This technical report contains the terminology required for measurements of" luminous intensity distributions. It also summarizes the principles of luminous intensity measurements and the requirements for the photometer heads employed for such measurements. The coordinate systems used for the mea¬surement and representation of luminous intensity distributions are des¬cribed. The types of goniophotometers, possibilities for angle encoding, characteristics of the,photo-electronic system and the acquisition and processing of the data in measurements of luminous.intensity distributions are discussed in detail. Other subjects covered are the power supply, the measuring conditions and the execution, correction and representation of luminous intensity distribution measurements. The various sections contain sufficient data on the required characterization of goniophotometers. The report is based mainly on the Technical Report of CIE Technical Committee TC-2.2 on "Methods of characterizing the performance of radiometers and photometers [l] as well as on CIE publications 24 [2], 27 [3] and 43 [4]. The terminology is largely based on the International Lighting Vocabulary [5].
