摘要：
An optical measurement device and a method for optical measurement are provided. The device comprises an illumination assembly configured to output light to a surface portion of a user for measurement a detection assembly configured to detect the output light reflected from said surface portion of the user as a signal an amplifier module coupled to the detection assembly configured to apply a gain to an AC component of the signal a microcontroller coupled to the detection assembly configured to assess a DC voltage level of the signal wherein the microcontroller is configured to control the light output at the illumination assembly based on said assessing the DC voltage level and further wherein the microcontroller is configured to select a gain value for said applying the gain based on said assessing the DC voltage level. Specific embodiments of the device relate to a photoplethysmograph or pulse oximeter.
