The development of a linear diode array detector system for astronomical spectroscopy

Abstract

The work reported in this thesis describes the development of an early linear diode array detector system for use in astronomical spectroscopy, outlines factors rendering such a detector suitable for this field, examines some of the more taxing practical problems encountered in early stages of development and, drawing upon these factors and attempted resolutions of the purported initial snags, continues with a look at a recent version and work accomplished with it. In attempting to cover these areas in the development, the description will draw as heavily upon actual laboratory tests carried out as upon the observational fieldwork at both the RGO and the Wise Observatory, partially because of the fact that detailed analysis of the limited data collected is not one of this work's central concerns. As it was necessary to construct a complete working system fairly quickly, the approach adapted and described in detail in what follows may be recognizably far from optimal. Experience gained and various techniques developed could, however, lead to significant improvements in future systems. Therefore, such techniques as they emerge during the early stages are outlined throughout the account as they seem to be one of the more valuable contributions of the project.
