Laser Based Sensors

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.
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.).
Low-Cost Magnetometer
Magnetometers find applications in a wide range of Geophysical exploration and environmental sensing systems. PSI’s extensive background in optical sensor phenomenology, including optically pumped alkali atom magnetometers, creates opportunities to develop specialty magnetometers for demanding applications.
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.
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.
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.
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.
TDLAS based water vapor mass flow rate monitor
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.
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.
