Description
Technical field
The present invention relates to a kind of precision positioning device, relate in particular to a kind of simulation target locating device for laser fusion target chamber diagnostic device.
Background technology
Laser fusion is a kind of artificial controllable nuclear fusion generally adopting at present, and it all has very great Research Significance on civilian and military: for the mankind explore a kind of inexhaustible Clear nuclear energy source; Be used for developing nuclear weapon, the development high energy laser weapon of " totally " (without radiocontamination); Part substitutes nuclear tests.
Therefore, laser fusion is subject to the great attention of each nuclear power of the world, and since 20 century 70 second half, the states such as Russia, U.S., day, method, China and British start the development of high-power laser driver in succession.The U.S. maintains the leading position in the research in this field, and in 2009, formally builds up the ultra-large type laser driving apparatus " NIF " that comprises 192 tunnels, and the successfully igniting in 2010; The MLF that France is building comprises 240 road laser; Construction large laser driver is also fermenting in Japan, and plans to complete between 2015-2020 the basic technology research that can be applicable to generating.China has also set up a series of laser driving apparatus (starlight series, God Light serial etc.), and the laser driving apparatus " Shenguang-Ⅲ " of the largest domestic of building at present comprises 48 road laser.
At present, on laser driving apparatus, carry out at home a large amount of Targetings, developed a series of diagnostic device, for diagnosis, the measurement of the various parameters of target practice process.Yet the pellet diameter of experiment use is only 200 microns, various diagnostic devices must accurately aim at so small target when mounted, but concerning a lot of equipment, this is difficult to accomplish.For example X-ray detecting devices, neutron yield detecting devices etc., only just can produce X-ray, neutron in the moment of practicing shooting, and before practicing shooting, equipment cannot be seen target.
The method of sight that current domestic laser fusion target chamber adopts mainly contains: transit aims at, twin-beam aimings that cross, twin-lens aiming.
Transit aim at take " cross delineation line " in transit be benchmark, " target ", " image-forming component ", " detecting element " are adjusted point-blank.On the one hand, the pointing accuracy of transit lower (tens to hundreds of micron) is especially lower for remote object precision; On the other hand, transit has been realized adjusting to a line, distance that but cannot judgment device distance objective.
Twin-beam aim at be the symmetria bilateralis of equipment set up two-beam, by adjusting, make two-beam realize and crossing in the dreamboat position of equipment.When equipment is installed, as long as the joint of two light beams is transferred to " target " position, realized the location and installation of equipment.This method of sight avoided transit aim at cannot judgment device distance objective distance defect, but the restriction due to intersection's spot size, make this method pointing accuracy can very high (not being generally hundreds of micron), and when equipment is installed, " target " target must be withdrawn really, the substitute is one " cooperation screen ", to receive twin-beam, and the accurate installation itself of " cooperation screen " is exactly another difficult problem.
Twin-lens aim at be the symmetria bilateralis of equipment set up two imaging systems, by adjusting, make the joint of the optical axis of two imaging systems just be positioned at ideal " target " position of diagnostic device, and in advance two imaging systems are demarcated at the image point position on CCD target surface separately.When equipment is installed, as long as " target " enters respectively through camera lens imaging point the position that CCD target surface is demarcated in advance, just realized the location and installation of equipment.The precision of this method of sight is also not bery high: for the ease of finding " target " target, the field range of imaging system needs suitably to expand, " target " picture point on CCD target surface is with regard to the very little (target of 200 microns like this, picture on CCD approximately occupies tens pixels), pointing accuracy can only reach tens to tens microns.When high precision aims at, must help to find target by additional large visual field camera lens.
Yet domestic current test is less by pellet size---be typically 200 microns, all diagnostic devices when mounted, all will aim at so small target.But the installation of current diagnosis equipment all exists the problem of a general character, equipment to be arranged on to best diagnostic position accurately very difficult.
