Improved Industrial Infrared Spectrophotometers: The Manufacturer's Viewpoint
Volume 7, Number 3 (Aug. 1953) Page 138-144
More than most people, the infrared instrument designer lives in a world of compromise. On the one hand he is asked for faster recording techniques—indeed, even instantaneous presentation—on the other hand he is asked for greater accuracy and precision and increased resolution. These requests are generally incompatible. If the accuracy of measurement is limited as it usually is by random fluctuations in the photoreceiver, then the only easy means by which higher accuracy can be won consists in taking a great deal more time for the measurement so that the random fluctuations may be averaged out. If increased resolution is desired, it too is generally won at sacrifice in scanning time.
