[0018] The specific embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.
[0019] Such as figure 1 As shown, the central wavelength of the broadband light source is 1550nm, and the spectral line width is 1525-1525nm. The transmission fiber 6 is a single-mode fiber; the microprocessor 9 outputs a pressure control signal to the pneumatic pressure control device 5 to adjust the pressure applied by the test head 4 to the pulse position of the human body, simulating the three-finger pulse of Chinese medicine.
[0020] Such as figure 2 with image 3 In the structure shown, the spring 18 is a micro spring. The elastic force of the micro spring is much smaller than the thrust of the connecting rod on the slider. The main function of the micro spring is to ensure that the slider 20 moves flexibly with the pulse and does not lag behind the pulse. And to ensure that the slider returns to the initial position in time to ...
