A System for Sampling, Labeling, and Digital Recording of Optical Measurement Data

Abstract

Optical measurement data generated at the Verona Test Site of RADC must be reduced in a computer to extract the desired parameters. These parameters are: angle-of-arrival, phase-structure function, modulation transfer function, and amplitude scintillation. This report describes a system which processes the raw measurement data and generates digital tape recordings suitable for input to a GE 645 Computer. The system consists of two components. First is an Optical Data Processor (ODP) which reduces the dynamic range required for sampling and recording the raw data, and the storage volume required for the recordings. The second component of the system is software which was written for the PDP-8 computer at the test site.
