| contents | Imaging properties of phase-shifting apodizers A. Sauceda P.J. García J. Martínez L. Herrera A. Castro L. García Física, Astronomía y Matemáticas Phase image formation shifting apodizer optical transfer function We discuss the imaging properties of Phase Shifting Apodizers (PSAs) in terms of their Optical Transfer Function (OTF). The capability totransfer spatial frequencies from the input to the output of an optical imaging system, in the presence of focus error, is quantified by inspectingthe three-dimensional Modulation Transfer Function (3D-MTF).We have found that, in the search of novel apodizers for increasing the focaldepth in imaging optical systems, it is not sufficient to analyze the axial impulse response of that system. Some apodizers, even when theyincrease the focal depth along the optical axis, provide poor imaging properties with respect to defocus. Yet we identify specific values forsome important parameters of the PSA that allow us to achieve high focal depth without severally sacrificing the optical performance of thesystem. We present computer simulations of the 3D-MTF of the system that incorporates these apodizers as well as the output images thatcan be obtained with it. 2006 artículo científico 0035-001X https://www.redalyc.org/articulo.oa?id=57065206 en http://www.redalyc.org/revista.oa?id=570 Revista Mexicana de Física application/pdf Sociedad Mexicana de Física A.C.
