摘要： A head mounted display with wide field of view (WFOV) is disclosed. A conventional small display is used in conjunction with a Beam Steering Mechanism (BSM) to dynamically steer the FOV of the displayed image at a very fast rate to provide an effectively WFOV for immersive visual experience. An electrically actuated switchable Steering Mechanism (SM) is provided within the display projection module that steers the projected image towards different portions of the lens at a fast rate. The steering can be either in one, two or three dimensions. The steering allows for the displayed image to be wider field of view (FOV) to the observer than conventionally projected images that are small fixed FOV. The SM is steered at a high rate so as to be indistinguishable to the human observer. The steering can be controlled in a gaze tracked dynamic, on-demand fashion so as to save power consumed by the display system.

摘要： A beam steering apparatus including a first actuatable micromirror array (AMA) having a pitch, p, adapted to impart a modulation to a wavefront incident on the first AMA by a transition between a first state and a second state, wherein the first AMA has a transition time (T) between the first state and the second state, and at least one light source adapted to provide the incident wavefront having a duration, t, to the first AMA, where t≤T. The AMA may be a MEMS device such as a digital micromirror array. The beam steering apparatus may constitute a portion of LIDAR system.

摘要： An optical system comprising: an optical element having an optical property responsive to an applied signal, a variation of the optical property with the signal exhibiting hysteresis in a first range of values and no hysteresis in a second range of values of the signal; a memory storing data representing a hysteresis curve which indicates the variation of the optical property with increasing and decreasing values of the signal; and a controller which continuously controls the optical property by: generating, based on the stored data, a cyclic signal having a discontinuity in each cycle of the cyclic signal, and setting the discontinuity size in each cycle based on the stored data such that a part of the variation of the optical property with the cyclic signal coincides with a part of the variation represented by the stored data; and applying the cyclic signal to the optical element.

摘要： An image projector includes a spatial light modulator (SLM) with a two dimensional array of pixel elements controllable to modulate a property of light transmitted or reflected by the pixel elements. An illumination arrangement delivers illumination to the SLM. A collimating arrangement collimates illumination from the SLM to generate a collimated image directed to an exit stop. The illumination arrangement is configured to sequentially illuminate regions of the SLM, each corresponding to a multiple pixel elements. A controller synchronously controls the pixel elements and the illumination arrangement so as to project a collimated image with pixel intensities corresponding to a digital image.

摘要： A surveying apparatus has a combined structure of a total station and a laser scanner. The surveying apparatus includes a point cloud data acquiring unit, an abnormal part detecting unit, an abnormal part position acquiring unit, and an automatic sighting controller. The point cloud data acquiring unit acquires first point cloud data and second point cloud data obtained by laser scanning that is performed on an object to be inspected at a time interval. The abnormal part detecting unit calculates a difference between the first and second point cloud data to detect a part of the object to be inspected, at which position information varies, as a detailed-inspection target part. The abnormal part position acquiring unit acquires a position of the detailed-inspection target part. The automatic sighting controller controls to make the total station sight the detailed-inspection target part, based on the position of the detailed-inspection target part.

摘要： A machine vision system comprises a camera configured to generate one or more images of a field of regard of the camera, a lidar system, and a processor. The lidar system includes a laser configured to emit light, where the emitted light is directed toward a region within the field of regard of the camera and a receiver configured to detect light returned from the emitted light. The processor is configured to receive an indication of a location based on the returned light and determine, based on the one or more images generated by the camera, whether the indication of the location is associated with a spurious return.
