Devices and methods for speckle reduction in scanning projectors using birefringence

Devices and methods are described herein that use birefringent elements to reduce speckle. The birefringent elements are angularly separate received laser light into two separated light beams, and then recombine the two angularly separated light beams. At least one scanning mirror is configured to reflect the recombined laser light beam,... Microvision Inc

Devices and methods for speckle reduction in scanning projectors

Devices and methods are described herein that use a first solid figure element, a polarizing beam splitter, and a second solid figure element to reduce speckle in projected images. Specifically, laser light is generated and split into two portions having orthogonal polarizations. The first portion of laser light is internally... Microvision Inc

Optical steering of component wavelengths of a multi-wavelength beam to enable interactivity

Briefly, in accordance with one or more embodiments, an information handling system comprises a scanning system to scan one or more component wavelength beams into a combined multi-component beam in a first field of view, and a redirecting system to redirect one or more of the component wavelength beams into... Microvision Inc

Multi-stripes lasers for laser based projector displays

A scanning projector and method is provided that that uses at least one multi-stripe laser to generate the laser light for the scanned image. Specifically, the multi-stripe laser includes at least a first laser element and a second laser element formed together on a semiconductor die. The first laser element... Microvision Inc

Scanning projector with feedback from border fixture

A scanning projector and method is provided that generates a feedback signal from at least one photodetector. In the scanning projector, a scanning mirror is configured to reflect laser light into an image region and an over scanned region. The at least one photodetector is configured to receive a portion... Microvision Inc

Mems scan controlled keystone and distortion correction

Briefly, in accordance with one or more embodiments, a MEMS scanned beam projector includes a light source to emit a light beam, a scanning platform to redirect the light beam impinging on the platform, and a display controller to control the light source and the scanning platform to cause the... Microvision Inc

System and feedback control in scanning projectors

A scanning projector and method is provided that generates a feedback signal from at least one photodetector. In the scanning projector, a scanning mirror is configured to reflect laser light into an image region and an over scanned region. The at least one photodetector is configured to receive a portion... Microvision Inc

Mixed-mode depth detection

Briefly, in accordance with one or more embodiments, a MEMS laser beam display to implement mixed-mode depth detection comprises an imaging engine to project an image in a field of view of the MEMS laser beam display, a time of flight (TOF) depth detector to determine a distance to a... Microvision Inc

Hybrid data acquisition in scanned beam display

A scanning display system includes hybrid data acquisition. Data can be acquired in a time-of-flight mode, or in a non-time-of-flight mode. Infrared light pulses may be used in both modes. The infrared light pulses may have different characteristics. Time-of-flight data acquisition and non-time-of-flight data acquisition may be used sequentially or... Microvision Inc

Virtual touch overlay on touchscreen for control of secondary display

A device with a touchscreen includes a transparent virtual touch overlay used to modify content on a secondary display. The device may send display content to the secondary display either wired or wirelessly. The secondary display may be separate from the device or integrated in the device. The secondary display... Microvision Inc

Laser beam scanning assisted autofocus

An apparatus with autofocus includes a scanning laser projector to provide autofocus assist. The scanning laser projector may project visible or nonvisible light in contrasting patterns to provide passive autofocus assist. The scanning laser projector may include a time-of-flight determination circuit to measure distances to provide active autofocus assist. Passive... Microvision Inc

Dynamic constancy of brightness or size of projected content in a scanning display system

A scanning projector includes a MEMS device with a scanning mirror that sweeps a beam in two dimensions. Actuating circuits receive scan angle information and provide signal stimulus to the MEMS device to control the amount of mirror deflection on two axes. The scan angle information may be modified to... Microvision Inc
