Measuring the linear gain performance for the OrcaQuest CMOS imaging sensor
arXiv:2610.00570 · doi:10.1117/12.3105075
Abstract
The OrcaQuest CMOS sensor by Hamamatsu Photonics has been found to exhibit a non-linear gain curve at low exposure times. This effect is characterized through the various exposure tests and data reduction pipelines detailed in this report, and a more accurate gain characterization curve is provided. Such data can be used to provide more consistent measures of pixel gain, linearity, and high framerate images.
