(ii) a corrugated clear polymer sheet in contact with or in close proximity without being in contact with a protective glass plate or touch panel placed above an image display screen;

(iii) two corrugated clear polymer sheets placed in contact on top of each other with the corrugations being in parallel to each other sheet and the image display screen being in close proximity or in contact with either clear polymer sheet; or

(iv) 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.

2. The mobile phone/device case or cover of claim 1 , wherein the 3D camera further comprises two objective lenses ( 5610 , 5610 ) 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.

3. The mobile phone/device case or cover of claim 1 , wherein the V-shaped optical component comprises four prisms ( 6020 , 6030 , 6040 , 6050 ) placed in two groups of two, where in a given group, light entering into one prism is reflected into the second prism due to total internal reflection at the first prism and the light entering the second prism is reflected due to total internal reflection at the second prism, on the image sensor, forming side-by-side images on the image sensor.

4. The mobile phone/device case or cover of claim 2 , wherein the V-shaped optical component comprises four prisms ( 6020 , 6030 , 6040 , 6050 ) placed in two groups of two, where in a given group, light entering into one prism is reflected into the second prism due to total internal reflection at the first prism and the light entering the second prism is reflected due to total internal reflection at the second prism, on the image sensor, forming side-by-side images on the image sensor.

5. The mobile phone/device case or cover of claim 2 , wherein the two objective lenses are placed at a distance from the V-shaped optical component.

6. The mobile phone/device case or cover of claim 2 , wherein the two objective lenses are placed in contact with the V-shaped optical component.

7. The mobile phone/device case or cover of claim 4 , wherein the two objective lenses are placed at a distance from the V-shaped optical component.

8. The mobile phone/device case or cover of claim 4 , wherein the two objective lenses are placed in contact with the V-shaped optical component.

9. The mobile phone/device case or cover of claim 1 , wherein the 3D camera is rotatable in multiple axes, allowing the 3D camera to be used as main camera and a selfie camera.

10. The mobile phone/device case or cover of claim 1 , wherein the 3D camera is detachable from the mobile phone/device case or cover, allowing the 3D camera to be used as a remote-controlled camera.

11. The mobile phone/device case or cover of claim 1 , wherein the 3D viewer sheet is in a form selected from the group consisting of a sticker, a peel-able sticker, and a flip cover.

12. The mobile phone/device case or cover of claim 1 , wherein the 3D camera is controlled by an application which operates in the mobile phone/device.

13. The mobile phone/device case or cover of claim 1 , wherein the 3D viewer sheet is placed on top of a display screen of the mobile phone/device, allowing 3D viewing on the mobile phone/device, without the use of special glasses.

14. The mobile phone/device case or cover of claim 1 , wherein the corrugated clear polymer sheets are selected from the group consisting of lenticular sheets, diamond sheets, prism sheets, and combinations thereof.

15. The mobile phone/device case or cover of claim 1 , 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.

16. The mobile phone/device case or cover of claim 1 , wherein the 3D viewer sheet does not require electricity to function.

17. 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; and

wherein the 3D viewer sheet consists of:

(i) a corrugated clear polymer sheet in contact with or in close proximity without being in contact with an image display screen;

(ii) a corrugated clear polymer sheet in contact with or in close proximity without being in contact with a protective glass plate or touch panel placed above an image display screen;

(iii) two corrugated clear polymer sheets placed in contact on top of each other with the corrugations being in parallel to each other sheet and the image display screen being in close proximity or in contact with either clear polymer sheet; or

(iv) 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.
