Holographic pulse diagnosis instrument based on laser scanning three-dimensional dynamic profile measurement technology

Abstract

The invention discloses a holographic pulse diagnosis instrument based on a laser scanning three-dimensional dynamic profile measurement technology and mainly relates to the field of traditional Chinese medicine pulse detection devices. The instrument comprises a detection workbench, a computer, a supporting rack, an air bag device assembly, an air inflation device assembly for inflating the air bag device assembly and a position adjustment device assembly. The holographic pulse diagnosis instrument further comprises a line beam laser, a surface scanning galvanometer, a high-speed digital video camera and a convex lens which are fixed on the supporting rack, the high-speed digital video camera is connected with the computer through a data cable, and the surface scanning galvanometer is connected with the computer through a signal line; the position of the convex lens corresponds to the position of the high-speed digital video camera and the position of the air bag device assembly, anda reflection mirror on the surface scanning galvanometer can quickly rotate back and forth within a ruled angle range in the axial direction. The holographic pulse diagnosis instrument has the advantages that by adopting the laser scanning three-dimensional dynamic profile measurement technology, the requirements for optical paths and optical path devices are high, the instrument is easier and more convenient to use, low in cost and higher in practicability and accuracy.

Problems solved by technology

After further exploration and research by the applicant, it is found that the optical interference microscope structure assembly (Michelson interference structure, Milo interference structure or Linick interference structure) has the following disadvantages: the requirements for the setting of the optical path are relatively high, and the three types of interference The structure of the optical path used in the structure is complex, involving beam expanders, beam splitters, microscope imaging objectives, beam splitting prisms, camera imaging lenses, mirrors, total reflection mirrors, beam splitters, microscope objectives, reference objective lenses and other optical structures, and The requirements for the position of the optical path between the various optical structures are relatively high, and at the same time, they are more easily affected by factors such as environmental vibrations, and the production cost is high, so it is inconvenient to use
