IPC: G02B5/00
Filed: 1989-06-01
Abstract: PURPOSE:To disable and internal observation in a slantingly horizontal and a vertical direction and to enable an observation perpendicular to a window surface without any shield by making the optical material of a rectangular body which is arranged in a medium with an optional refractive index and arranging it in a three-dimensional space which is represented by orthogonal coordinates (x), (y), and (z). CONSTITUTION:A body B consists of a rectangularly sectioned body (b) made of a medium with a refractive index n1 and a rectangularly sectioned body (c) made of a medium having a refractive index n2 different from the refractive index of the body (b). When light beams exit from the medium A having the optional refractive index n0, enters the body B which has the different refractive indexes n1 and n2 and the border surfaces S between the refractive indexes in parallel to a (z) axis, and enter the medium A with the refractive index n0 again, the light beams travel straight if the incidence direction of the light is perpendicular to the xy plane, namely, parallel to the (z) axis. Consequently, the inside can not be seen in a slantingly horizontal and a vertical direction and an internal person when viewing an external scene can see it vertically without any shield.
