Abstract:

The problem of recording and displaying the spatial and temporal intensity distribution of high power carbon dioxide lasers is analysed in terms of information rate, spatial resolution, frame rate, dynamic range and contrast ratio. State-of-the-art infrared detectors, state-of-the-art data processing and data displaying systems as well as possible future technologies are examined as to availability, cost and reliability. The study concludes that an approach using a linear array of pyroelectric detectors, a digital tape recorder, a minicomputer and an CRT display comes close to fulfilling present requirements. Recommendations regarding medium-term research in this area are made.
