| Abstract: | In the opto electric imaging system, aliasing will occur when sampling a scene containing spatial frequencies exceeding half of the sampling frequency. Microscanning is a potential method to reduce aliasing effect. Mathematical theory for microscanning based aliasing reduction, including non even cases, is analysed. Computer simulation of microscanning realization for both one and two dimensional cases is presented. |
