摘要： An optical proximity sensor is provided that comprises an infrared light emitter operably connected to and driven by a light emitter driving circuit and a light detector operably connected to and driven by a detector sensing circuit. A metal housing or shield formed of metal and comprising first and second apertures surrounds the light emitter and the light detector such that at least a first portion of light emitted by the light detector passes through the first aperture, and at least a second portion of the first portion of light reflected from an object of interest in proximity to the sensor passes through the second aperture for detection by the light detector. The metal housing or shield further comprises first and second modules within which the light detector and light detector are disposed, respectively. The first and second modules comprise adjoining optically opaque metal inner sidewalls that provide optical isolation between the first and second modules, where the first and second inner sidewalls are separated from one another by at least one metal tab foldably disposed therebetween. The at least one metal tab is configured to transfer a vertical force applied to one end of one module to an opposite end of the other module.

摘要： Various embodiments of a miniaturized optical proximity sensor are disclosed. In one embodiment, an ambient light sensor and a light detector are mounted on first and second spacers, which in turn are mounted to a top surface of an integrated circuit die-attached to a substrate. An optically-transmissive infrared pass compound is molded over the ambient light sensor, the light detector, the integrated circuit, a light emitter and peripheral portions of the substrate. Next, an optically non-transmissive infrared cut compound is molded over the optically-transmissive infrared pass compound to provide a miniaturized optical proximity sensor having no metal shield but exhibiting very low crosstalk characteristics.

摘要： Reflection of light from a surface is sensed by emitting light from a light emitting diode and focusing the light using an aspherical emitter lens to illuminate a reflecting surface. Light reflected by the reflecting surface is focused onto a photodetector using an aspherical collector lens. The light emitting diode is displaced from the optical axis of the aspherical emitter lens and the photodetector is displaced from the optical axis of the aspherical collector lens.

摘要： An optical proximity sensor is provided that comprises an infrared light emitter an infrared light detector, a first molded optically transmissive infrared light pass component disposed over and covering the light emitter and a second molded optically transmissive infrared light pass component disposed over and covering the light detector. Located in-between the light emitter and the first molded optically transmissive infrared light pass component, and the light detector and the second molded optically transmissive infrared light pass component is a gap. Layers of infrared opaque, attenuating or blocking material are disposed on at least some of the external surfaces forming the gap to substantially attenuate or block the transmission of undesired direct, scattered or reflected light between the light emitter and the light detector, and thereby minimize optical crosstalk and interference between the light emitter and the light detector.

摘要： A system for identifying a characteristic of a printing media includes a light source module that has a light emitting diode (LED) and an aspheric lens and a light detection module that has a photodetector and an aspheric lens. The light source module and light detection module are oriented with respect to a printing media such that the focusing points of the respective aspheric lenses are located at a common position on the printing media. The system differentiates between printing media types by applying light to the surface of the printing media and measuring the light that is reflected from the surface.
