Paper Abstract

In the past Philips USFA has developed different high performance thermal imaging systems. These systems all use the 8-12 micron window, SPRITE detectors and a 2-dimensional scanning system based on the starrotor. Due to the emphasis on high performance this resulted in high cost for these types of systems. A general relative cost breakdown of these high performance thermal imaging systems will be given: optics, detector and cooling, scanning mechanism, electronics, mechanical housing and display. For all these modules the cost decrease using the 3-5 micron instead of the 8-12 micron window was discussed. A cost/performance analysis will be given comparing the high performance systems with the design of the low cost system. The various design features were discussed, such as: - field of view change with changing F-number: in both fields of view full pupil is used - one scanning mechanism using a drum with 10 tilted facets - electronic correction of scanner distortion - modular design - flexibility. Using this design approach models for different applications can easily be realised. At the exhibition a model developed for use in a light armoured vehicle was shown together with a handheld version for various applications.
