Abe_PSF2: Point Spread Function
Abe_PSF2 is a 32-bit Windows PC program that shows how the wavefront shape and the transmission function of an optical system will affect its image blur, formally called the point spread function (PSF). The image degradation from wavefront effects such as third order aberrations (coma, spherical, astigmatism) and defocus, Zernike polynomial coefficients, discontinuous phase errors (waffle, checkerboard, or random), and/or a subaperture phase plate are simulated. The blur growth from the transmission losses due to obscurations from secondary mirror struts or a central obscuration are modeled, as well as apodization effects or speckle. The pupil can be round, hexagonal, or rectangular, and the system wavelength and f/number are user selectable. All effects may be simulated independently or in combination. Our Review: Well, I've done stage one physics at university, and quite honestly, I don't understand what this program does. Well, I have some idea, but no real in-depth understanding. So, if you know about what the description describes then download this program It's very easy to use, and nicely presented, and I'm sure it does the job.
