The basic goal was to design a multipurpose, multifunctional spectral radiometer system having a lifetime longer than present projections of possible future applications. The basic solution was to use a microprocessoras the Fundamental component of system architecture. Maximum potential was achieved by making use of software coupling to operate the microprocessor both as a controller of analog Functions as well as a digital data processor. Analog control functions presently include operation of spectral filter selection systems, scanning mirrors, optical path selectors, and automatic switching of attenuators and bandpass filters. Data processing is both analog and digital and includes data normalization, signal averaging and equation processing. The paper describes the various design considerations and the selected implementations.
