Thermopile Laser Sensor with Response Time Acceleration

Abstract

The present application discloses an improved thermopile laser sensor apparatus. In one embodiment, the apparatus includes a sensor body, a substrate in thermal communication with the sensor body, and an absorber configured to absorb a portion of a beam of laser energy. A first thermal sensor in thermal communication with the substrate and a second sensor in thermal communication with the sensor body are separated by a thermal barrier configured to reduce a rate of transfer of thermal energy between the first thermal sensor and the second thermal sensor. The first thermal sensor is configured to transmit a first signal to a processor, and the second thermal sensor is configured to transmit a second signal to the processor device, wherein the processor is configured to process the first signal and the second signal and calculate a compensated laser power reading to be shown on a display.
