Fixed mounted infrared 2D and line cameras for industrial non-contact temperature measurement

New uniform camera electronics were developed for different stationary line and 2D infrared cameras for non-contact temperature measurement. The 16bit analog/digital converter used enables a maximum pixel rate of 10 MHz. The electronics are based on a System Of Programmable Chip (SOPC) solution using a PLD with an embedded processor. The ability to reprogram the PLD allows an inexpensive adaptation to different sensor types and various industrial applications. The embedded processor executes the signal processing. In addition, the embedded processor controls and monitors the camera head, monitors the operation of the chopper/shutter motor and internal temperature sensors, and can be used to control a number of functions such as triggering or frame rate. The PC communicates with the microcontroller via an asynchronous interface. The other essential components of the digital signal-processing unit include a serializer, a flash memory and a SRAM. The new 16bit camera electronics have been incorporated into the 2D infrared cameras PYROVIEW 256 with a pyroelectric array (256 x 128 pixel) and PYROVIEW 320 with a microbolometer array (320 x 240 pixel). In addition the newly developed 16bit camera electronics also provide the basis for faster line cameras PYROLINE 256 with pyroelectric arrays of 256 x 1 and HZK 256 with an InGaAs linear array of 256 x 1.
