Simple image acquisition system optoelectronic analysis

The goal of this paper is to make a study about a simple optical images acquisition system as that one used in video mobile phones. 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 two lenses and an aperture. We compute the PSF and MTF for lenses: one with coma aberration and the other without aberrations, then for the aperture and finally PSF and MTF for CCD image sensor. 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
