The quantum efficiency of a charge-coupled device (CCD) is a property of the photovoltaic response defined as the number of electron-hole pairs created and successfully read out by …

For the STIS CCD, the default gain value of 1 offers the lowest read noise, but the analog-to-digital converter then limits the maximum signal that can be detected without saturation to …

2010年5月4日 · This effect (called “quantum yield”) of a single photon producing more than one electron must be taken into account properly when estimating the noise level for short …

This article explains the principal of quantum efficiency in high energy CCD detectors with respect to X-ray detection.

2019年7月1日 · By understanding the noise sources and quantifying them accurately, we can better estimate the photometric precision and the expected science yield for the mission. Very …

The quantum yield is the number of charge carriers generated per interacting photon (Janesick 2001). For CCD detectors in the optical, each detected photon usually gen-erates a single …

CCD Grading. Manufacturers of CCDs grade devices according to the number and type of defective pixels. The manufacturing yield of each sensor grade strongly affects the CCD cost; …

A simple equation for CCD yield depending on the technological environment condition is derived. An approach demonstrated can be generalized to analyze the yield relating problems for many …

2020年1月1日 · The simplicity of CCD devices (fewer transistors and other structures compared to CMOS sensors) tends to produce higher yield at very large areas. It is certainly true that …

2020年5月25日 · In order to determine the overall signal-to-noise ratio (SNR) of a CCD imaging system, we need to know the magnitude of the signal generated in response to incident light …
