  • Patent number: 10384152
    Abstract: Embodiments of the present invention include a backscatter reductant anamorphic beam sampler. The beam sampler can be implemented to measure a power of a reference beam generated by an electromagnetic radiation source in proportion to a power of a working beam. The beam sampler can provide astigmatic correction to a divergence of the working beam along one axis orthogonal to a direction of propagation. The beam sampler can further be implemented to prevent backscatter from impinging upon a photodetector of the beam sampler resulting in a reduction of error and instability in measurements taken by the beam sampler.

  • Patent number: 10381504
    Abstract: An optical detection sensor functions as a proximity detection sensor that includes an optical system and a selectively transmissive structure. Electromagnetic radiation such as laser light can be emitted through a transmissive portion of the selectively transmissive structure. A reflected beam can be detected to determine the presence of an object. The sensor is formed by encapsulating the transmissive structure in a first encapsulant body and encapsulating the optical system in a second encapsulant body. The first and second encapsulant bodies are then joined together. In a wafer scale assembling the structure resulting from the joined encapsulant bodies is diced to form optical detection sensors.

  • Patent number: 10325947
    Abstract: An image sensor operable in global shutter mode may include an array of image pixels. Each image pixel may include a photodiode for detecting incoming light and a separate storage diode for temporarily storing charge. To maximize the efficiency of the image pixel array, image pixels may include light guide structures and light shield structures. The light guide structures may be used to funnel light away from the storage node and into the photodiode, while the light shield structures may be formed over storage nodes to block light from entering the storage nodes. The light guide structures may fill cone-shaped cavities in a dielectric layer, or the light guide structures may form sidewalls having a ring-shaped horizontal cross section. Metal interconnect structures in the dielectric layer may be arranged in concentric annular structures to form a near-field diffractive element that funnels light towards the appropriate photodiode.

  • Patent number: 10317278
    Abstract: Differing from conventional ambient light sensors at least having drawbacks of huge circuit area and high manufacturing cost, the present invention discloses an ambient light sensor showing advantages of small circuit area and low manufacturing cost. This ambient light sensor has functionality of photodiode leakage current compensation, and comprises: a temperature sensing unit, a microprocessor unit, a conversion unit, and a lookup table unit. The microprocessor unit is configured to find out a reference parameter for a first dark current from the lookup table unit according to a measured data of ambient temperature. Subsequently, the conversion unit is controlled to apply a current amplifying process to a second dark current. Therefore, after subtracting an output current of the first photodiode from the second dark current been treated with the current amplifying process, the output current been treated with a leakage current compensating process is produced and outputted.
