A new method of achieving controlled high-speed infrared imaging
is presented, which has made it possible to overcome some of the limitations in current imaging technology, particularly in disposal of high-rate data flow synchronized with the event or object being investigated. This technique is employed to simultaneously capture two geometrically identical images in respective spectral bands for quantitative spectrometric data reduction. The system features 12-bit data processing capability from two pieces of 64 x 128 PtSi monolithic CCD FPA operated in a noninterlaced mode at pixel clock rates of up to 10 MHz by using new electronic units developed in our laboratory. The system consists of an electronic shutter unit, a programmable external trigger controller, a DRAM memory buffer per channel, a single-channel image processor, and a PC-AT loaded with our software package. Its independently adjustable framing rate and exposure period permit up to 1800 frames/s and as short as 20 μs, respectively.
