Surface temp. distribution measuring system at random angles - has programmed control and two dimensional scan via computer

摘要

The surface temp. distribution measuring system selects random observation angles between zero degrees and ninety degrees without applying any contact to the surface being investigated. The information is requried for ovens etc. The surfaces are controlled to a set programme and scanned in two dimensions. The measuring signals are switched off by converting the details in an electronic computer to a raster image with cartesian coordinates. The switch off can also be affected by programmed controlled changes of the horizontal and vertical image angle of the observation system. The observation system used is pref. a passive infra red scanner. The signals can also be used to drive a recorder.
