WebThe theoretical maximum optical resolution of optics is determined by diffraction effects of light which mainly depend on the wavelength of the light and the slit (aperture). According to the Rayleigh criterion (remaining contrast of approx. 15 per cent), two image points can still be distinguished when the distance of the points dx = 2 * 1.22 * f-stop * wavelength. WebFeb 6, 2024 · Optical fiber sensors are used for partial discharge detection in many applications due their advantage of strong anti-electromagnetic interference capability. Multi-point distributed partial discharge detection and location are important for electrical equipment. In this paper, a distributed partial discharge location and detection scheme …
