Abstract: Interactive projection apparatus, with apparatus for projecting an image toward a screen and apparatus for capturing a reflection from an object touching a point adjacent the screen. The capturing apparatus includes: (1) a curved mirror for receiving light representing the reflection; (2) at least one lens to which the curved mirror reflects light representing the reflection; and (3) a camera for receiving light representing the reflection from the at least one lens.

Abstract: An example device includes a screen, a first light source configured to emit a first light at a first angle during a first time period and a second light source configured to emit a second light at a second angle during a second time period. The second angle is different than the first angle. The second time period is different than the first time period. The device includes a spatial light modulator configured to provide a first view of digital content based on the first angle of the first light emitted during the first time period and a second view of the digital content based on the second angle of the second light emitted during the second time period and projection optics configured to project the first view and the second view for presentation via the screen.

Abstract: Described examples a three-dimensional printer includes a vat having a transparent bottom, the vat configured to contain a photo-polymerizing resin and a lift plate movably positioned within the vat. The three-dimensional printer also includes an optical device configured to project a pattern of light through the transparent bottom. The optical device includes a light source configured to provide light at a light source output and a light integrator configured to provide divergent light at a light integrator output responsive to the light at the light source output. The optical device also includes projection optics configured to project projection output light at an optics output through the transparent bottom responsive to a modulated light at the optics input and a spatial light modulator configured to provide the modulated light responsive to the divergent light.

Abstract: Described examples include a projection system having a light source. The projection system also has a light integrator having an output face, the light integrator configured to receive an output of the light source, wherein a length of the light integrator is less than at least one diametric measurement of the output face of the light integrator. The projection system also has a spatial light modulator and focusing optics configured to receive a light output of the light integrator and configured to focus the light output of the light integrator onto the spatial light modulator. The projection system also has projection optics configured to project modulated light from the spatial light modulator.
