Infrared imaging technology offers a way to measure temperatures of objects that do not easily lend themselves to physical contact. All objects emit electromagnetic radiation, primarily in the infrared waveband for objects at terrestrial temperatures. One of the most useful wavebands for thermography is the midwave infrared, or MWIR band. Small changes in temperature produce large relative changes in flux, leading to increased thermal contrast over other infrared wavebands, that in turns leads to more accurate temperature measurement.

For many years the scientific, range and phenomenology, and research market has seen major advancements in thermal imaging systems to help identify, measure, and track the heat signatures/energy signatures of various sources, both friendly and foe. The fast paced sensor and software advancement has sometimes resulted in misused terms and improper data Representation. More>

This paper describes the advances to the Indigo Systems family of Commercial-off-the-shelf (COTS) hardware and software. Indigo PhoenixTM camera family is being advanced to meet the demanding needs of advanced range & phenomenology applications by including things like IRIG-B time stamping, fiber optic communications, environmental enclosures, and the new RTools radiometric software suite More>

This paper describes a high performance 320 by 256 readout integrated circuit (ROIC) designed for P-on-N short wave infrared (SWIR) detectors including InGaAs and HgCdTe, which also has the ability to operate at low input current levels with N-on-P detectors. More>

Many customers have asked for data on the relative spectral response of the infrared cameras they buy from us. This is probably the technical question that applications engineering gets asked the most.   For the purposes of this application note, we define the spectral response as the relative spectral response (RSR) of the camera as a function of wavelength.

RTools: Radiometric Software Toolkit

Indigo Systems Corporation has released a commercial off-the-shelf (COTS) PC-based software toolkit named RTools. RTools was developed for engineers and scientists to acquire, radiometrically calibrate, analyze, and document data from most high-end digital infrared (IR) focal plane array (FPA) imaging systems. The RTools software toolkit is comprised of several stand-alone modules including RDac for image acquisition and real-time image analysis, RCal for radiometric and thermographic image calibration, REdit for image file archival and maintenance, and RView for image review, reduction, analysis, and report generation.
