Paper Abstract

Our goal in this paper is to make a study about a simple optical images acquisition system. We focus our analyses to optoelectronic aspects using Fourier optics to compute PSF (point spread function) and MTF (modulation transfer function). We use an optical sensor and a CCD (charge coupled device) image sensor to make an image acquisition sensor. Optical sensor is made by a lens and image sensor has an appropriate pixel aperture dimension to reduce Nyquist frequency needed to eliminate alias in CCD image sensor. We compute the PSF and MTF for lens which has two aberration power and coma and for CCD image sensor optical part. We present an image at each checking point and we see how the original image is transformed as it propagates to optical and image sensors.
