Vision and Imaging Sensors / Detectors
Photodetectors provide dual sensor capabilities.
Press Release Summary:
VisGaAs(TM) sensors enable visible and near-IR imaging on one photodetector; both images can be simultaneously acquired, displayed, and analyzed for comparison. Products operate in 400-1,700 nm wavelength and include unclooled VisGaAs focal plane arrays. Suited for laser-based applications, sensors may also be used for spectroscopy and daytime/nighttime covert surveillance operations.

Indigo Systems Introduces VisGaAs(TM)
September 23, 2003 - Goleta, CA - Indigo Systems has developed a dynamic, new new method for processing standard indium gallium arsenide (InGaAs) detector material which enhances the short-wavelength spectral response. The new material, VisGaAs, is a broad-spectrum performing substance that enables both visible and near-infrared imaging on a single photodetector. This advanced capability to capture images in both the visible and near-IR makes it easier to perform tasks that previously required two separate detectors or cameras. Visible and near-IR images can be simultaneously acquired, displayed and analyzed for comparison. Test results indicate VisGaAs can operate in a broad range from 400 nm (short wavelength visible) to 1700 nm (near-IR). Indigo's special processing technique extends the short-wavelength spectral response by providing a 400 nm cut-on wavelength. VisGaAs focal plane arrays (FPAs) are uncooled and use the same readily available starting material as Indigo's well established standard InGaAs focal plane arrays (FPAs) that cover the 900 nm to 1700 nm spectral range.
VisGaAs sensors can be used in many laser-based applications which are found at 850 nm. Other applications for VisGaAs include spectroscopy and any other tasks requiring two sensors to cover the spectral region from the visible to 1700 nm. Simultaneous imaging using ambient visible illumination and NIR laser illumination, and daytime/nighttime covert surveillance operations are two more areas which would benefit from the use of Indigo's new VisGaAs FPAs.
