SRI develops sensor technologies with distinct advantages such as high speed, low cost, high sensitivity, and real-time feedback. For clients across many industries, SRI develops, tests, integrates, and deploys customized sensor solutions in these areas and more:

  • Remote sensing of Earth's atmosphere e.g., Advanced Modular Incoherent Scatter Radar
  • Optical sensing in marine environments
  • Trace gas and aerosol sensing to detect hazardous compounds
  • Optical and biological sensors for national defense and intelligence
  • Upconverting phosphor reporter technology for biowarfare defense
  • Light detection and ranging (LIDAR) for standoff detection of harmful biological agents and explosive substances
  • Ultrasensitive laser spectroscopic sensor systems to detect trace species in the atmosphere 
  • Laser spectroscopic and biomedical sensors for medical diagnostics
  • Point-of-care devices for disease diagnosis and radiation exposure monitoring
  • Intelligent sensors for robots to navigate their surroundings
  • Sensor phenomenology and modeling
  • Vibration imaging sensors
