Calibration method for attenuator piece used in calibrating a transmittance visibility meter
Aiming at the method of indoor calibration of a transmission visibility meter has not been established; a new calibration method by measuring the luminous transmittance of attenuator piece was established. Based on the high homogeneity stability lighting and the multi-spectral transmittance analysis...
