WebMar 31, 2024 · The Point Spread Function (PSF) of an optical system is the image that results at the image surface from a single point source radiated from object space. Aberrations and diffraction cause spreading, resulting in an image that is not a perfect point, despite arising from a point source. WebMeasurements in fluorescence microscopy are affected by blur. Blur acts as a convolution with the microscope’s Point Spread Function (PSF) The size of the PSF depends on the microscope type, light wavelength & objective lens Numerical Aperture (NA), and is on the order of hundreds of nm. In the focal plane, the PSF is an Airy pattern.
WebAug 11, 2024 · By definition PSF is the response of imaging system to a single light beam. At the beginning of the Algorithm 1, considering that no motion tests have been performed yet, the PSF is considered equivalent to a PSF of motionless system so the initial PSF is a matrix whose values are zero and only the central element is one.
