Abstract
This paper describes a Dual Waveband Imaging Radiometer (DUWIR) which GEC Avionics have developed for RSRE Malvern and which has now been put into production. This calibrated imager basically provides synchronous, simultaneous imagery in both infrared wavebands, that is pixel by pixel overlay, from a single optical channel. It combines current generation modular FLIR performance with the necessary internal calibrated references to enable it to function as a radiometer, measuring apparent temperatures in both bands. It also has all the necessary radiometric and system status information displayed in graphic form, overlaid on video to permit ease of subsequent analysis of the imagery. It is based on the Class II, UK Thermal Imaging Common Module (TICM) modules (Figure 1), which comprise the six processing cards and power supply module, the scanner module, the detector lens module, the head amplifier module and the motor drive module which form the basis of the UK high performance, indirect view, modular thermal imager. Selected systems contractors can configure a complete imaging system from these modules by adding a suitable housing, telescope, display, controls and cryogen supply. Note that as the Class II system is intrinsically TV compatible, scanning one TR line for every TV line (including interlaced fields) it does not require any additional scan convertor or interpolator.
