Description
Technical field
The utility model relates to a kind of image observation and harvester, relates in particular to a kind of polarized light image observation and harvester.
Background technology
Light is when a certain material, and not because direction of illumination changes, this material optically just has " isotropy ", claims again the single refraction body, such as common gases, liquid and amorphism solid such as the character of light and route; If when light passed through another material, the vibratility of the speed of light, refractive index, absorbability and smooth bark, amplitude etc. were different because direction of illumination has, this material optically then has " anisotropy ", claims again the two-fold beam, such as crystal, fiber etc.
Natural light is a kind of shear wave, by polaroid incident light only is separated into the in one direction light wave of vibration, and this light wave then is called " polarisation " or " polarized light ".The rotatory polarization sheet just can obtain the polarized light of different directions.If two polaroid quadratures are placed, then if the visual field complete darkness is with two parallel placements of polaroid, then maximum by light.Put into crystal between two polaroids, in the situation of quadrature, the visual field is dark, if tested object optically shows as isotropy (single refraction body), thing is observed in rotation in any case, and the visual field still is dark.Contain the birefringence material in the object if be observed, then this part will be luminous, and rotation is observed object, and luminous component performance light and shade changes.Polarizing microscope utilizes this principle just.In rock-mineral determination, jewel evaluation, crystal observation and analysis, fiber observation and analysis, bio-sheet material observation and analysis, use in a large number polarizing microscope.
At present polarizing microscope observation crystalline solid is luminous, during frosting phenomenon, need under cross-polarized light, rotate and be observed object, but be observed object owing to rotated, make the people when the observation luminous component, be difficult for easily memory, statistics variations situation because of change in location.In the computer acquisition graphical analysis, be difficult for same position is carried out registration.
Summary of the invention
The purpose of this utility model provides a kind of polarized light image of mobile testee that do not need to observe and harvester with regard to being in order to address the above problem.
Observation described in the utility model and harvester are achieved through the following technical solutions above-mentioned purpose:
