Abstract
Official abstract text for this publication.
The internal propagation of radiation between a radiation source and radiation detector mounted within a sensor package is prevented by the use of an optical isolator. The optical isolator is formed by the combination of a baffle mounted between the source and detector and a groove formed in an upper surface of the sensor package between the source and detector. A bottom of the groove is positioned adjacent to an upper edge of the baffle.
First claim
Opening claim text (preview).
What is claimed is: 1. A proximity sensor comprising: a sensor package comprising a lens module; a radiation source and a radiation detector housed within the sensor package, the lens module of the sensor package being positioned over the source and the detector; and an optical isolator adapted to substantially prevent internal propagation of radiation between the source and the detector within the sensor package, the optical isolator comprising: a baffle positioned within the…
