Everything about Point spread function
Response of an optical system to a point source of light
The point spread function (PSF) describes the response of a focused optical imaging system to an idealized point source of light. In casual terms, for a given camera, it is the blurry blob image captured from pointing that camera at a single speck of light. Wikipedia →
