Quantitative Analysis of Aliasing Effects in Opto-Electric Imaging Systems
In opto-electric imaging systems, aliasing will occur when sampling a scene containing spatial frequencies exceeding half of the sampling frequency. By the use of vector analysis method, a quantitative aliasing expression for an sinusoidal elementary image is given. Moire effect as an aliasing phenomenon of periodic objects and aliasing contents as signal dependent noise of non-periodic objects are analysed. Computer simulations are presented for both cases.
