A detailed comparison of several approaches to the terrestrial planet finder, was presented. The focus was on three concepts namely an apodized square aperture, a Gaussian Spergel/Kasdin aperture, and a classical Lyot coronagraph with graded field mask. The techniques used were physical optics modeling including Fraunhofer and Fresnel propagations, signal-to-noise analysis, and ray tracing. The results of the comparison show that with a fixed maximum aperture dimension of 4m, the soft edged Lyot coronagraph offers higher performance than other two concepts.
