The 3D effect is created when your eyes combine the two images. The image above is one type of random dot stereogram, which takes advantage of a chaotic background to allow the mask image to be repeated while still blending in. Notice the illusion of depth, with certain parts of the trike in the foreground and certain parts in the background. Hold the image below close to your eyes and allow your eyes to unfocus slightly until an image pops into view.ĭo you see the tricycle? Once it is in view, you can even move your head slightly to see the 3D image seem to hover in place. The Magic Eye series of books popularized stereograms in the 1990s. This type of stereogram is made simply by repeating images of different widths. (If you cross your eyes instead of allowing them to unfocus, then the gorillas will be in the foreground instead.) If you then slowly move your face further away from the image, the 3D effect is quite vivid. If you hold the image close and allow your eyes to unfocus, the rows of animals should appear to hover at three different depths, with the leopards in the foreground, the parrots in the middle ground, and the gorillas in the background. 2003.Stereograms allow you to see a three-dimensional shape while looking at a two-dimensional image.

We show in a prototype setup that high dynamic range, multispectral, polarization, and light-field imaging can be achieved with our design. As the filters in our design are exchangeable, a reconfiguration for different imaging purposes is possible. A minor modification of the design also allows for aperture sub-sampling and, hence, light-field imaging. Via different optical filters, we can then recover the desired information. Our design is based on a physical copying mechanism that multiplies a sensor image into a number of identical copies that still carry the plenoptic information of interest. We propose a non-permanent add-on that enables plenoptic imaging with standard cameras.
