摘要： A display system includes a substrate guided relay and a scanning projector. The scanning projector exhibits a brightness variation on a resonant scanning axis, and the substrate guided relay exhibits a brightness variation along a length of an output coupler. The scanning projector includes a brightness compensation circuit to compensate for both the brightness variation caused by the resonant scanning and the brightness variation along the length of the output coupler.

摘要： Briefly, in accordance with one or more embodiments, an input device may be utilized in conjunction with a scanned beam display or the like, or may be based on the scanning platform as used in a scanned beam display such as a MEMS based scanner. An input event such as illumination of a photodetector or reflection of a scanned beam off of a retroreflector may be correlated with a timing event of the scanning platform such as a refresh signal, or a horizontal and vertical sync signals. The correlation of the timing event may be representative of an X-Y location, and in some embodiments of a Z location, that may be utilized to provide input data back to a host device.

摘要： Briefly, in accordance with one more embodiments, a substrate guided relay comprises a slab guide having an absorbing edge at a first end of the slab guide. An input coupler is disposed on a surface of the slab guide at an angle with respect to a first edge of the slab guide. An output coupler is disposed on the surface at a second end of the slab guide. Light rays that enter the slab guide toward the first end are absorbed by the absorbing edge, and light rays that enter the slab guide toward the output coupler exit the slab guide via the output coupler. The absorbing edge on the first edge of the slab guide allows the input coupler to be placed on the slab guide without regard to alignment of the input coupler with the first end of the slab guide.

摘要： In imaging system (100), a spatial light modulator (101) is configured to produce images (102) by scanning a plurality light beams (104,105,106). A first optical element (107) is configured to cause the plurality of light beams to converge along an optical path (114) defined between the first optical element and the spatial light modulator. A second optical element (115) is disposed between the spatial light modulator and an output of the imaging system. The first optical element and the spatial light modulator are arranged such that an image plane (117) is created between the spatial light modulator and the second optical element. The second optical element is configured to collect the diverging light (118) from the image plane and collimate it. The second optical element then delivers the collimated light to a pupil (120) on the other side of the second optical element relative to the spatial light modulator.

摘要： Briefly, in accordance with one more embodiments, a substrate guided relay for a photonics module includes a slab guide having a first end and a second end, and a first surface and a second surface. An input coupler disposed at the first end of the slab guide at an interface between the input coupler and the slab guide receives an input beam and feeds the input beam into the slab guide which generates multiple copies of the input beam. An output coupler disposed on the first surface of the slab guide causes the multiple copies of the input beam to exit the slab guide via the output coupler as an output. A homogenizer disposed on the second surface of the slab guide reflects at least some of the multiple copies of the input beam to increase uniformity of the output.

摘要： A MEMS-based projector may be included in various user devices. A selective fold mirror, a MEMS-based projector, and a polarization rotator may be oriented to reflect a beam within the device for external projection. Alternatively, a total internal reflection prism may take the place of a selective fold mirror or a polarization rotator and may reduce the number of necessary components in the user device. Various optical components may be placed in the MEMS-based projector and arranged in different positions to reflect a light beam in a desired direction for external projection. The components that make up the MEMS-based projector may depend on the available footprint in the device and the direction in which the light beam is to be projected. Some optical components may provide multiple functionalities which would otherwise require multiple components and may reduce the size of the projector.
