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. Webcomparisons of using the LSF and ESF to calculate MTF as well as the use of super-resolution to overcome aliasing present in systems where the detector under-samples the optical system response [1]. In the current study, the point of interest is in making changes to how the Fourier transform is used to extract a MTF from the LSF. The methods

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 … WebFounded in 2000, OpticsPlanet, Inc. is the leading online destination for technical and high-performance gear.

WebFunction, or LSF. It can be shown that the MTF, which is defined in terms of sine-wave targets, is actually the Fourier Transform of the LSF curve. Once the LSF measured, the MTF can be calculated in just a few milliseconds using a modern desktop computer. Theory and Measurement of MTF .
WebThe LSF of the laser 2 output pattern is obtained from its radial distribution by integrating over distance y. Then the Fourier transform of the LSF is calculated. Taking the inverse Fourier transform of the above yields the LSF for the entire system. russ orthodox osternThe optical transfer function is not only useful for the design of optical system, it is also valuable to characterize manufactured systems. The optical transfer function is defined as the Fourier transform of the impulse response of the optical system, also called the point spread function. The optical transfer function is thus readily obtained by first acquiring the image of a point source, and applying the two-dimensional discret… schedule of ketamineWebOne includes measuring the LSF directly from an idealized line approximation provided by an image of a slit target and given by equation (2) .
