 100% efficient, and different sensor technologies have different QE values.

The Quantum Efficiency (QE) of an imager is an important parameter because it has a significant impact on the sensitivity of a camera at a particular wavelength of interest. However, one should not use it as the sole determinant in camera selection: it should be …

量子效率 – QE（Quantum Efficiency）：在一个Camera Sensor里面，经过Color Filter投射过来的光子转变成为电荷的效率。 自然界中有不同波段、不同频率的光线，我们简单地分成RGB三种不同频率的光线，这三种光线由于频率的不同，每个光子所载有的能量是不同的。

2021年6月16日 · 本文探讨了工业相机的灵敏度，对比了CMOS与CCD的区别，重点介绍了量子转换效率（QE）的概念，强调了光波长对探测效率的影响。

2023年7月11日 · Camera Quantum Efficiency (QE) and Responsivity are similar measurements for the photodetector response to photons. The QE is defined as the ratio of electron numbers to the number of incident photons:

An explanation of the similarities and differences between QE and Spectral Responsivity leads in to a graph that shows the QE curves for sCMOS and CMOS imagers that are used widely in scientific imaging applications.

The Spectral Response (or QE) of the CCD is governed by the ability of the photons to be absorbed in the Depletion Region of the detector. It is only in the depletion region that photons are converted into electronic charges and subsequently can …
