Method for measuring optical characteristics of movable probe in coating installation, involves measuring intensity of transmitted beam by probe at transmission detector

摘要

The method involves measuring the intensity of the transmitted beam (10) by a probe at a transmission detector (4). The intensity of the reflected beam (11) is measured by a probe at a reflection detector (5). The intensity of a light beam (9) of a light source (3) is measured at the transmission detector without object (2) in light beam.
