The demonstration instrument has the following benefits: complex optical phenomenon is amplified effectively and displayed in real time, so as to achieve the aim of simplifying theoretic teaching. By typical jewel interference figure demonstration, and proper operation and use of the polariscope, an effective interference figure is obtained, so that the jewel axiality is accurately judged, and the aim of effectively identifying the jewel is achieved.
Description
Technical field
The utility model relates to the optics teaching field, relates in particular to jewelry professional teaching field.
Background technology
In the conventional identification and detection instrument of jewelry, polariscope at first can be fast, can't harm, effectively detect the photosensitiveness of jewel; Secondly can be to observe the interferogram of jewel by conoscope, thereby accurately judge the jewel axle, in the conventional identification and detection of gem and jade, have important function and significance.
Under the polariscope, the student observes but relatively difficulty for the jewel interferogram, usually need be with jewel conversion different angles, the interferogram position may appear in searching, promptly allow to accurately find the position of jewel interferogram, also may make observed interferogram imperfect, thereby correct judgement conclusion is caused certain obstruction, thereby correct evaluation of gem and jade kind brought difficulty because of problems such as stone cuts, sizes.
Summary of the invention
In order to solve drawbacks such as interferogram is difficult to correct location under the crossed nicols, and the interferogram of formation is imperfect, for correct the evaluation provides effective scientific basis, the utility model that a kind of polariscope conoscopic interference figure demonstrator is provided.
A kind of polariscope conoscopic interference figure demonstrator, the polariscope base that comprises built-in light source, be arranged on the following polaroid on the base, be arranged on the last polaroid on the support of base, described polaroid up and down and last polaroid align, also comprise micro-lens, CCD and display, described micro-lens is positioned at the top of described upward polaroid and links to each other with described CCD, and described display is connected with described CCD.
Illustrate: CCD, English full name: Charge-coupled Device, Chinese full name: charge coupled cell.Can be called ccd image sensor.CCD is a kind of semiconductor devices, can be converted into digital signal to optical image.The small photoactive substance of the last implantation of CCD is called pixel (Pixel).The pixel count that comprises on CCD is many more, and its screen resolution that provides is also just high more.The effect of CCD is just as film, but it is that image pixel is converted to digital signal.The electric capacity that many marshallings are arranged on the CCD can be responded to light, and image is transformed into digital signal.Via the control of external circuit, each little electric capacity can with its with electric charge be given to its adjacent electric capacity.
Preferred described display is connected with high definition CCD by the VGA data line.VGA (Video Graphics Array) is a kind of video transmission standard that IBM released with the PS/2 machine in 1987, has the resolution height, shows advantages such as speed is fast, color is abundant, has obtained using widely in the color monitor field.
As further improvement of the utility model, also comprise the jewel sample holder, described jewel sample holder is between described upper and lower polariscope, by described polariscope base support.
As further improvement of the utility model, described jewel sample holder is rotatable gimbals.
As further improvement of the utility model, also comprise the conoscopic interference ball, described conoscopic interference ball places described going up between polaroid and the testing sample.
The beneficial effects of the utility model are: the optical phenomena of complexity is passed through effectively amplification, real-time exhibition, reach the purpose of simplifying theory teaching.
By typical jewel interferogram demonstration, polariscope is used in proper operation, obtains effective interferogram, thereby accurately judges the jewel axle, reaches the purpose of effective evaluation jewel.
The utility model is chosen by peculiar jewel sample, carries out correct light rate azimuthal orientation according to a jewel photosensitiveness and an axle property, cuts to grind again and makes typical conoscopic interference figure and demonstrate sample.Secondly under cross-polarized light, utilize and interfere ball to form typical interferogram, to form the projection of interferogram image projection by the high definition imaging device, form relatively more directly perceived, distinct image, solved that interferogram is difficult to correct location under the crossed nicols, drawbacks such as the interferogram that forms is imperfect are for correct the evaluation provides effective scientific basis.
