    摘要： An optical sensor device comprises a light source, a light detector, and an opaque light barrier including a first portion to block light from being transmitted directly from the source to the detector. A second portion of the light barrier extends from the first portion in a direction towards the light source, such that a portion of the second portion covers at least a portion of light emitting element(s) of the source, to reduce an amount of specular reflections, if a light transmissive cover plate were placed over the sensor. Additionally, a third portion of the barrier can extend from the first portion, in a direction towards to the detector, such that a portion of the third portion covers at least a portion of light detecting element(s) of the detector, to reduce an amount of specular reflections that would be detected by the detecting element(s) of the detector, if a light transmissive cover plate were placed over the sensor. Additionally, an off-centered lens can cover a portion of the light source.

    摘要： An optical sensor device, according to an embodiment of the present invention, includes a light source and a light detector. The light source includes one or more light emitting elements, and the light detector includes one or more light detecting elements. A first opaque light barrier portion, between the light source and the light detector, is configured to block light from being transmitted directly from the light source to the light detector. A second opaque light barrier portion, extending from the first opaque light barrier portion in a direction towards the light source, is configured to reduce an amount of specular reflections that would occur if a light transmissive cover plate were placed over the optical sensor device. A third opaque light barrier portion, extending from the first light barrier portion in a direction towards to the light detector, is configured to reduce an amount of specular reflections that would be detected by the light detector, if a light transmissive cover plate were placed over the optical sensor device.

    摘要： Provided herein are optical sensor devices, methods for making the same, and systems including the same. An optical sensor device, according to an embodiment, includes a light detector die and a light source die attached to the same or different die attachment substrates so that there is a space between the light source die and the light detector die. A light transmissive material covers the light detector die, the light source die and at least a portion of the space between the light detector die and the light source die. A groove is formed (e.g., saw, blade or laser cut, or cast) in the light transmissive material between the light detector die and the light source die, and an opaque material is put within the groove to provide a light barrier between the light detector die and the light source die.
