An Initial Study on Multi-Point Laser Acupuncture Based on 2-D Galvo Mirror.

Currently, the majority of commercially available laser acupuncture instruments are still hand-held and only support single-point stimulation. Simultaneous multi-point stimulation improves the therapeutic efficacy of laser acupuncture by stimulating multiple acupoints at the same time. A "2-dimensional (2-D) galvo mirror" was utilized as a positioning laser acupuncture device for multi-acupoints stimulation. Due to its ability to perform 2-D fast scanning, a single laser beam was reflected by the mirror and stimulated multiple acupuncture points simultaneously. This introduction to the new system, presents its architecture, and shows some initial results. This initial stage of development was focused on the acupoints of the human forearm. This proposed system is the first low-cost, noncontact laser acupuncture system that enables continuous multi-acupoint stimulation with a single laser beam. Notably, it is technically feasible to develop this technique into a whole-body laser acupuncture stimulation system.
