摘要： A buffer arrangement for providing pixel information in a Lissajous scanning projection system is provided. The projection system includes a memory, a MEMS mirror, a projection unit, and a data unit. The memory includes a projection buffer and a shadow buffer. An incoming stream of pixel information scanned from the MEMS mirror is written to the shadow buffer. The incoming stream of pixel information is forwarded to the projection buffer. The projection buffer forwards the incoming stream of pixel information to the projection unit. The projection unit projects the incoming stream of pixel information based on the Lissajous pattern through a mirror projector trajectory. The shadow buffer and the projection buffer operate at different frequencies.

摘要： An optical sensing device includes a planar substrate and an array of optical transceivers disposed on the planar substrate. Each optical transceiver includes a photodetector, at least one turning mirror having a reflective surface disposed diagonally relative to the substrate, and multiple waveguides disposed parallel to the substrate. The waveguides include a transmit waveguide, which is coupled to convey outgoing light from a coherent light source to the at least one turning mirror for output from the optical transceiver, and a receive waveguide, which is coupled to receive incoming light reflected by the at least one turning mirror and to convey the incoming light to the photodetector.

摘要： Image projection apparatus includes an image generating assembly, which is configured to project a sequence of line images extending in a first direction. A scanning mirror is positioned to receive and to reflect the line images while rotating about a mirror axis parallel to the first direction. A pupil expander has an edge positioned to receive the line images reflected by the scanning mirror and a face extending in a second direction non-parallel to the first direction and to the edge, and which is configured to direct simultaneously through the face multiple, parallel replicas of the expanded line images arrayed along the second direction.

摘要： An active imaging system uses a MEMS Micro-Mirror Array to form and scan an optical beam over a first portion of scene within a first edge region of the field-of-view of the optical receiver in the direction of motion of the imaging system. In addition to tip and tilt control of the mirrors, the MMA may have piston control which can be used to minimize diffraction losses when focusing and scanning the beam, provide wavefront correction or to compensate for path length variations. The MMA may be partitioned into segments to independently form and scan a plurality of optical beams, which may be used to scan the first or different portions of the scene. The different segments may be provided with reflective coatings at different wavelengths to provide for multi-spectral imaging. The different segments may be used to combine multiple optical sources to increase power or provide multi-spectral illumination.

摘要： A lighting device for a motor vehicle includes a first light source for producing visible light and a MEMS scanner in which a single tiltable mirror is integrated. A light spot, which is generated by the lighting device at a distance from the latter, can be moved by a scanning movement of the mirror. A control apparatus is provided in the lighting device and can be used to operate the lighting device in a first mode of operation. The control apparatus is further configured to operate the lighting device in a second mode of operation. Moreover, a sensor apparatus is provided, such that in the second mode of operation, the apparatus detects as sensor data light radiation which originates from the surroundings of the motor vehicle and which is incident on the mirror. The control apparatus carries out object recognition by way of evaluation of the sensor data.

摘要： An optical deflector includes a mirror configured to reflect light; a pair of support portions each having an end connected to the mirror, and configured to support the mirror; first actuators connected to the respective support portions, and configured to deform the support portions so as to cause the mirror to oscillate about a first axis; a movable frame configured to support the first actuators; and second actuators connected to the movable frame and disposed opposite to the first actuators, with the support portions being interposed between the first actuators and the second actuators. The second actuators are not connected to the support portions. The first actuators and the second actuators bend and deform in the same direction.
