We present the design of an imaging fiber bundle lens that consists of an objective lens and a coupling lens. The objective lens has an operating wavelength of 0.4 to 0.7 µm, a field of view of 60 deg, and an outer diameter of 9.5 mm. The coupling lens has an operating wavelength of 0.4 to 0.7 µm, a field of view of 6 mm, and an outer diameter of 7.7 mm. The imaging quality of an imaging fiber bundle lens has been experimentally demonstrated.
Since the first laser-needles acupuncture apparatus was introduced in therapy, this kind of apparatus has been well used in
laser biomedicine as its non-invasive, pain- free, non-bacterium, and safetool. The laser acupuncture apparatus in this
paper is based on single-chip microcomputer and associated by semiconductor laser technology. The function like
traditional moxibustion including reinforcing and reducing is implemented by applying chaos method to control the duty
cycle of moxibustion signal, and the traditional lifting and thrusting of acupuncture is implemented by changing power
output of the diode laser. The radiator element of diode laser is made and the drive circuit is designed. And chaos
mathematic model is used to produce deterministic class stochastic signal to avoid the body adaptability. This function
covers the shortages of continuous irradiation or that of simple disciplinary stimulate signal, which is controlled by some
simple electronic circuit and become easily adjusted by human body. The realization of reinforcing and reducing of
moxibustion is technological innovation in traditional acupuncture coming true in engineering.
