There is provided a temperature measurement system including an image sensor, a thermal sensor and a processor. The image sensor captures an image frame. The thermal sensor captures a thermal image. The processor calibrates measured temperatures of the thermal sensor and calibrates offset pixels between the image frame and the thermal image corresponding to different operating distances.

An optical sensor assembly is provided. The optical sensor assembly includes a circuit board, an optical sensor positioned on the circuit board, and a front cover attached to the circuit board and covering the optical sensor. The front cover includes an optical element configured to guide or condense an incident light of a predetermined wavelength onto the optical sensor. The front cover is made of polypropylene or polyethylene. The predetermined wavelength is in a range from 8 micrometers to 12 micrometers.
