Characterization of registered holographic lenses in a photopolymer compatible with the environment

Abstract

In this work it is presented a device to obtain holographic lenses (LH) in an environmentally compatible photopolymer sensitized at the wavelength of 488 nm. Using this device, LHs reconstructed with two lasers (473 nm and 633 nm), of the same focal and diameter have been obtained, with symmetrical and asymmetric experimental setups, and positive and negative focal. The image quality of these lenses is evaluated: experimentally; from the calculation of the MTF and aberrations, obtained by capturing the image of the focus (PSF) with a CCD sensor, and theoretically; by means of software. It is also proposed a method to improve the image quality of LH's that have more aberrations.
