Description
Technical field
The invention belongs to field of optical detection, more particularly to a kind of Overruning that can be placed prism and be convenient for dropwise addition REFRACTIVE LIQUID
Seal birefringent mechanism.
Background technique
Utilize surface sweep angle polarisation method GASP(Grazing Angle Surface Polarimetry) measurement tempered glass
When surface stress, measuring principle is:, can be with parallel glass in the thin layer near surface when light is incident on glass surface
The direction on surface runs a small distance, if glass surface does not have stress, light is all-trans with that can generate when critical angle incidence
It penetrates, i.e., light can be propagated along glass surface, and can be returned again with reflection at critical angle.If glass surface has stress, it is incident on glass
The total reflection light on glass surface can generate birefringent under the action of stressor layers, form that two beam polarization directions are orthogonal and propagation side
To different light beams, the bright fringes or dark fringe which is converted into convenient for identification by imaging unit pass through calculating
Interference fringe information is to obtain corresponding glass surface stress value.
Thus, when using above-mentioned principle test tempering glass surface stress information, it is necessary to place glass to be detected
On refracting prisms, need to guarantee that refracting prisms are fixed to ensure that testing result is reliable and stable, in detection process, it is more in practice
Refracting prisms are fixed in prism platform, in addition, being needed in detection process to glass to be measured and refracting edge to improve detection accuracy
A small amount of REFRACTIVE LIQUID is added dropwise so that the two comes into full contact with, one as disclosed in Chinese invention patent 201510638763.3 in the contact surface of mirror
The multiple tempered glass surface stress instrument of kind, which is provided with a kind of automatic liquid-dropping mechanism: defeated including the fluid reservoir being located on outer framework
Pump, dropping liquid bracket, liquid-drop machine and dropping liquid control mechanism are sent, liquid-drop machine is located at one end of dropping liquid bracket, dropping liquid control mechanism control
REFRACTIVE LIQUID in fluid reservoir is transported to liquid-drop machine to realize liquid-auto-dropping by delivery pump processed, although the automatic liquid-dropping mechanism can be real
The function of REFRACTIVE LIQUID is now added dropwise from trend refracting prisms surface, but this dropper is when in use, needs to complete folding first
The dropwise addition of liquid is penetrated, then glass to be measured can be just placed in the refracting prisms surface for being added dropwise and having REFRACTIVE LIQUID, due to detection process
The dropwise addition for needing to wait REFRACTIVE LIQUID causes detection speed slow, and working efficiency is low.And to guarantee that REFRACTIVE LIQUID is from top to bottom added dropwise to
The suitable position of refracting prisms, it is higher to the dropping liquid control mechanism required precision of dropper, thus lead to manufacturing cost height.
