ABOUT US

Sensors Unlimited - UTC Aerospace Systems, is the world’s leading manufacturer of indium gallium arsenide (InGaAs)-based imaging products. As renowned experts in shortwave infrared (SWIR) imaging, Sensors Unlimited, Inc. introduced the world to the concept of imaging in the shortwave IR spectrum with simple, compact, and uncooled cameras.

We offer a wide variety of InGaAs-based products, such as high performance, near-infrared (NIR) and SWIR cameras, and 1- and 2-dimensional focal plane arrays for use in military, aerospace, biomedical, commercial and industrial applications. Our in-house indium gallium arsenide III-V foundry features Class 100 clean rooms and an MOCVD epitaxial growth wafer fab, plus a 20,000 square foot detector manufacturing facility.

ADVANTAGES
The advanced InGaAs detector technology allows imaging in the SWIR without the necessity of an external cooling system. Other benefits of our proprietary sensor technology are low power consumption and the ability to image at high frame rates, a remarkable advantage over current uncooled microbolometer technology. Our NIR cameras deliver what thermal imagers cannot – clear, lifelike detection in daylight or lowlight. Small and compact, they operate at room temperature with no moving parts and can image through glass and plastic using off-the-shelf glass optics. Because our InGaAs cameras have non-uniformity corrections (NUCs) that last for the lifetime of the cameras, they do not need NUCs in the field, making operation simpler.

APPLICATIONS
InGaAs arrays and imagers are ideal for a wide variety of military, industrial, biomedical, telecommunications, scientific and commercial applications. These include:

  • Laser tracking for weapons and communication systems
  • Covert and fixed site surveillance
  • Free space communications
  • Ground and air UV payloads
  • Gimbal sensor assemblies
  • Night vision
  • Near-infrared spectroscopy
  • High speed imaging and tracking
  • Target recognition
  • Driver vision enhancement
  • Food processing and inspection
  • Laser beam profiling
  • Imaging hot processes, e.g. glassmaking and metal smelting
  • Security and surveillance
  • Linescan inspection
  • Microscopy
  • Art conservation
  • Astronomy
  • Solar cell inspection

  • SWIR Camera Utilized In Cutting Edge Tornado Research

    A team of researchers at Purdue University’s Earth, Atmospheric, and Planetary Sciences Department recently tested the practicality of using shortwave infrared (SWIR) imaging for improving the detection of poorly-visible tornadoes in supercell thunderstorms. The team turned their attention to the Churchill Navigation ION digital recorder. The recorder’s ION and CameraLink adapter allowed the team to quickly connect and record video and metadata simultaneously from two different types of cameras; a SWIR camera provided by Sensors Unlimited and a visible-light camera.

  • What is InGaAs?

    InGaAs is an alloy of gallium arsenide and indium arsenide, and is a III-V compound semiconductor. Creating this material is a complicated process, so why go through all the trouble? This article discusses InGaAs in detail and offers benefits for using this technology for SWIR and other imaging applications.

  • SWIR And The U-2

    The U-2 spy plane is the leading reconnaissance platform for the United States with the ability to see at great lengths inside national borders with a closed airspace. The camera used in today’s U-2, SYERS, uses electronic sensors to see in both the mid-wave infrared (MWIR) band (thermal energy) and the short wave infrared (SWIR) band (reflected light). It is the SWIR band that gives the SYERS its remarkable atmospheric penetration capability in reflected light.

  • The Third Infrared Window

    Long wave infrared (LWIR) and mid-wave infrared (MWIR) sensors and cameras have been used in military settings for detecting human activity through thermal emissions. Using the short wave infrared (SWIR) portion of the spectrum extends unique capabilities that often compliment LWIR and MWIR imaging. Until recently, the only way to see in this part of the spectrum was to use large, cryogenically cooled sensors. However, Sensors Unlimited of Princeton has produced small, uncooled cameras using the new indium gallium arsenide (InGaAs) semiconductor material.
