Abstract : Optimization of satellite pictures by standardizing the range of reflective density is accomplished by the use of a dynamic signal simulator which sweeps the amplitude of a 2400 Hz signal from 4 to -32 dBm providing a direct display of the crater tube current versus signal amplitude on an oscilloscope. The time required for setting up the standardizing function is reduced to a few minutes per day. Use of these techniques permits quantitative temperature measurements to be made from DRIR pictures with a densitometer. (Author)
