Embodiment

In order to make those skilled in the art person understand the utility model scheme better, and above-mentioned purpose of the present utility model, feature and advantage can be become apparent more, the utility model is described in further detail below in conjunction with drawings and Examples.

As shown in Figure 1 and Figure 2, a preferred embodiment of the utility model polarisation tester comprises an opaque casing 10, and this casing 10 is nearly cuboid, its antetheca 11 low, rear wall 12 height, and loam cake 13 is the inclined-plane; Be provided with light source 20 and transparent panel 30 in the described casing 10; This light source 20 is arranged on nearly loam cake 13 of casing 10 internal upper parts and rear wall 12 places; One side of this transparent panel 30 is fixed on the rear wall 12 of casing 10, and relative another side is arranged on the bottom half 14, the angle of

transparent panel

30 and 14 one-tenth 30 ° of bottom halves; Casing antetheca 11 is provided with viewport 40, is fixed with picture 16 on transparent panel 30 times, the casing rear wall 12.

In the present embodiment, light sends on the irradiation transparent panel from light source, because transparent panel is reflective to the light generation, therefore, before not putting on polariscope, can't see the content of picture on the rear wall by viewport; After putting on polariscope, polariscope is eliminated the polar biased light of transparent panel reflection, and the reflective disappearance on the transparent panel can the clear pictorial diagram of seeing on the picture.

As shown in Figure 3, Figure 4,, also picture 16 can be placed on bottom half 14, and viewport 40 is arranged on box cover 13 wall 11 places nearby, the angle of

transparent panel

30 and 14 one-tenth 40 ° of bottom halves as further improvement to the foregoing description; Can reach the effect of observation equally.

As Fig. 5, shown in Figure 6, the another preferred embodiment of the utility model polarisation tester comprises an opaque casing 10, and this casing 10 is nearly cuboid, its antetheca 11 low, rear wall 12 height, and loam cake 13 is the inclined-plane; Be provided with light source 20 and transparent panel 30 in the described casing 10, this light source 20 is arranged on the rear wall 12; One side of this transparent panel 30 is fixed on the antetheca 11 of casing 10, and relative another side is arranged on the bottom half 14, the angle of

transparent panel

30 and 14 one-tenth 55 ° of bottom halves; Be parallel to rear wall 12 in the casing 10, also be provided with transparent inverted image plate 15 perpendicular to bottom 14, the bottom of this inverted image plate 15 is fixed on the junction of transparent panel 30 and bottom 14; Box cover 13 nearby wall 11 places is provided with viewport 40; Bottom half 14 is placed with picture 16.

In the present embodiment, light sends from light source, sees through on the inverted image plate irradiation transparent panel, produces inverted image on transparent panel, therefore, before not putting on polariscope, can't see the content of picture under the transparent panel clearly by viewport; After putting on polariscope, polariscope is eliminated the polar biased light of inverted image on the transparent panel, and the inverted image on the transparent panel disappears, can the clear pictorial diagram of seeing on the picture.

As Fig. 7, shown in Figure 8, as the further improvement to the foregoing description, light source 20 can be arranged on the nearly rear wall of loam cake 13 inside surfaces 12 places, and light source is provided with a frequency modulated light plate 18 that is fixed on the box cover 13 for 20 times,, the angle of

transparent panel

30 and 14 one-tenth 50 ° of bottom halves; Simultaneously, opaque inverted image plate 15 is arranged on rear wall 12, or rear wall 12 directly is arranged to inverted image plate 15; Light source 20 is subjected to the resistance shelves of frequency modulated light plate 18, can only be on inverted image plate 15 throw light, light to transparent panel 30, and produces inverted image through the reflective projection of inverted image plate 15 on transparent panel 30, make can't clearly see content on 30 times pictures 16 of transparent panel by viewport 40; And after putting on polariscope, the inverted image on the transparent panel disappears, can the clear pictorial diagram of seeing on the picture 16.

The above; it only is the preferable embodiment of the utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
