The expansion of the dynamic range of photodetectors in hydrodynamic research using active optical shutters

Abstract

Abstract The implementation of the method expanding the dynamic range of photodetectors in hydrodynamic experiments based on the use of active optical shutters is presented. A method that allows using modern CMOS cameras as optical radiation receivers and laser emitters as illuminators has been developed. The attenuation coefficients of linearly polarized light on the photodetector has been measured. An experimental estimate of the expansion of the dynamic range in terms of the intensity of the received radiation in the presence of background highlights has been made.
