Description

Wireless remote control location double grating imager

Technical field

The utility model relates to a kind of optical diffraction imaging experimental instrument, and particularly a kind of accurately the movement by the wireless remote control optical element realizes that the viewing optics element is to the experimental apparatus of the de-dispersion imaging phenomenon of object and measurement correlation parameter.

Background technology

(Chinese science G collects 2006 to existing paper " grating converge spectral characteristic and double gratings imaging effect ", 36 (5): 556 ~ 560) discussed a kind of method that realizes observing around barrier image, the method utilizes two gratings to form an imaging system, when the thing light wave dispersion behind the first grating diffraction of (also claiming the dispersion grating) from the different wave length of object is thing spectrum ripples at different levels, when certain the order diffraction light that makes wherein certain grade of thing spectrum ripple enter the second sheet gration (also claiming to converge the spectrum grating) and satisfy this grating converges spectral conditions, behind the second sheet gration, will obtain converging the spectrum light beam, therefrom can observe the original image of De-dispersion, this is the described double gratings imaging effect of this article.This imaging optical path has an outstanding feature: imaging optical path is "the" shape, thereby can realize " seeing thing around barrier ".The placement of two gratings and observing object is also out-of-line, particularly the second sheet gration must be arranged in certain order diffraction light path of first grating, and optical diffraction not at the same level has different angle of diffraction, when seeking the ad-hoc location of imaging, the second sheet gration needs to move along first grating order diffraction light path, and this mobile route is the skew lines on plane.

This imaging mode is novel unique, is worth further investigation.This imaging process takes full advantage of the grating diffration characteristic, comprises the dispersion characteristics of grating and converges the light spectrum image-forming characteristic, has reflected typical diffraction phenomena, has obvious teaching significance.No matter but be scientific research or teaching, observation to this phenomenon all needs special instrument with research, for this reason, Guangxi University is according to patented technology " the diffracting imaging integrated test instrument " (patent No.: 02290557.X) developed special " double grating diffraction imager ", and the new experiment that the undergraduate has offered the double grating imaging (seen paper " double grating diffraction imager development with use ", experimental technique and management, the 9th phase of 2011, the 28 volumes: 57-59).Location in this double grating diffraction imager during two grating images is mobile at cross track by its bearing, and this cross track is finished in that vertical with it long rails is mobile simultaneously.

Yet, find by using practice, the use of existing double grating diffraction imager is also inconvenient, Main Problems is: the second sheet gration of imaging needs to move along first grating order diffraction light path, this optical diffraction is the skew lines that is positioned at the plane that certain angle is arranged with horizontal or long rails, because grating running fix is mobile at cross track by its bearing in this instrument, this cross track moves and forms at vertical with it long rails simultaneously, therefore need in moving process, keep laterally with the translational speed ratio is consistent longitudinally, this is for being difficult for controlling by manually operated double grating diffraction imager, inconvenience make the second sheet gration all the time along this specific plane skew lines direction move and the time skew arranged, the deviation of stop position even surpass 10% in experiment, grating positioning is inaccurate, also out of true of manual adjustments corner when grating need to rotate, workload is large and conventional efficient is low.

In existing pertinent instruments design, a kind of " double grating imaging instrument " (utility model patent in addition, the patent No. is CN 200720083179.7), although this constructional device can be realized the second sheet gration and move along skew lines, can realize observing the double grating imaging, but the problem that this scope exists is: the coordinate position of grating is difficult for determining that this instrument only is convenient to observe phenomena and is not easy to measurement data, and manual adjustments determines the inconvenient operation of guide rail position, locates inaccurate.

In sum, existing diffraction imaging experimental apparatus exists because the manual operation moving grating causes conventional efficient, problem that precision is lower.In addition, control signal wire and power lead use flexible circuit conductor if change into automatically controlled, although the method has higher stability and reliability, but because optical grating diffraction Image-forming instrument limited space, wiring is inconvenient, and is subject to the restriction of the motion parts structure of experimental provision own, and the installation of flexible circuit conductor can't be found suitable position and method and cause serving inconvenience to being with of experiment, block such as flexible circuit conductor passive movement part-structure in the experiment, what impact was tested carries out smoothly.Therefore realizing the wireless remote control operation of experimental facilities, improve conventional efficient and precision, is innovative goals of the present utility model.
