Abstract
An integrated circuit device includes an insulating body provided with a number of electrically conductive leads and having a surface provided with a red LED aperture, an IR LED aperture and a photodetector aperture. The insulating body also includes an optical isolator optically separating the photodetector aperture from the red LED aperture and the IR LED aperture. A red LED is aligned with the red LED aperture, an IR LED is aligned with the IR LED aperture, and a photodetector is aligned with the photodetector aperture.
Claims7
An integrated circuit device comprising:
- an insulating body provided with a number of electrically conductive leads and having a surface provided with a red LED aperture, an IR LED aperture and a photodetector aperture, the insulating body including an optical isolator separating the photodetector aperture from the red LED aperture and the IR LED aperture;
- a red LED disposed within the insulating body and aligned with the red LED aperture;
- an IR LED disposed within the insulating body and aligned with the IR LED aperture;
- a photodetector disposed within the insulating body and aligned with the photodetector aperture;
- and
- an optical filter array disposed over the photodetector and having a grid-like pattern of red (R) and IR filter segments arranged in a plurality of rows and a plurality of columns, wherein the R and IR filter segments alternate in both the rows and columns.
