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 …

The 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… WebThe LSF racquet department offers group and private lessons, both for adults and juniors, as well the more fitness-intensive cardio tennis program, social and competitive flex leagues, … can one apply for social security onlineWebLSF at Illinois Center is the health club that has everything you need to reach your goals.
