Profile Summary

With 25-years of experience in multi-spectral and hyperspectral optical systems, Mr. Fisher is known in the remote sensing community for his hyperspectral imaging system expertise. Mr. Fisher started his career at IBM, working in the optics lab for 5-years developing Thin Film Optical Inspection Systems. From there he moved on to the U.S. Naval Research Laboratory, gaining experience in detector characterization, field deployments, and lens design of tactical surveillance systems. Projects at NRL included dual-band FPA characterization, numerous airborne deployments with the PHILLS sensor, and completing the initial optical design of the COIS payload for the NEMO spacecraft. His primary expertise, for which he is known worldwide, is that of designing and building Offner and Dyson Spectrometers and telescopes. He has designed custom gratings and spectrographs for over ten organizations, of which >20 units are currently flying in commercial and tactical platforms. His latest projects have been the HICO payload optical fabrication for the International Space Station and the Enhanced Modis Airborne Simulator. He has a B.S. and M.S. in Electrical Engineering from Penn State, with additional coursework in optics from the University of Connecticut and the University of Alabama in Huntsville. John lives in the borough of West Chester, PA with his wife and family, and enjoys road and indoor cycling.
