Description
Technical field
The invention belongs to laser illuminator technical fields, especially relate to a kind of for underground distance gated detection imaging
Laser illuminator.
Background technology
China possesses 3,000,000 square kilometres of territorial waters, and the national economy to China is explored at deep-sea, and scientific development has important
Meaning.The 19th meeting of 26 days 2 months the 12nd Standing Committees of the National People's Congress in 2016 passes through《China
People's republic's deep seafloor region resource exploration and development method》, it is intended to the exploration of specification deep seafloor region resource, development activities,
Deep-sea scientific and technical research, resource investigation are promoted, is protected the marine environment, promotes deep seafloor region resource sustainable use, is
China carries out deep-sea exploration and development and provides important legal basis, while sea floor exploration has also been increased to consequence.
The raising of status and the development of deep-sea survey platform, deep-sea underwater exploration equipment and instrument are explored with deep-sea
Research and development, will become various countries research and development emphasis.Wherein seabed underwater visual detection imaging equipment and instrument are most important
One of underwater exploration equipment researches and develops the deep-sea undersea detection imaging device with independent intellectual property right, is filled to China's deep-sea detecting
Standby development, deep-sea exploration, the development of undersea detection engineering, has great importance.
Since underwater visibility is relatively low, various material composition complex dielectrics in water, commonly detection observation in air waterborne
Imaging means especially deep-sea and are not suitable under water.Usual undersea detection imaging technique is divided into sonar contact imaging technique and photoelectricity
Detection imaging technology two major classes.
Sonar be it is a kind of utilizing the underwater propagation characteristic of sound wave, pass through electroacoustic conversion and information processing, complete underwater visit
Survey the electronic equipment with communication task.Due to being distributed by Seawater, the complex environments factor such as ocean temperature, salinity and hydraulic pressure
Influence, the spread speed of sound wave in the seawater changes greatly, and causes the direction of sonar detection, ranging equally accurate error larger；
Many Complex Noises of generally existing in marine environment, the sound and ocean medium itself that such as various marine organisms send out move hair
The sound gone out causes very big interference, rate of false alarm higher sonar detection；Sonar can be used for using sound wave to remote mesh
Target captures detection, and is identified to the big target of distance in hundreds of meters and is imaged roughly, but to small mesh in tens meters of short distances
Mark is difficult to be identified and formed intuitive high-resolution image.Based on above some reasons, short distance small target detection with
High-resolution imaging field is not suitable for using sonar contact system.
In order to fill up the blank that sonar contact technology is intuitively imaged in short distance small target detection and high-resolution, Ren Menkai
Send out underwater photodetection imaging device.
Underwater photodetection imaging technique is to utilize advanced light source and picture pick-up device, at deep-sea under water directly to target
Carry out the technology of detection illumination imaging.It is mainly the following mode：Ordinary light source illuminates detection imaging, low-light level imaging, laser
Illuminate detection imaging.Using photodetection imaging technique, can obtain that sonar detection is difficult to realize to underwater tens meters of distances
High-precision ranging, positioning and the high-resolution real time imagery of interior target, especially Small object such as submarine mine, fish etc. and identification
Effect, increasingly important role is played in field of detecting under water.
Laser has many advantages, such as that monochromaticjty is good, and brightness is high, technologies, the feelings that can be constant in mean power such as modulates by Q
Under condition, by extremely short pulsewidth, very high peak and exported in the form of controllable continuous impulse, propagate it is more remote, therefore using swashing
The technology that light carries out undersea detection illumination imaging is current research hot spot.
But since particulate matter is more in seawater, a large amount of rear orientation light is usually will produce between target and light source, makes to swash
The visibility of optical illumination detection imaging is extremely restricted, and image definition declines to a great extent as distance increases.For maximum journey
Degree reduces rear orientation light to be influenced caused by imaging, and what is usually utilized at present is range gating laser acquisition imaging technique.
Rangerate-gate technique is to separate different distance using pulse laser and ICCD gating video cameras with the priority of time
On scattering light and target reflected light, so that video camera is just opened in the reflected laser pulse arrival of observed target
Shutter works and is imaged.
Such method is very strong to solving the problems, such as the back scattering caused by the suspended particulate in seawater.The distance of system point
Resolution is determined by laser pulse width and detector storbing gate width, if gate width and laser pulse width are all very
It is narrow so that the reflected light of only target proximity gets to video camera, then the signal-to-noise ratio of echo-signal can be greatly improved.
Due to seawater through window wavelength in 430nm~570nm, that is, blue light arrives yellowish green optical band, underwater laser photograph
This wave band of laser of bright generally use is as light source.Neodymium-doped yttrium-aluminum garnet Nd:YAG 532nm pulse lasers have operation steady
Calmly, the advantages that pulse width is relatively narrow, peak power is high, compact-sized, service life is long, easy to maintain, therefore narrow spaces
532nm pulse lasers are the optimal selections currently as underground distance gated detection imaging device illumination light source.
Since the imaging system noise using rangerate-gate technique exploitation is relatively high, resolution ratio is higher, and image-forming range is farther out.
Undersea detection imaging technique based on rangerate-gate technique, it has also become domestic and international undersea detection technical research hot spot.The country has
Underground distance gated detection imaging technology is studied by colleges and universities and research institute, but there are no matured product.
Therefore there is an urgent need for a kind of novel technical solutions to solve the problems, such as this in the prior art.
