Advanced Camera and Image Sensor Technology
Dr. Joachim Linkemann
Trying to explain how a digital image sensor, whether CMOS, CCD or other sensoreither, is a daunting task, let alone try to understand its operation. At phenomenon for me is a somewhat complicated concept. So we should be grateful that Dr. JoachimLinkemann has bothered to prepare an interesting and original tutorial (so you candownload here in pdf) on the operation of any digital image sensor, comparing it with a glass of beer.Why the parallelism of a glass of beer with a gentleman? According to Dr. Linkemann, abeaker containing 50.000 Beer drops, and the ability of a sensor is approximately50.000 electrons per pixel, and is therefore easily extrapolated to understand its operation. Thus Linkemann explains in 41 pages of tutorial, and a fun andunderstandable concepts such as dynamic range, signal to noise ratio, among other interesting concepts to understand the sensor.
