Underwater high-energy variable light field adjustment control device

Abstract

The invention discloses an underwater high-energy variable light field adjustment control device, which comprises a synchronous controller, an LED light source shore driving control cabinet, illumination shore data acquisition equipment, underwater light field illumination measurement equipment, a lifting mechanism and a mounting frame; underwater reflectors are symmetrically arranged at the lowerpart of the mounting frame, and a sliding rail is arranged at the upper part of the mounting frame; a plurality of sets of lighting devices are installed on the sliding rail and electrically connected with the synchronous controller and the LED light source shore driving control cabinet, and the underwater light field illuminance measurement equipment is electrically connected with the illumination shore data acquisition equipment. According to the invention, a uniform light field with a variable irradiation area can be rapidly built underwater according to test requirements, so that high-intensity continuous illumination can be carried out within the integral time of the high-speed camera; and meanwhile, underwater uniform object space illuminance not less than 5000 Lux can be provided for full-frame clear imaging of the underwater high-speed camera under the conditions of different underwater depths and different object distances, and accurate processing of an underwater high-speedmoving target trajectory parameter optical imaging mode is realized.

Description

Technical field [0001] The present invention relates to an underwater high energy variable light field adjustment control device, mainly used in underwater ultra-high-speed moving target imaging high energy active lighting, belonging to underwater lighting technology. Background technique [0002] In general, ultra-high-speed shooting ballistic parameters measurement is performed in the closed water target trail, and for photoelectric imaging devices, the light is the necessary condition of imaging, especially in the safety start, completely Space-enclosed ultra-high-speed water target, high-speed imaging system requires exposure within 0.02 ms integration time, in consideration of the shooting spacing is generally around 4 to 5 meters, due to a strong absorption and scattering effect of the water body to the optical wave, resulting in The light is severely attenuated when the light is spread in the water, but it must be guaranteed to be controlled above 5000LUX, and can form the...

AI Technical Summary

Problems solved by technology

Ordinary light sources cannot be adjusted due to the fixed position, depth and beam angle of the light field, and cannot be adjusted according to different test conditions, under different navigation depths and different object distances, at the moment when the shutter of the high-speed camera is opened is The ultra-high-speed moving target provides object-side illumination that can complete clear imaging
