NON-REFLECTIVE OPTICAL CONNECTIONS IN LASER-BASED PHOTOPLETHYSMOGRAPHY |
摘要 |
An embodiment of a light delivery portion of a photoplethysmographic device having a series of two or more optical elements. The series of two or more optical elements (20, 40, 50) are arranged to conduct light (10) from a laser and at least two consecutive elements of the series of two or more optical elements are coupled together by a non-reflective coupling (30a, 30b). This minimizes the extent to which back reflected light can re-enter the laser and adversely alter the optical output properties of the laser and additionally minimizes the light loss associated with back reflection thus helping to maximize the optical throughput. Other embodiments are described and shown. |
