telescopeimpulssrespons
Telescope impulse response, sometimes written as telescopeimpulssrespons, is a concept in astronomical imaging describing how an optical telescope responds to a brief, localized light input. In practice, the impulse response of an imaging system is represented by its point spread function (PSF), which shows how a point source of light is distributed on the detector.
The PSF is determined by several factors. Diffraction from the telescope aperture imposes a fundamental limit
Measuring and modeling the PSF is essential for data analysis. Astronomers estimate the PSF from observations
In signal-processing terms, the telescope impulse response describes how the true sky image is convolved with
