WebAn IR camera is sometimes sensitive to the temperature difference between an object and its background.Consequently, some tests require to simulate an object and its background and to have a simultaneous and accurate measurement of both. The simulation of an object and its background is made by placing a target in front of the emissive surface of a … WebThe spatial resolution of an x-ray or CT system is a measure of how the ability of a system to differentiate small structures. If you imagine imaging a very small point like object an image of that object is called the Point Spread Function (PSF). When this function is radially averaged the Line Spread Function (LSF) is generated.

"The point spread function (PSF) describes the response of a focused optical imaging system to a point source or point object. A more general term for the PSF is the system's impulse response; the PSF is the impulse response or impulse response function (IRF) of a focused optical imaging system. The PSF in many contexts can be thought of as the extended blob in an image that represents a single point object, that is considered as a spatial impulse. In functional terms, it is … " - Optics lsf
