Vorrichtung und Meßverfahren zur Bestimmung des Absorptions- und/oder Streuungsgrades eines Mediums
摘要
The invention concerns a device for determining the degree of absorption and/or dispersion of a medium (8), the device comprising a radiation source (1) and a beam detector (10) and the radiation source (1) emitting reference radiation (5) of a given intensity. The beam detector (10) detects the part (7) of the reference radiation (5) which has passed through the medium (8) as well as external radiation (11) and relays a signal (12) corresponding to the intensity of the detected radiation (7, 11) to an evaluation circuit (13). The radiation source (1) emits reference radiation (5) periodically or intermittently.
