    Abstract: Particular embodiments relate generally to laser projection systems and, more particularly, to systems and methods of reducing the appearance of speckle in laser projection images. According to one embodiment, a laser projection system comprising a light source and scanning optics is provided. The scanning optics include a plurality of frame generating optics configured to scan the output beam across a given projection surface to generate an image frame. The frame generating actuators are spatially separated such that output beams scanned by the frame generating actuators illuminate each common pixel portion of the image frames at a different incidence angle. The scanning optics also include an actuator selector positioned in an optical path of the output beam and configured to direct the output beam towards a selected one of the plurality of frame generating actuators.

    Abstract: Laser scanner projection systems that reduce the appearance of speckle in a scanned laser image are provided. The laser projection system includes a visible light source having at least one laser, a scanning element and a system controller. The system controller is programmed to generate a scanned laser image. The system further includes a first lens that focuses a scanned output beam onto an intermediate image and a second lens that projects the intermediate image onto a projection surface. A periodic phase mask having a period that is approximately equal to or greater than the beam waist diameter of the scanned output beam is positioned at the intermediate laser image. The period of the periodic phase mask is such that the projection of the scanned output beam jumps progressively from pixel to pixel, thereby reducing speckle contrast in the scanned laser image.

    Abstract: An optical package includes a semiconductor laser, an adjustable mirror and a wavelength conversion device comprising a waveguide portion. The semiconductor laser, adjustable mirror, and wavelength conversion device are oriented to form an optical pathway between an output of the semiconductor laser and an input of the wavelength conversion device. The beam of the semiconductor laser is directed along the optical pathway and onto the adjustable mirror where the beam is reflected by the adjustable mirror onto the waveguide portion of the wavelength conversion device. The adjustable mirror may also be either thermally or mechanically deformable such that, when the adjustable mirror is deformed, the path of the beam along the optical pathway is altered thereby focusing the beam on the waveguide portion of the wavelength conversion device. The adjustable mirror may be adjusted such that the beam of the semiconductor laser is positioned on the waveguide portion of the wavelength conversion device.

    Abstract: An optical package is provided comprising a laser diode, coupling optics, a wavelength conversion device, and a multi-component mounting frame. The coupling optics comprises a first lens component that creates a virtual magnified image V of the waveguide of one of the opposing facets with a magnification factor M1 and a second lens component that creates a focused image of V at the remaining opposing facet with a magnification factor M2. The virtual magnified image V is outside of the interfacial waveguide-to-waveguide optical path of the package and the multi-component mounting frame comprises first and second frame components that independently fix the relative alignment of the first and second lens components. The first and second frame components are secured to each other such that angular misalignment between the first and second frame components originates along a fixation interface H that is outside of the interfacial waveguide-to-waveguide optical path. The virtual magnified image V and the fixation interface H are both positioned on a common side of the coupling optics, either the laser diode side of the coupling optics or the wavelength conversion device side of the coupling optics. Additional embodiments are disclosed and claimed.
