Abstract

Using CCD and CID image sensors, the array of detector elements performs a spatial sampling, which sets a maximum limit (Nyquist frequency) on the spatial resolution. In some sensors the MTF is high at and beyond the Nyquist frequency. By moving the sensor relative to the scene it is possible to obtain samples in between the stationary sampling positions. Thereby, the maximum spatial frequency limit is increased. This paper describes measurements with a CCD image sensor using this dynamic sampling effect. Resolution up to 3.5 times the Nyquist limit is shown. A theoretical calculation of expected obtainable MTF's for different sets of parameters is presented. This can be used to select parameters for best possible result when using the dynamic sampling effect.
