Press Release

Physical Sciences Inc. (PSI) has been awarded a research program from the U.S. Navy, Naval Air Warfare Center, to develop a beach zone mine detection capability based on a novel, high-speed visible-near infrared, shortwave infrared hyperspectral imaging (VNIR/SWIR HSI) sensor.

The VNIR/SWIR HSI sensor employs a digital micromirror device as agile, programmable entrance slits into VNIR and SWIR grating spectrometer channels, each with two-dimensional focal plane arrays. This architecture enables rapid hyperspectral data generation with high spatial resolution supporting fast speed of advance and high specificity airborne mine detection. The HSI will enable detection and discrimination from beach zone clutter of key spectral phenomenology including disturbed sand, grain size, vegetation stress, and surface mines. The sensor will be coupled with an advanced detection algorithm that performs in situ clutter characterization, anomaly detection and spectral, shape, and feature matching against key targets.

PSI’s capability will be able to detect and discriminate anomalies and mine targets including disturbed sand in cluttered beach zone environments from an airborne platform at a rapid speed of advance. Other applications include standoff chemical and explosives detection, vegetation trait mapping, and precision agriculture.

Press Release

Physical Sciences Inc (PSI) has been awarded a research program from the National Institutes of Health (NIH) to develop an ultrasensitive laser-based sensor to accurately monitor ppbv to ~1000 ppmv concentrations of vapor phase hydrogen peroxide (VHP) following decontamination of parenteral drug manufacturing facilities where biologic and cellular therapeutics must be packaged under aseptic conditions.

The need to accurately monitor VHP after sterilization is critical to minimize its deleterious effects on biological drug products and potentially cause shortages of high-demand biologic pharmaceuticals. In addition, batch losses due to VHP contamination results in higher drug costs and reduced revenue. Optical sensors based on tunable laser absorption spectroscopy (TLAS) exist that can monitor VHP concentrations with limits of detection in the ppbv range. However, this approach is prone to interference from water vapor that is present at concentrations several orders of magnitude larger than the VHP concentrations during the aeration phase of decontamination. This impairs the accuracy of existing optical-based commercial instrumentation, and makes it challenging to accurately quantify VHP at ppbv levels.

PSI is demonstrating an innovative optical sensing approach to quantify VHP that suppresses interference from water and enable accurate quantification of ppbv levels of VHP even in the presence of >10,000 ppmv water. This approach will also have a broader dynamic range than existing commercial sensors can achieve, enabling monitoring of the VHP throughout the entire sterilization cycle. It will enable pharmaceutical manufacturers to minimize the loss or reduction in efficacy of biologic and cellular therapy pharmaceuticals due to oxidation from residual VHP.

  • Rocket Propulsion Systems: igniters, propellant health monitoring systems, plumbing components, and engine nozzles.

RSI’s Space Weather Program

Research Support Instruments (RSI), a wholly owned subsidiary of PSI, has begun work on a space weather program that augments their recent work on the currently orbiting Wide-field Imager for Solar PRobe Plus (WISPR); the program has since been renamed Parker Solar Probe (PSP). Whereas PSP focuses on in situ coronal measurements, the Polarimeter to Unify the Corona and Heliosphere (PUNCH) mission will focus directly on the Sun’s outer atmosphere, the corona, and how it interacts with the inner heliosphere.


Illustration of how the four imagers work in concert to obtain a single composite image of the corona and inner heliosphere

PUNCH will make 3-dimensional (stereoscopic) observations of the young solar wind from the solar corona to the inner heliosphere, closing a 50-year gap in measurement and understanding. A constellation of 4 small satellites in Sun-synchronous LEO produces deep field, continuous, 3D images of the corona and young solar wind from 6 to 180 R (solar radii) in polarized visible light. Each spacecraft carries one instrument. A Narrow Field Imager (NFI) captures the entire outer corona from 6 to 32 R. Three Wide Field Imagers (WFIs) capture from 20 to 180 R.

A common imager detector allows images from all four Observatories to be combined into higher order science data products. The images allow detection of a mass ejected by the Solar Corona and tracking of the evolution of the structure of the mass as it enters the Heliosphere and evolves over time.


Depiction the scientific goals of the mission and where they are measured

The program is a joint effort between Southwest Research Institute (SwRI), the Naval Research Laboratory (NRL), and RAL Space. The NRL team will be building the Near-field imager (NFI) and the polarizing filter wheels (PFW) that will be used on each instrument.

Press Release

Physical Sciences Inc has been awarded a research program from the US Navy, Naval Air Warfare Center to develop a Hypersonic Materials Mechanical Strength (HMMS) testbed technology capable of measuring mechanical properties of hypersonic material systems as they are subjected to the thermal shock, high heating rate, high temperature, and oxidative environment experienced at the leading edge of a hypersonic vehicle.

The HMMS testbed resulting from this successful effort will provide the Navy, and subsequently other DoD laboratories and Prime Contractors with a test capability providing quick, inexpensive test data to qualify existing material designs (e.g. batch testing) or to establish the viability of new material designs under development for hypersonic systems applications. The HMMS testbed will help accelerate the development cycle and reduce development costs of hypersonic materials systems compared to other programs that rely on expensive field tests for initial screening and qualification of flight system materials. The technology support’s the current US initiative to accelerate the development of hypersonic systems.

Press Release

Physical Sciences Inc, in collaboration with the Department of Pathology at the Massachusetts General Hospital (MGH) and the Divisions of Pulmonary and Critical Care Medicine at MGH and Beth Israel Lahey Health, is developing and evaluating a novel technology for assessing pulmonary fibrosis, a respiratory disease leading to serious breathing problems, under a research program from the National Institutes of Health.

This disease consists of the accumulation of excess fibrous connective tissue within the lungs (this process is called fibrosis), leading to thickening of the walls of the bronchioles, and thus causing reduced oxygen supply in the blood. Since misdiagnosis is common, a biopsy is ultimately performed to confirm findings. Unfortunately, large pieces of tissue are needed to evaluate the presence of fibrosis so video assisted thoracoscopic wedge biopsy (VATS) is used for this purpose. However, this procedure has multiple side effects and requires tissue processing and pathologic interpretation that makes the procedure expensive, while the results are not immediately available.

PSI’s alternative approach to regular VATS wedge resections is to investigate tissue morphology and mechanical properties in situ by using a minimally invasive needle-type smart optical probe that eliminates the need to remove any tissue. Furthermore, the results are immediately available during biopsy. This technology will open a new avenue for more efficient diagnosis and treatment of pulmonary diseases, while eliminating side effects associated to the regular biopsy, leading to patient improved quality of life and decreasing healthcare costs.
