[embodiment]
Below in conjunction with accompanying drawing, the utility model is described in further detail, and the structure of this device and principle are very clearly concerning the people of this specialty.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, the utility model comprises stainless steel montant, lamp box, lithium electricity bag, the polarizer and analyzer, stainless steel montant is arranged at lamp box side, lamp box top embeds the polarizer, stainless steel montant top connects analyzer, analyzer is arranged at lamp box top, sample is placed between analyzer and lamp box, light source is arranged in lamp box, light source levels direction left part is provided with heat shield, heat shield horizontal direction left part is provided with condenser, condenser horizontal direction left part is provided with catoptron, catoptron vertical direction top is provided with the polarizer, polarizer vertical direction top is provided with divergent mirror, divergent mirror vertical direction top is provided with table top mirror.As shown in Figures 2 and 3, analyzer connects base, stainless steel montant top connects deck, through hole is offered in the middle part of deck, draw-in groove is provided with outside through hole, draw-in groove is provided with a snap ring jaggy, and analyzer base rear portion is provided with a taper connection body, and taper connection body and side, analyzer base junction diameter of section are less than opposite side diameter of section.
Wherein light source adopts LED lamp bead, and LED lamp bead connects lithium electricity bag by electric wire, and LED lamp bead outside is provided with light guide plate, and LED lamp bead is arranged on substrate, and substrate posts reflectance coating.
Concrete using method of the present utility model is: start, at this moment the whole visual field will occur black.Sample is placed in measuring platform, and the position that there is stress is bright white, does not have the position of stress to present black, and black same when not putting sample.Wherein, becoming the position of the colors such as blueness, green, redness, is the more concentration zones of stress ratio.When stress ratio is larger, even if rotary sample, the distribution of stress also can not change.Detect not by the impact of principal direction of stress.When light source is dimmed, should charge to 12V lithium electricity bag in advance.
The utility model utilizes polarisation to shake interference of light ratio juris, and natural light is by becoming linearly polarized light after polaroid, and the direction of vibration of linearly polarized light is consistent with the polarization direction of polaroid, and here polaroid plays a part the polarizer.Wherein analyzer (Analyzer)---be used for checking certain a branch of only no polarized light, detection method is by rotatory polarization sheet, observe the change of transmitted intensity, in this way natural light then transmitted intensity do not change, if polarized light transmission light intensity can change.
The light beam sent by light source passes through heat shield, condenser, catoptron, the polarizer becomes plane galvanometer, pass through divergent mirror again, table top mirror projects in tested sample, if this sample has birefringence, linearly polarized light be just decomposed into the mutual out of plumb of direction of vibration ordinary light and non-ordinary light (effect of filter full-wave plate wouldn't be examined here) because of both velocity of propagation different, one fast one slow, after appearing sample, just create an optical path difference, the interference color drawing with stress characteristics that ordinary light and extraordinary ray produce in same plane will be seen finally by analyzer.
