Real-time optical power measurement device including a pair of thermocouples and method for operating thereof

摘要

The present invention relates to an apparatus for measuring real-time light output including a pair of thermocouples and a thin metal plate and a method of operating the same. The optical power measuring apparatus according to an embodiment of the present invention includes: a first sensor including a first metal wire, a first thermocouple including a second metal wire, and a first metal thin plate; A second sensor including a third metal wire, a second thermocouple including a fourth metal wire, and a second metal thin plate; And a controller configured to calculate a light output and a surface temperature of a light source that irradiates light to the first sensor and the second sensor by calculating a temperature difference between temperatures measured by the first sensor and the second sensor.
