Abstract
This paper describes the making method of reference reflectance panels in the case of field observation. We discussed examinations of coating materials and painting methods in order to define the making method of reference panels. As for the quality of our produced reference panel, we carried out the bidirectional reflectance factor (BRF) measurement referred to the calibrated standard panel and the bidirectional reflectance distribution function (BRDF) calibration for the reference panel. The characteristic of our produced reference panel was confirmed to have almost same as the standard panel through our experiments.
