Press Releases

Physical Sciences Inc (PSI) has been awarded a research program from the US Navy to develop the Simplified Atom Interferometer Laser System (SAILS) that will be capable of generating two frequency-referenced and phase-coherent optical wavelengths to reduce the size, weight, and complexity of the optical systems that support portable atom interferometry based sensors.

Physical Sciences Inc. (PSI) has been awarded a contract from the U.S. Department of Homeland Security Science and Technology Directorate to participate in Phase II of the DHS Small Business Innovation Research Program. PSI will develop a deep-learning based classification algorithm for detection and classification of trace explosives, opioids and narcotics on surfaces for optical spectroscopic systems.

Physical Sciences Inc (PSI) has been awarded a contract by the US Army to develop the Low-Shot Object Tracking and Targeting (LOTT) system that integrates state-of-the-art machine-learning object detection and tracking capabilities with IR and visible imaging sensors utilizing “low-shot” training techniques.

Physical Sciences Inc. (PSI), in collaboration with University of Michigan, has been awarded a contract from the Naval Air Warfare Center to design, develop, and demonstrate a rotating detonation combustor (RDC) for gas turbine engine augmentors.

Physical Sciences Inc. (PSI), has received a contract award from the Naval Air Warfare Center to develop and demonstrate a low cost, accurate, and single-use aiming device for Explosive Ordnance Disposal (EOD) disrupters.

Physical Sciences Inc. (PSI) has been awarded a contract from National Aeronautics and Space Administration (NASA) to develop integrated optical frequency shifters to enable Quantum-memory Wavelength-Division Multiplexing (QWDM).

PSI-lead Team Selected by the DoD Industrial Base Analysis and Sustainment Office To Demonstrate Pilot Scale Extraction, Separation, and Refinement of Critical Minerals from Domestic Ponded Coal Ash Resources

It is with great sadness we report the passing of Bob Weiss, who died suddenly on May 6. Bob was an inspirational leader who founded Physical Sciences Inc. (PSI) in 1973. He created the approach and basic model that has led to our decades of growth – based on technical excellence, clear communication, and a focus on seeing our advances benefit our nation and the world. From the outset, he realized that people were the essential element that enabled a great and enduring company.

Physical Sciences Inc. (PSI) has been awarded a research program from the National Aeronautics and Space Administration (NASA) to develop a fail-safe field emission-based cold cathode ionizer for use in space-based instrumentation.

NASA has expressed a need for advanced neutral particle ionizers to enable the next-generation of neutral particle detectors such as mass spectrometers for the study of Earth-Sun interactions and planetary atmospheres.

Physical Sciences Inc. (PSI), in collaboration with Boston University, has been awarded a research program from the U.S. Department of Homeland Security to develop a compact and fieldable diagnostic sensor for the rapid multiplexed detection and identification of biological threats.
