WebLSF is a function of the angle of view which describes the sharpness of the camera. MTF comes as a result of the Fourier Transform of the LSF. Wide spectral range. Precise positioning of unit under test thanks to 2 precise motorised axes. Projector is compatible with all standard cameras and laser range finders. WebJul 1, 2012 · The ideal line source is scanned across the pixel’s sensitive area to find the pixel’s line spread function (LSF). The Fourier transform of the LSF results in the optical transfer function (OTF), the modulus of which is the MTF. The procedure must be repeated for different line source positions, to get a representative performance of the whole FPA. bird recording

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 …
