WebThe photon transfer curve is one of the most valuable tools for calibrating, characterizing, and optimizing the performance of CCDs and CMOS Imagers. Its primary purpose is to … WebFigure 1 shows the full photon transfer curve and the apparent change in the measured conversion gain with signal level for a VIRGO-2K detector, SCA-module#31. Th e apparent change in the conversion gain as measured by the photon transfer technique is typically up to 15% for signal levels ranging from 20 to 70% full well capacity.
WebIn Figure 1, the shot noise characteristics of light are plotted as a function of illumination level on a LogLog graph. The rms value of shot noise is equal to the square root of the mean number of photons incident on a given pixel. Thus, the shot noise profile becomes a straight line with a slope of ½ on the Log-Log curve (since Log X1/2 = 1 ...
