Abstract

A system for providing a three-dimensional effect include a display that generates emitted light having a first characteristic; a selective light filter that passes or reflects the emitted light based on the first characteristic; a physical prop at least partially positioned between the selective light filter and a viewing location, wherein incident light from the viewing location is reflected by the physical prop and the selective light filter based on a second characteristic of the incident light.

First claim

What is claimed is:

1 . A system for providing a three-dimensional effect comprising:
a display that generates emitted light having a first characteristic; a selective light filter that passes or reflects the emitted light based on the first characteristic; a physical prop at least partially positioned between the selective light filter and a viewing location, wherein incident light from the viewing location is reflected by the physical prop and the selective light filter based on a second characteristic of the incident light.

2 . The system of claim 1 , wherein the first characteristic comprises one or more of a polarization or a wavelength of the emitted light.

3 . The system of claim 1 , wherein the second characteristic comprises a random polarization of the incident light.

4 . The system of claim 2 , wherein the first characteristic comprises the polarization of the emitted light, and the polarization comprises linear or circular polarization.

5 . The system of claim 4 , wherein the polarization comprises the linear polarization, and the linear polarization comprises vertical or horizontal polarization.

6 . The system of claim 1 , wherein the selective light filter passes the emitted light when the first characteristic comprises a same polarization orientation as a polarization orientation of the selective light filter.

7 . The system of claim 1 , wherein the selective light filter comprises a polarization selective mirror.

8 . The system of claim 1 , wherein the emitted light passes through the selective light filter substantially unattenuated.

9 . The system of claim 2 , wherein the first characteristic comprises the wavelength of the emitted light, and the selective light filter passes the emitted light when the wavelength of the emitted light is in one or more spectral peaks.

10 . The system of claim 9 , wherein the incident light comprises broad-spectrum light and the second characteristic of the incident light comprises a removal of one or more spectral notches from the broad-spectrum light.

11 . The system of claim 10 , wherein a range of wavelengths of the one or more spectral peaks corresponds to a range of wavelengths of respective spectral notches of the one or more spectral notches.

12 . The system of claim 1 , wherein the selective light filter comprises a wavelength selective mirror.

13 . The system of claim 12 , wherein the wavelength selective mirror comprises a Bragg grating.

14 . The system of claim 1 , further comprising a first polarization element disposed between the display and the selective light filter.

15 . The system of claim 14 , wherein the first polarization element comprises a combined half wave element and quarter wave element.

16 . The system of claim 14 , further comprising a second polarization element disposed between the selective light filter and the viewing location.

17 . The system of claim 16 , wherein the second polarization element comprises a circular polarizer configured to cancel reflected light from the viewing location.

18 . A method for providing a three-dimensional effect comprising:
generating, via a display, emitted light having a first characteristic; passing or reflecting the emitted light, via a selective light filter, based on the first characteristic; providing a physical prop at least partially positioned between the selective light filter and a viewing location, wherein incident light from the viewing location is reflected by the physical prop and the selective light filter based on a second characteristic of the incident light.

19 . The method of claim 18 , wherein the first characteristic comprises one or more of a polarization or a wavelength of the emitted light.

20 . The method of claim 18 , further comprising passing the emitted light, via the selective light filter, when the first characteristic comprises a same polarization orientation as a polarization orientation of the selective light filter.
