This device is a measuring optical instrument. It uses signal feedback principle to link up the optical path and the electrocircuit into a closed circuit of photoelectric feedback, so that signal-to-noise ratio in photoelectric conversion is largely increased. Meanwhile, dynamic measuring range of the instrument is widened. Requirements of frequency characteristics of photoelectric converter's elements and electric elements are decreased. The device can be widely used in measurements of fluid mechanics fire, meteorology and seas etc. |
