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.

摘要： Briefly, in accordance with one or more embodiments, an operational state of a MEMS device of a scanner system may be determined. In the event it is determined that the MEMS device is possibly operating in an unsafe mode, the laser may be turned off and/or the MEMS device may be shut down. An operational state of the MEMS device may be determined for example by obtaining a MEMS drive voltage sense signal and/or a MEMS drive current sense signal, and a potentially unsafe mode of operation may be identified if one or more of such signals are not at proper values with respect to predetermined threshold values.

摘要： Briefly, in accordance with one or more embodiments, a MEMS device for a scanner system may be driven in a non-resonant mode of operation. The drive signal provided to the MEMS device may be tailored to prevent the MEMS device from exhibiting resonance characteristics and to cause the MEMS device to operate non-resonantly. In one or more embodiments, a filter may be used to tailor the frequency components of the drive signal, for example to sufficiently attenuate frequency components at or near the resonant frequency of the drive signal. A direct current signal may be provided to the MEMS device to provide an offset to scanned light beam for example to provide beam steering, and the sweep range and/or sweep frequency may be adjusted for example to steer the scanning field of view off axis from the user pointing axis.
