Visidyne Inc, located in the Greater Boston Area with satellite offices in Huntsville, AL and Santa Barbara, CA., was originally formed by members of American Science and Engineering to preform scientific studies and modeling of infrared backgrounds in the upper atmosphere resulting from high-altitude nuclear detonations. At the beginning Visidyne built unique infrared and vacuum ultraviolet sensors for measuring the atmospheric effects of these high altitude nuclear tests. Many of the early employees who joined Visidyne had participated in the atmospheric nuclear tests of the late 1950s and early 1960s. Visidyne has since been working on is known as the Russian American Observational Satellite program, or RAMOS, and supports the International Cooperative Technology Experiments under the Missile Defense Agency (MDA). RAMOS is a cooperative R&D program between the United States and Russia that has both defensive capabilities, like early warning and missile tracking, alongside environmental-related objectives, such as hurricane prediction and monitoring of environmental disasters. The space borne platforms for this work consist of a pair of satellites providing stereo views of selected areas of the earth in order to accurately track rockets. The firm also develops infrared instrumentation used for various government and military applications for laboratory, field and space measurements and provide atmospheric optics R&D services. Other currently-active government-sponsored technology developments include: A 3D imaging camera using lidar-based phase-derived range and an active focal plane array being developed by MIT/Lincoln Laboratory. This technology could form the basis for real time sniper location; An ultrasensitive, pico tesla-level, magnetic sensor that does not require cryogenic components; and Polarization modeling of clouds and aerosols. Atmospheric modeling (cloud transmission and scattering phenomena, cloud thermal and solar scatter radiance, polarization effects); Remote sensing (satellite, balloons, aircraft, and ground platforms); Space physics (satellite sensors and orbital mechanics); Nuclear and atmospheric effects (infrared and visible emissions and ionization concentrations); Electro-optical systems and sensors (ground, airborne, balloon and satellite platforms); Space-based sensors (visible and infrared push brooms, multi-color imagers, and polarization sensors); Precision stabilized balloon borne pointing and tracking systems and payloads; and Optically based measurements (magnetic, mechanical, and optical sensors)
