Figure 1.3.1 RDI and MRDI Responsivity Curve 1.4 Image Sensor Pixel level processing image sensors are based on the principle that photons induced by charge at the pixel site should be converted to, as nearly as possible, a noise-fre e signal at the pixel site. The application of this principle produces the lowest possible noise and also allows sig[...]
