Paper Abstract

A model of transmissometer based on a visible diode laser light source is described. The instrument is mainly destined for visibility measurements in foggy and polluted air. It features an integrated construction of transmitter and receiver. The emitted laser beam is reversed to the unit by a remote prism assembly that can be placed several meters away from the instrument. To compensate the instability of both the light source and the detector an internal compensating light path as well as other means were applied. The description of the model has been preceded by the analysis of visibility measurement accuracy.
