WebThe relay lens images the first intermediate image to the second intermediate image. This second intermediate image must be located at the front focal point of the eyepiece. The … WebUse of optical relay lenses allows for convenient interchange of the video camera, CCD, and/or intensifier tube, and provides electrical isolation of the sensitive video camera input from the high voltages and high-frequency electrical interference present on the output of the image intensifier. Bonding fiber-optic tapers to the CCD surface is ...

WebJun 10, 2024 · The non-imaging illumination system designed in this work was mainly divided into two parts, which are microlens array system and double lens concentrator system. In between these two systems, relay lens are usually adopted to adjust the optical path and avoid the structural interference. Microlens Array system Principle and design WebThe invention discloses an optical-waveguide display module with multiple light sources, including a light-source array of timing-orthogonal-characteristic, a relay device, a display device of orthogonal-characteristic, an optical waveguide device, a converging device, a control device, and other components.
