Publication number: 20140153001Abstract: An optical scanning device includes a substrate, which is etched to define an array of two or more parallel micromirrors and a support surrounding the micromirrors. Respective spindles connect the micromirrors to the support, thereby defining respective parallel axes of rotation of the micromirrors relative to the support. One or more flexible coupling members are connected to the micromirrors so as to synchronize an oscillation of the micromirrors about the respective axes.Type: ApplicationFiled: March 13, 2013Publication date: June 5, 2014Applicant: PRIMESENSE LTD.Inventor: PRIMESENSE LTD.

Publication number: 20130222239Abstract: A method, including receiving, by a computer, a sequence of signals indicating a motion of a hand of a user within a predefined area, and segmenting the area into multiple regions. Responsively to the signals, a region is identified in which the hand is located, and a mapping ration is assigned to the motion of the hand based on a direction of the motion and the region in which the hand is located. Using the assigned mapping ratio, a cursor on a display is presented responsively to the indicated motion of the hand.Type: ApplicationFiled: February 27, 2013Publication date: August 29, 2013Applicant: PRIMESENSE LTD.Inventor: Primesense Ltd.

Publication number: 20130207970Abstract: Mapping apparatus includes a transmitter, which emits a beam comprising pulses of light, and a scanner, which is configured to scan the beam, within a predefined scan range, over a scene. A receiver receives the light reflected from the scene and to generate an output indicative of a time of flight of the pulses to and from points in the scene. A processor is coupled to control the scanner so as to cause the beam to scan over a selected window within the scan range and to process the output of the receiver so as to generate a 3D map of a part of the scene that is within the selected window.Type: ApplicationFiled: February 14, 2013Publication date: August 15, 2013Applicant: PRIMESENSE LTD.Inventor: PRIMESENSE LTD.

Publication number: 20130206967Abstract: An optoelectronic module includes a micro-optical substrate and a beam transmitter, including a laser die mounted on the micro-optical substrate and configured to emit at least one laser beam along a beam axis. A receiver includes a detector die mounted on the micro-optical substrate and configured to sense light received by the module along a collection axis of the receiver. Beam-combining optics are configured to direct the laser beam and the received light so that the beam axis is aligned with the collection axis outside the module.Type: ApplicationFiled: February 14, 2013Publication date: August 15, 2013Applicant: PRIMESENSE LTD.Inventor: Primesense Ltd.

Publication number: 20130202161Abstract: A method for face detection includes capturing a depth map and an image of a scene and selecting one or more locations in the image to test for presence of human faces. At each selected location, a respective face detection window is defined, having a size that is scaled according to a depth coordinate of the location that is indicated by the depth map. Apart of the image that is contained within each face detection window is processed to determine whether the face detection window contains a human face. Similar methods may also be applied in identifying other object types.Type: ApplicationFiled: January 28, 2013Publication date: August 8, 2013Applicant: PRIMESENSE LTD.Inventor: PRIMESENSE LTD.

Publication number: 20130155195Abstract: A system and method are presented for use in the object reconstruction. The system comprises an illuminating unit, and an imaging unit (see FIG. 1). The illuminating unit comprises a coherent light source and a generator of a random speckle pattern accommodated in the optical path of illuminating light propagating from the light source towards an object, thereby projecting onto the object a coherent random speckle pattern. The imaging unit is configured for detecting a light response of an illuminated region and generating image data. The image data is indicative of the object with the projected speckles pattern and thus indicative of a shift of the pattern in the image of the object relative to a reference image of said pattern. This enables real-time reconstruction of a three-dimensional map of the object.Type: ApplicationFiled: February 11, 2013Publication date: June 20, 2013Applicant: PRIMESENSE LTD.Inventor: Primesense Ltd.

Publication number: 20130147921Abstract: Imaging apparatus includes an illumination assembly, including a plurality of radiation sources and projection optics, which are configured to project radiation from the radiation sources onto different, respective regions of a scene. An imaging assembly includes an image sensor and objective optics configured to form an optical image of the scene on the image sensor, which includes an array of sensor elements arranged in multiple groups, which are triggered by a rolling shutter to capture the radiation from the scene in successive, respective exposure periods from different, respective areas of the scene so as to form an electronic image of the scene. A controller is coupled to actuate the radiation sources sequentially in a pulsed mode so that the illumination assembly illuminates the different, respective areas of the scene in synchronization with the rolling shutter.Type: ApplicationFiled: February 13, 2013Publication date: June 13, 2013Applicant: PRIMESENSE LTD.Inventor: PrimeSense Ltd.

Publication number: 20130136305Abstract: Apparatus (20) for 3D mapping of an object (28) includes an illumination assembly (30), including a coherent light source (32) and a diffuser (33), which are arranged to project a primary speckle pattern on the object. A single image capture assembly (38) is arranged to capture images of the primary speckle pattern on the object from a single, fixed location and angle relative to the illumination assembly. A processor (24) is coupled to process the images of the primary speckle pattern captured at the single, fixed angle so as to derive a 3D map of the object.Type: ApplicationFiled: January 24, 2013Publication date: May 30, 2013Applicant: PRIMESENSE LTD.Inventor: PRIMESENSE LTD.

Publication number: 20130120841Abstract: Optical apparatus includes first and second diffractive optical elements (DOEs) arranged in series to diffract an input beam of radiation. The first DOE is configured to apply to the input beam a pattern with a specified divergence angle, while the second DOE is configured to split the input beam into a matrix of output beams with a specified fan-out angle. The divergence and fan-out angles are chosen so as to project the radiation onto a region in space in multiple adjacent instances of the pattern.Type: ApplicationFiled: January 6, 2013Publication date: May 16, 2013Applicant: PRIMESENSE LTD.Inventor: PRIMESENSE LTD.
