PSI introduces a new compact, multi-modal, high-resolution, adaptive- optics, retinal imager. This powerful imaging platform is designed for fast, cone-photoreceptor density mapping and precise imaging of other retinal structures (e.g., Retinal Nerve Fiber Layer, retinal vessels and capillaries, etc.).
The unique capabilities of the new multimodal instrument enables clinicians to gather high quality images of the skin cancer lesions, determine their lateral and depth margins, and guide therapy.
Noninvasive/Minimally Invasive Diagnostics
OCT, combined with other imaging modalities, provides powerful diagnostic capability for minimally- or non-invasive techniques. See the tools we produce for these applications.

Radiation Sensors

OWL is a contextual system that can be coupled with a suite of other detectors to provide actionable intelligence and enhanced situational awareness. The system integrates visible and thermal cameras with PSI’s powerful onboard machine vision and keypoint tracking algorithms. OWL can also operate as a standalone, advanced camera system.
The PERM gamma detector provides gamma detection and isotope identification. It uses a low-cost 2 in x 4 in x 16 in NaI(Tl) crystal, enclosed in an IP67-rated housing, as the scintillation material. The crystal/photomultiplier tube (PMT) package is a commercial item supplied by St. Gobain. The design associated with the packaging of the COTS scintillator is driven by the need to provide medium-resolution (~8%) gamma spectra (30 – 3000 keV) with accurate and stable energy calibration.
PERM-Mobile is an advanced radiation detection and source identification system that can be easily configured for mobile and static applications. The system provides fast vehicle integration with power provided through the 12V vehicle supply. The PERM-Mobile uses a local WiFi network and a tablet which provides the user interface and processes the detection algorithms.
MURS is an advanced mobile radiation detection, identification and source localization system coupled with day/night contextual imaging and inertial navigation subsystems discreetly installed in a 4x4 vehicle. The standard MURS includes a Chevrolet Tahoe SSV and is complete with a low-profile law enforcement package.

Tactical Products

Deployable Man-Portable Antennas

The REEL, Rapid Emergency Evacuation Litter is a revolutionary, lightweight evacuation litter/stretcher specifically designed to meet the needs of tactical field care. It is the lightest and most compact quad folding litter ever made.

ISR Systems

Compact IR 3D range imaging sensor employing compressive sensing (CS) for deployment on small ground and air robotic platforms.
Compact VNIR/SWIR HSI sensor compatible with small rotary wing UAS operation with application to disturbed earth detection and vegetation/mineral mapping
InstantEye®; is a high-performance, low-cost aerial system that can be hand-launched, flown and hand-recovered by a single person in any weather. With a range over 1 kilometer, configurable payloads, and combat system design, InstantEye® is the tactical small unmanned aerial system available today.
Tagging, Tracking, and Locating Tools
PSI has developed a range of low-cost passive and semi-active tagging tracking and locating tools for use in tracking uncooperative targets, marking and navigation, and IFF applications. These capabilities are enabled by unique applications of quantum dots, luminescent chemistry, and hyperspectral imaging of thin films.

Laser Based Sensors

Our pharmaceutical products target aseptic fill/finish manufacturing applications including manufacturing operations that utilize barrier isolators and lyophilization, often used to process the fastest growing segment of the pharmaceutical industry, biopharmaceuticals.
Tunable Diode Laser (TDL) Gas Sensors
Tunable Diode Laser Gas Sensors are typically in situ sensors that take advantage of robust and mature telecom components in order to offer high precision, high accuracy, and highly selective detection of trace gases with application to a variety of commercial, industrial, defense and environmental problems. PSI has also pioneered the application of TDL sensing to measurements of temperature, pressure, velocity, and mass flux.
LIDAR System
Lidar systems are active remote sensing systems. Typical systems collect pulsed laser energy scattered from aerosols or gas molecules to monitor atmospheric properties such as optical extinction, gas and aerosol concentrations, temperature, and winds.
Wide area, high areal coverage rate surface contaminant detection via LWIR reflectance spectroscopy employing eye safe broadband quantum cascade lasers (QCLs) and a high-speed spatial heterodyne spectrometer (SHS) in a handheld sensor package (~ 10,000 cm3, 10 lb).
In-Line Fuel Monitor
The In-Line Fuel Monitor provides real-time measurement of water and particulate contamination levels in fuel distribution systems aboard Navy ships. Qualified for both jet fuel (JP-5) and marine diesel (F-76), the internal laser-based sensing system responds in seconds to changes in the fuel contamination levels, and provides fuel quality reports over the ship’s network to operator control workstations.
Flexible, high-resolution benchtop confocal reflectance Adaptive Optics Scanning Light ophthalmoscope (rAOSLO) and/or fluorescence AOSLO (fAOSLO) small animal imager with simultaneous AO-OCT for routine laboratory imaging applications in animal research.
PSI QCL-based CO sensor
QCL sensors use mid-infrared semiconductor laser sources, either intraband Quantum Cascade Lasers or Interband Cascade Lasers to enable high precision, high accuracy, and selective detection of trace gases such as greenhouse gases and chemical agents with application to a variety of commercial, industrial, defense and environmental problems.
GasScan™ is PSI’s single board platform utilized in multiple TDL sensor products. It is a complete Wavelength Modulation Spectroscopy system on a single 6” x 6” battery-powered circuit board. It includes laser control, data processing and communications yet draws less than 1 W.

RF and Optical Components

We developed wafer-scale processing for the production of a nonlinear optical material called orientation-patterned gallium arsenide (OP-GaAs) and offer for commercial sale QPM frequency converter devices based on this new, high efficiency material.
We produce periodically-poled lithium niobate (PPLN) jin two forms: as a bulk crystal with a thickness of up to 1 mm, and as a waveguide device. Bulk PPLN crystals are tailored for the production of tunable mid-infrared radiation through pumping by commonly-available lasers with wavelengths near 1m. Bulk PPLN devices can produce several W of average power between 2 and 4 micron.
