Miniaturization design of optical concealment depth measuring system
To guarantee the demand of an underwater vehicle in sailing for the optical concealment in the visible light band and to measure the optical concealment depth of the underwater vehicle in real time, a miniature optical concealment depth measuring system for the visible light band was designed. Due to a model for optical concealment depth, the measuring methods for seawater upward irradiance, seawater downwelling irradiance, the diffuse attenuation coefficient of sea water, and sea water body attenuation coefficient were designed optimally. After optimization, the system has 21 measuring channels with the measurement spectral range from 390 nm to 667 nm, and working depth up to 50 m. A test on the sea was performed, and the test results show that there is an exposure window in the visible light range of 520-560 nm for the underwater vehicle under good weather conditions, meanwhile, the optical concealment depth of the underwater model with a feature length of 0.75 m is 3.5 m. The test results indicate that the miniaturization design of the optical concealment depth measuring system realizes the measurement of the optical concealment depth in the visible light band. The measuring device has advantages on small size and light weight and the system is stable for carrying on the underwater vehicle and provides theoretical and technical supports for the design of the optical concealment depth measuring system which can be independently lifted.
