摘要：
A physiological information detection system may include an add-on device in electronic communication with a computing device. The add-on device includes a body and a first light filter retained in the body. The first light filter filters light emitted by the light source of the computing device. A lens is also retained in the body proximate the first light filter. The lens directs light exiting the first light filter out a surface of the first lens. The body retains a second lens that receives into a surface of the second lens light exiting the first lens. The surface of the first lens and the surface of the second lens are substantially coplanar. A second light filter is also retained in the body proximate the second lens. The sensor detects the light exiting the second light filter.
