Abstract
The knowledge of the precise step-response function of CCD sensors used as transducers is very important for displacement measurements. By the use of this function a subpixel accuracy can be achieved. However, the step-response function of a CCD sensor depends on the environmental parameters, the conditions of illumination, and therefore it is to be determined during rather than prior to the displacement measurements. This paper shows how precisely the step-response function has to be measured to achieve the highest accuracy. In addition, the authors investigate different interpolation methods to determine which step-response function fits best to the measured values.
