Abstract
A photoplethysmographic device includes a photoplethysmographic monitor, two or more emitters coupled to and controlled by the monitor, the emitters including at least one laser and at least one of the at least one lasers is a tapped laser configured to emit light through a primary optical path from the emitter to a sensor, and a photodetector coupled to the monitor and positioned to receive light tapped from the tapped laser prior to the point where the light exits the sensor, the photodetector generating an electrical signal indicative of the intensity of the amplitude of the light tapped from the tapped laser. The monitor processing the electrical signal to determine the condition of the tapped laser, whereby the monitor determines if the tapped laser is damaged and/or if one or more operating conditions of the tapped laser need to be altered.
