- Abstract
- A survey of the literature on retroreflection has been conducted and information from this survey necessary for the understanding of the phenomenon of retroreflection is summarized. Items included are materials, measurement geometry, quantities to be measured, instrumentation, and methods of calibration. Recommendations are given to evaluate or to write specifications is presented in tabular form. Some prior research and intercomparisons are summarized including the results of a previously unpublished intercomparison using prismatic type retroreflectors. The state-of-measurement-accuracy is inferred from the information presented. A bibliography is included for those who would like to obtain more details.
