Patent number: 8355013Abstract: An integrated photonics module may include a selective fold mirror configured to pass at least a portion of emitted light toward the MEMS scanner and reflect scanned light through to a field of view. The selective fold mirror may use beam polarization to select beam passing and reflection. The integrated photonics module may include a beam rotator such as a quarter-wave plate to convert the polarization of the emitted light to a different polarization adapted for passage through the fold mirror. The integrated photonics module may include one or more light detectors.Type: GrantFiled: June 10, 2011Date of Patent: January 15, 2013Assignee: Microvision, Inc.Inventors: Randall B. Sprague, Joshua O. Miller, Margaret K. Brown, Mark O. Freeman, Maarten Niesten, Bin Xue, Christopher A. Wiklof

Patent number: 8294993Abstract: A variable reflectivity notch filter (100), suitable for use with a laser image projection source (1001) is provided. The variable reflectivity notch filter (100) defines a transmission curve (101) having a plurality of reflective peaks (102,103,104) each centered about a predetermined wavelength (105,106,107), which can correspond to output wavelengths from laser sources. Reflective peaks (204) corresponding to wavelengths that change with temperature are configured with wider widths (223) and lesser reflectivities (210) than are other reflective peaks (202,203). To provide enhanced color balance, lasers (821) corresponding to these reflective peaks (204) can be driven at higher output power. Variable reflectivity notch filters (100) are suitable for use in head-up displays as well as other applications.Type: GrantFiled: July 26, 2010Date of Patent: October 23, 2012Assignee: Microvision, Inc.Inventor: Maarten Niesten

Publication number: 20090141244Abstract: 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.Type: ApplicationFiled: January 22, 2009Publication date: June 4, 2009Applicant: Microvision, Inc.Inventors: Joshua O.
