or (d) two corrugated clear polymer sheets placed in contact on top of each other with the corrugations being not in parallel to each other sheet and the image display screen being in close proximity or in contact with either clear polymer sheet. ### Claim 15 (depends on 14) The mobile phone/device case or cover of claim 14, wherein the corrugated clear polymer sheets are selected from the group consisting of lenticular sheets, diamond sheets, prism sheets, and combinations thereof. ### Claim 16 (depends on 14) The mobile phone/device case or cover of claim 14, wherein the image display screen is a liquid crystal display, a thin film transistor, an organic light emitting diode, or a light emitting diode display. ### Claim 17 (depends on 1) The mobile phone/device case or cover of claim 1, wherein the 3D viewer sheet does not require electricity to function. ### Claim 18 A mobile phone/device case or cover consisting of a 3D camera, realized by integrating or connecting two cameras and a 3D viewer sheet integrated on the phone/device case or cover; wherein the 3D camera comprises: (a) a V-shaped optical component having left and right arms, which act as light guides to guide the light from an object, onto an image sensor, and a focusing lens for focusing an image on the image sensor, where two images are formed of any object in the field of view of the V-shaped optical component; and (b) two objective lenses to collect and focus light from an object and guide the light through the left and right arms of the V-shaped optical component, respectively, wherein the two objective lenses are placed at a distance from the V-shaped optical component; wherein the 3D viewer sheet does not require electricity to function. ### Claim 19 (depends on 18) The mobile phone/device case or cover of claim 18, wherein the 3D viewer sheet consists of: (a) a corrugated clear polymer sheet in contact with or in close proximity without being in contact with an image display screen;
