INTRODUCTION Knowledge of the spectral responsivity function of photo- electric detectors is a fundamental requirement for many radiometric, photometric and colorimetr
30、ic applications. Instrumentation for the determination of this function has been assembled in a number of institutes. However, in various intercomparisons organized by the CIE and other organizations, unexpectedly large differences were found between the data from the participating laboratories (Bud
31、de and Sanders, 1973; Budde, 1984). The members of CIE Technical Committee TC-2.2 agreed that a CIE Technical Report should be prepared in which spectral responsivity measurements are discussed. This report is based on the knowledge and opinions of the members of the Committee. It represents to some
32、 extent the present status of the subject and therefore is of temporary significance. Future developments may supersede present-day technology and may render some aspects of this report obsolete. Such development is encouraged and this report should not be considered the last word on the measurement
33、 of spectral responsivity functions, thereby inhibiting further work on improving the technology. Instead, it is hoped that periodic reviews of the report will incorporate such new developments and that such revisions will keep this document up to date and useful. 0.1 Purpose of the report The purpo
34、se of this report is to discuss methods and instrumentation for spectral responsivity measurements. It is intended -1- COPYRIGHT International Commission on IlluminationLicensed by Information Handling Services CIE b4 84 9006145 O002692 056 a8 a guide for anyone wishing to assemble, test or modify i
35、nstrumentation for such measurements. There is no ideal scheme or - instrumentation for this purpose; consequently for several aspects, various options are presented. However, strong recommendations are made on certain points and preferred methods are pointed out. Special attention is given to sourc
36、es of errors, diagnostic tests and corrections. It is emphasized that this report does not suggest one universal scheme for spectral responsivity measurements because such a scheme does not appear to be known yet. The underlying purpose of this report is to stimlate a critical judgement of various o
37、ptions in every phase of the development of new instrumentation or of various aspects of existing instrumentation. 0.2 Organization of the report The determination of a spectral responsivity function can be, and is usually, made in two stages: First, the relative spectral responsivity function is de
38、termined by means of a thermal or other reference detector; in the second stage the absolute calibration is performed, usually at one wavelength. Consequently the main body of this report is organized in two parts: Part 1. The determination of the relative spectral responsivity function Part 2. Meth
39、ods for absolute calibration. It is, of course, feasible to combine the two operations in one step if the absolute spectral responsivity function of the -2- COPYRIGHT International Commission on IlluminationLicensed by Information Handling Services CIE b4 84 900bL45 0002693 T2 reference detector is
40、known and certain instrumental conditions are met. However, in many applications only the relative spectral responsivity function is required. On the other hand a simple procedure may be required to verify the absolute calibration of a detector after some period of use. Therefore the division into t
41、he two separate operations appears quite useful and is adopted.
