The goal of this paper is to generate a laser pulse and to capture it by an image acquisition system. We use a confocal resonator to generate a laser pulse; then the generate light is focused in to an optical fiber using a lens; the light propagates through the fiber and at the fiber output light is projected on a CMOS sensor. We compute the PSF (point spread function) and MTF (modulation transfer function) in order to characterize the functionality of the lens and the optical part of a CMOS sensor. We analyze the CMOS electrical part considering the photon shot noise and the FPN (fixed pattern noise). Finally, we use a Lapacian filter, an amplitude filter and a bilateral filter in order to reconstruct the noisy blurred image. We consider the image capture system to be linear shift invariant, axial and the light is orthogonal to the system.
