Title: Fred L. Schaff: Innovator in Acousto-Optic Technology
Introduction
Fred L. Schaff is a notable inventor based in Ellicott City, MD, with a focus on advanced optical technologies. He holds two patents that showcase his innovative contributions to the field of acousto-optic devices. His work has significant implications for imaging and spectroscopy applications.
Latest Patents
One of Schaff's latest patents is the acousto-optic spectrometer/polarimeter. This device is designed for analyzing an incident broad-band beam using an acousto-optic tunable filter (AOTF). It separates the incident broad-band beam into a diffracted extraordinary narrow-band beam, a diffracted ordinary narrow-band beam, and at least one undiffracted broad-band beam. The system includes detectors that provide signals based on the received beams, allowing for simultaneous broad-band imaging, spectroscopy, and polarimetry through the same optical aperture.
Another significant patent is the ultra wide field-of-regard multispectral imaging radiometer. This imaging radiometer scans an area of interest from a platform moving in an orbital trajectory. It features a moving scanning mirror that produces a changing scan area image. A fixed optical viewer directs the image along its optical path, while a detector receives the changing scan area image over a selected time interval. This invention incorporates image motion compensation and electronically controlled light intensity gain, enhancing the accuracy and efficiency of the imaging process.
