An adaptive slant range compensator, suitable for use with an optical mapg system for remote viewing, comprises a logarithmic amplifier which compresses an analog input signal having a wide range of values to a tractable range. An analog-to-digital (A/D) converter converts the compressed signal to a...http://www.google.es/patents/US4270142?utm_source=gb-gplus-sharePatente US4270142 - Adaptive slant range compensator for a remote optical mapping system
