Structures for algorithms for automating LDA measurements

摘要

Abstract: With the interface of simple and cheap micro-computers, even low- cost LDA hardware can be made to produce very high quality and large sets of reliable data. With such interfaces, many of the operator demanding tasks of LDA instrument setting and data collection can be automated in a manner approaching an expert system. In this paper, the structure plans of three software routines are presented as elementary modules for such a system. They would suit a LDA signal processing system based on Frequency Tracking. With proper implementation of the ideas presented here, the computer can help establish a non-ambiguous velocity sign convention, optimize the amount of frequency shift, tune the Tracker and automatically collect data.!6
