  • Optical encoder
    Patent number: 11092465
    Abstract: An optical encoder includes first, second, and third light receiving elements (A, B, C) that are sequentially disposed and adjacent to each other; and a detection signal generation unit (50) that outputs a detection trigger (Ts) when an output level of the second light receiving element (B) that receives incident light after the first light receiving element (A) is higher than an output level of the first light receiving element A, and outputs a non-detection trigger (Te) when an output level of the third light receiving element (C) that receives incident light after the second light receiving element (B) is higher than the output level of the second light receiving element (B).

  • OPTICAL REFLECTION SENSOR AND ELECTRONIC DEVICE
    Publication number: 20170199272
    Abstract: An optical reflection sensor includes a light emitting element that irradiates a distance measuring target with light, a light receiving optical system that condenses reflected light from the distance measuring target, a light receiving element that receives light condensed by the light receiving optical system and outputs a photoelectric current signal corresponding to a light receiving position, and a signal processing circuit that obtains light receiving position information on the light receiving element and time-of-flight information of the light, which is a duration from when the light is emitted by the light emitting element to when the light is reflected by the distance measuring target and received by the light receiving element, on the basis of the photoelectric current signal output from the light receiving element.
