Multi-focus physiologic sensing device for condensing light
First Claim
1. A multi-focus physiologic sensing device for condensing light comprising:
- at least two lighting elements each generating a light source;
at least one multi-focus condenser having at least one first ellipse reflection member and at least one second ellipse reflection member, and said second ellipse reflection member is arranged at an end of said first ellipse reflection member, and said first ellipse reflection member has a first transparent plane and a first focus point thereon, and said second ellipse reflection member has a second transparent plane and at least two second focus points thereon, and a boundary between said first ellipse reflection member and said second ellipse reflection member has a first confocal point, and said two lighting elements are respectively arranged on said two second focus points to generate said two light sources, and said two light sources focus light on said first confocal point through said second ellipse reflection member whereby said light is incident on a detected object to form a detected light source, and then said detected object reflects said detected light source back to said first confocal point whereby said detected light source is emitted exit from said first focus point after reflection; and
at least one sensor arranged on said first focus point of said multi-focus condenser and receiving said detected light source to detect a physiologic state.

Abstract
A multi-focus physiologic sensing device for condensing light is disclosed, comprises a multi-focus condenser has one first ellipse reflection member, and one second ellipse reflection member is arranged at an end of the first ellipse reflection member. The first ellipse reflection member has a first focus point thereon. The second ellipse reflection member has two second focus points thereon. A boundary between the first ellipse reflection member and the second ellipse reflection member has a first confocal point. Two lighting elements are respectively arranged on the two second focus points to generate light sources, that focus light on the first confocal point through the second ellipse reflection member, and then the detected object reflects the detected light source back to the first confocal point. Then, the detected light source is passes through the sensor from the first focus.
