METHOD OF DETERMINING RADIATION FLUX DENSITY AT VARIABLE RELATIVE ORIENTATION OF PHOTOMETER AND REMOTE RADIATION SOURCE

摘要

Use: the solution of geophysical and other problems, namely for recording density .potoka light from a remote source under conditions accidentally the varying relative orientation of the radiation source and the photometer. SUMMARY OF THE INVENTION: measured incident flux of radiation independent photodetectors, a photodetector is used with two different angular characteristics, which are parallel to the optical axis, the system is calibrated by determining the dependence of the ratio F (w) of the output signals from the photodetectors of the angle between the optical axes, and photodetectors .napravleniem at the source, and then carried out the measurement of the output signals of both photodetectors at their incidence on the test stream is selected from them, the largest absolute value signal of 0, defined l w dissolved angle between the direction of the radiation source and the optical axis of photodetectors depending F (w), after which the calculated radiation flux density according to the magnitude value of 1 ° and the angular characteristics of the photodetector which corresponds to the found angle w.
