WebApr 14, 2024 · The rapidly growing number of space activities is generating numerous space debris, which greatly threatens the safety of space operations. Therefore, space-based space debris surveillance is crucial for the early avoidance of spacecraft emergencies. With the progress in computer vision technology, space debris detection using optical sensors … A spatial filter is an optical device which uses the principles of Fourier optics to alter the structure of a beam of light or other electromagnetic radiation, typically coherent laser light. Spatial filtering is commonly used to "clean up" the output of lasers, removing aberrations in the beam due to imperfect, dirty, or damaged optics, or due to variations in the laser gain medium itself. This filtering can be applied to transmit a pure transverse mode from a multimode laser while blockin…
WebApr 29, 2015 · A spatial filter is a device to 'clean up' a laser beam with an irregular intensity profile, and create a smooth Gaussian profile at the output.. It is usually said (e.g. here) that you need a microscope objective and a pinhole for this.The microscope objective creates the Fourier transform of the laser beam at its output. The pinhole acts as a low-pass filter in … Web2.3 Optical spatial flltering Fourier transform by a lens: Optical spatial flltering is based on the Fourier transform property of a lens (see Fig. 1). It is possible to display the two-dimensional spatial frequency spectrum of an object in such a way that individual spatial frequencies can be flltered. This property is illustrated below.
WebSpatial filters allow the user to remove random fluctuations from the laser beam’s intensity profile, significantly improving an optical system’s resolution. This laser beam cleanup is especially important for applications such as holography and optical data processing.
