Request InfoMartin, Froeschner & AssociatesThe DVI 99 noncontact velocity recording system from Martin, Froeschner & Associates detects spontaneous changes in the frequency of light reflected from a moving surface. This turnkey system, which is housed in a 3-in. rack-mounted chassis, is connected to viewing optics via optical fibers and to a PC-based data acquisition and analysis system. The fast amplified photodiodes located in the data acquisition system can record changes in velocity with subnanosecond resolution. Unlike vibrometers, there are no limitations on maximum velocity or response time. Changes in surface reflectivity or...See full productRelated content from Photonics MediaPRODUCTSPromoted Content October 2023 IssueNear-Eye Display Test SolutionThe diversity of XR devices and their measurement requirements continue to grow — new display types, fields of view, resolutions, focal distances, form factors, and unique combinations of these...Vision Spectra Autumn 2023 Issue3D Laser ScannerThe Absolute Scanner AS1-XL modular 3D laser scanner from Hexagon AB is designed for large surface inspection.
