Article Title: Investigation of the Hue–Wavelength Response of a CMOS RGB-Based Image Sensor

doi: 10.3390/s22239497

Figure Lengend Snippet: H-W curve obtained with Canon EOS D450 using the CFA technology for the wavelengths from 400 to 650 nm. The response of the CMOS camera is not sensitive outside this wavelength region. A monotonic decrease can be seen, and a non-linear H-W relationship is evident. The gray band represents an unavoidable uncertainty due to the beam size and doubled exposure time. In addition, the effect of reflection or dispersion on the screen also needed to be considered. The uncertainty in H was determined by standard deviation on the H distribution for a 2 nm scale wavelength.

Article Snippet: In our study, a camera employing CMOS sensors technology (Canon EOS D series) was used, and this was adequate for our purpose of using bi-alkali PMT-based experiment.

Techniques: Dispersion, Standard Deviation
