N2 - Recently, an automated system for near real-time measurement of absorption coefficients in liquids and biological tissue was developed. The output of a precision amplifier is presented to the analog interface of a mini-computer and digitized information subsequently processed. A smaller mini-computer is used to control gain, filtering, transducer placement and intensity. This allows real-time processing to a degree sufficient to point to possible anomalies during the course of an experiment. Calibration of the various components of the system has been carried out, and materials of known absorption characteristics measured.
