Parallel Projection: In this type of projection, the lines of sight from the object to the projection plane are parallel to each other. What this means in plain English is that the lines do not converge into the distance. This is quite the opposite of what your eyes see in reality; howev...

and the generator axes of all the lenticules of the panel are to each other and are inclined with respect to said panel face at a common oblique angle such that the lenticule corners of all lenticules of the panel lie in a common plane. ...
at least one surface which diffuses each incident ray, by reflection, into a fan of rays in a vertical plane, such fans then being rotated about vertical axes by rotating the diffusing surface, or being effectively rotated by subdivision into similar fans in vertical planes relatively inclined...
In order to illuminate the DMD, the ray of light must be incident from a direction inclined at a certain angle from the normal of the DMD, as will be apparent from the operation of the micromirror. The micromirror is tilted at an angle of ±10 degrees, and the rotational axis of the ...
in the longitudinal-stripe lenticular lens screen. Therefore, the light transmittance is high although the angle of view can be three-dimensionally widened by the two lenticular lens screens. In addition, since scan lines of an image are blurred by two diffusion planes, Moire becomes inconspicuous...
