Data and Code for Analyzing Performance of QHY CMOS Cameras

Abstract: Expensive cameras meant for research applications are usually characterized by the manufacturers and detailed specifications [1] are available for them. Suppliers of inexpensive cameras usually do not provide such detailed information about their cameras. This data set provides the acquisition speed and noise characteristics acquired from a monochrome 1.2 megapixel CMOS camera, the QHY5L-II M [2]. The source code provided along with this data set [3] can also be used to acquire similar data for other QHY camer… Show more

“…Our OCT system had a sub-50 dB dynamic range due to the 23ke − equivalent full-well-capacity of our camera [27]. The ease in which the J 0 null subtraction can be implemented helps us to use it for repeated subtraction, which yields higher Signal to Noise Ratio (SNR) than a single subtraction, due to the effect of averaging.…”

“…Hence, the camera needs to be chosen with some care, and needs to have gamma, gain and exposure-time controls at the very minimum. We have shown [18] that with simple observations, we can estimate the noise level CMOS cameras. Sensors exhibiting low-noise characteristics along with a high dynamic range are preferable, but useful work can still be done if the camera's SNR is only 40 dB, as with 8-bit cameras which have a dynamic range of only 48 dB.…”
