摘要： Various embodiments of a package-on-package optical sensor comprising three distinct different packages are disclosed. The three different packages are combined to form the optical proximity sensor, where the first package is a light emitter package, the second package is a light detector package, and the third package is an integrated circuit package. First and second infrared light pass components are molded or casted atop the light emitter package and the light detector package after they have been mounted atop the integrated circuit package. An infrared light cut component is then molded or casted between and over portions of the light emitter package and the light detector package.

The system includes a part support subsystem including a fixture for supporting a part to be inspected and a head apparatus. The head apparatus includes at least one radiation source for directing a plane of radiation at the part so that the part occludes the plane of radiation to create unobstructed planar portions of the plane of radiation wherein each of the unobstructed planar portions of the plane of radiation contains an amount of radiation which is representative of a respective geometric dimension of the part. The head apparatus also includes at least one receiver module for measuring the amount of radiation present in each of the unobstructed planar portions and a triangulation-based sensor to illuminate the part with a beam of electromagnetic energy to obtain a reflected beam of electromagnetic energy and to sense at least one portion of the reflected beam of electromagnetic energy. The system further includes a movable stage subsystem coupled to the head apparatus for translating the head apparatus relative to the part so that the plane of radiation and the beam of electromagnetic energy linearly scan the part supported by the fixture and a controller for generating control signals to control linear movement of the stage subsystem during the linear scan.

摘要： The present invention discloses a method for saving power consumption of a position sensitive detector used in a smart bathroom product. An infrared light emitting device included in the position sensitive detector has infrared light emitting modes of at least two strengths. The position sensitive detector determines the emitting strength to be adopted by the infrared light emitting device at the time of next infrared light emission based on the comparison between the strength of the reflected infrared signal received by the infrared light receiving device and a preset value set in the position sensitive detector. Thus, by switching between different emitting strength modes, the infrared light emitting device is made to use an emitting mode with a weak strength in the case that no one is using the position sensitive detector, thereby effectively decreasing the power consumption of the position sensitive detector in its operation.

摘要： A light refracting element formed in parallel plate shape is attached to a support shaft of a mirror holder, a semiconductor laser and a PSD are disposed at positions between which the light refracting element is sandwiched. The light refracting element is rotated by rotation of the mirror holder, and whereby a laser beam irradiation position is changed on a light acceptance surface of PSD. The laser beam irradiation position on a light acceptance surface corresponds to the mirror rotation position, so that the mirror rotation position and a laser beam scanning position in a target area can be detected based on an output from the PSD.

摘要： An apparatus detects an object using an optoelectronic apparatus. Light beams generated by a light source are scattered back and/or reflected by an object and are detected by a receiver arrangement in accordance with the triangulation principle. An object detection signal is output by an evaluation unit and the light beams in the receiver arrangement act via an optical receiver system and a microlens array on a pixel array comprising photodetectors. A macropixel has a plurality of subpixels associated with each microlens. The evaluation unit comprises a unit for determining the received signal distribution over the subpixels. Methods for operating the apparatus are also provided.
