Abstract: A projector includes a semiconductor die including a digital micromirror device; and a first integral optical layer attached to the semiconductor die. The first integral optical layer includes a first optical lens and a first diffractive optical element. A second integral optical layer is attached to the first integral optical layer. The second integral optical layer includes an aperture stop and a second diffractive optical element. A third integral optical layer is attached to the second integral optical layer. The third integral optical layer includes a second optical lens and a light source mount. The semiconductor die, the first integral optical layer, the second integral optical layer and the third integral optical layer are stacked to form an optical path through the first and second diffractive optical elements, reflect off the digital micromirror device, and pass through the first optical lens, the aperture stop and the second lens.

Abstract: In some examples, an apparatus includes a light source. The light source is configured to operate in a first mode by emitting light during a first period of time during which a display screen reflecting the light is substantially opaque. The light source is also configured to operate in a second mode by not emitting light during a second period of time during which the display screen is substantially transparent. The light source is also configured to repeatedly alternate between the first mode and the second mode to create a perception of an image resulting from the display screen reflecting the light being displayed on a transparent screen.

Abstract: An apparatus includes a first prism and a second prism coupled to the first prism, where the first prism faces a first side of the second prism. The apparatus also includes a spatial light modulator (SLM) facing a second side of the second prism and reflective focusing optics facing a third side of the second prism.
