摘要： Aspects for active alignment for assembling optical imaging systems are described herein. As an example, the aspects may include aligning an optical detector with an optical component. The optical component is configured to alter a direction of one or more light beams emitted from an image displayed by an optical engine. The aspects may further include detecting, by the optical detector, a virtual image generated by the one or more light beams emitted by the optical engine; and adjusting, by a multi-axis controller, an optical path of the one or more light beams based on one or more parameters of the virtual image collected by the optical detector.

摘要： An imaging display system in the field of augmented reality technology comprises a waveguide structure (14) disposed on an outer surface of an exit surface (7) of a polarization beam splitter (3) of an optical engine module (A). The waveguide structure is tubular. One end (15) of the waveguide structure is connected to the exit surface and together with the exit surface forms a preset angle (α). The other end of the waveguide structure is a free end. The imaging display system expands an eye motion box (EMB) by means of the waveguide structure. The preset angle formed between the waveguide structure and the exit surface causes light (22) incident on the waveguide structure to undergo total internal reflection inside the waveguide structure. The waveguide structure further comprises a plurality of semi-transmissive and semi-reflective lenses (18) disposed obliquely in order inside the waveguide structure, and the light incident into the waveguide structure is reflected on the surface of each of the lenses such that the light is uniformly released into viewer's eyes. The imaging display system can realize more compact applications in AR optical systems and provide a larger field of view (FOV) and eye motion box for users.

摘要： A robot voice direction-seeking turning system and method. The robot voice direction-seeking turning system employs a voice activity detection unit (1) that detects a received voice signal to determine whether or not a voice signal transmitted by a user (S2) is present; a direction-seeking angle for the voice signal is calculated by a voice direction-seeking unit (3), and a voice direction-seeking turning unit (4) is employed to drive a robot to turn towards the direction of the sound source of the voice signal on the basis of a direction-seeking angle (S4). Employment of the robot voice direction-seeking turning method allows accurate acquisition of a valid voice signal transmitted by the user, thus increasing signal-to-noise ratio and the accuracy of voice recognition.

摘要： The present invention provides for a display device, which is applied to rear projection system. The device includes a screen, which is curved with incident rays penetrating into a concave side of the screen, and then being transmitted by the screen, to form parallel rays to be emitted out from the convex side of the screen. The device also includes a projecting unit, configured to project rays of an image to the screen, the image including a valid area and an invalid area. The device yet further includes a covering plank, located between the screen and the projecting unit, and configured to cover the invalid area of the image for getting the light of the valid area of the image emitted by the projecting unit to project to the screen.
