Be understandable that, described multiple micro-scattering point 515 can also be arranged at described second joint face 521, or described first joint face 511 all arranges multiple micro-scattering point 515 with described second joint face 521.
During use, light is projected from the side of described first substrate 100.Particularly, light is injected with the angle of vertical described first substrate 100, straight line is pooled after being refracted through described first substrate 100 and described first lens 300, again through described transition bed 500, be reflected back described transition bed 500 by described second lens 400 and converge to described micro-scattering point 515, through the scattering of described micro-scattering point 515, thus make the image that observer is formed from the light that described first substrate 100 observes projection.And other light are owing to being inject from each different angle, so can not be reflected, directly through described optical glass 10.
Optical glass 10 provided by the invention, described first lens 300, transition bed 500 and the second lens 400 are provided with between described first substrate 100 and second substrate 200, and multiple micro-scattering point 515 is provided with in the middle of transition bed 500, make the light projected by the scattering of described micro-scattering point 515, thus the image that observer is formed from the light that described first substrate 100 observes projection can be made.
Be understandable that, for the person of ordinary skill of the art, other various corresponding change and distortion can be made by technical conceive according to the present invention, and all these change the protection domain that all should belong to the claims in the present invention with distortion.
