The non-contact thickness gauge includes an X-ray thickness gauge, an ultrasonic thickness gauge, an infrared thickness gauge, a laser thickness gauge, and the like. For example, a laser thickness gauge in the prior art is implemented by a laser double reflection measurement method, and the measurement principle is that a laser displacement sensor is used for measuring the vertical displacement of a measured object to calculate the thickness of the measured object, when the thickness of the measured object changes, laser emitted by a laser generator irradiates the measured object, the laser irradiates the position on a laser receiver after being reflected to generate displacement change, the thickness change of the measured object can be known through geometric calculation, and a thickness signal is output in a digital or curve manner. However, such a laser thickness gauge generally includes two laser displacement sensors which are vertically opposed to each other, and the two upper and lower sensors measure the position of the upper surface and the position of the lower surface of the object to be measured, respectively, and calculate the thickness of the object to be measured. Because need two upper and lower laser displacement sensor, just need fix laser displacement sensor respectively in the upper and lower both sides of testee, occupy extra space, and need calibrate two upper and lower sensors respectively, increased the error that probably brings.
