ABSTRACT:
Two embodiments of the visibility meter are disclosed. In the first embodiment, light transmitted from the light transmitter and light received by the light receiver is propagated in a conical beam. The beams are so oriented that they include an obtuse angle. In the first embodiment, a partition blocks all direct transmission of light from the light transmitter to the light receiver. In the second embodiment, direct transmission of light from the light transmitter to the light receiver takes place through the partition, but is limited to a predetermined level.
