Work Up

An inexpensive fiber-based noncontact distance sensor specific for monitoring short-range displacements in micromachining applications is presented. To keep the overall costs low, the sensor uses plastic optical fibers and an intensiometric approach based on the received light intensity after the reflection from the target whose displacement has to be measured. A suitable target reflectivity compensation technique is implemented to mitigate the effects due to target surface nonuniformity or ageing. The performances of the sensor are first evaluated for different fiber configurations and target reflectivity profiles and positions using a numerical method based on Monte Carlo simulations. Then, experimental validations on a configuration designed to work up to 1.5 mm have been conducted. The results have confirmed the validity of the proposed sensor architecture, which demonstrated excellent compensation capabilities, with errors below 0.04 mm in the (0-1) mm range regardless the color and misalignment of the target.

Colon hydropathy implies that the filtrated water pumped into the rectum keeps regular colon squirm, and sweeps away poisonous excrements. The PC-based ryodoraku technique has played increasingly important role in the field of traditional Chinese medicine because of its advantages of better preventive diagnosis, less side effects and inexpensive medicare. Since the 1950’s, Dr. Nakatani Yoshio has developed the ryodoraku methodology to measure skin resistance for the purpose of preventive diagnosis based on Chinese acupuncture and the qi-field theory. From the viewpoint of the preventive medicine, rehabilitated smooth muscles and well-balanced probiotics would improve self-repair functions and reduce the carcinogen of the colon. However, long-lasting hydropathical process for existed products on the market may result in unpredictable side effects from the viewpoint of drug dynamics. On the other hand, repeated use of colonoscopes could not only be expensive but contaminative in considering of colon viruses. This paper is focused on the clinical research of the drug dynamics and the development of a PC-based technique in the colon hydropathy. A clinical platform with disposable optical fibers is schemed to assure the biomorphic balance of colon. Finally, clinical experiments are carefully schemed to justify the advantages of the proposed algorithm in Tse-En Clinic of Traditional Chinese Medicine.

Good Agreement

So far, the commonly used optical parametric oscillators (OPOs) relying on [Formula: see text] nonlinearity in the bulk materials have been extensively investigated both theoretically and experimentally, but not enough attention has been paid to OPOs based on [Formula: see text] nonlinearity in optical fibers. In this paper, a singly resonant fiber optical parametric oscillator (FOPO) is theoretically studied and its main aspects are simulated. Also, impacts of various parameters including the pump and signal wavelengths, the fiber length and dispersion as well as the input coupler on the conversion efficiency of the FOPO are investigated. Finally, the simulation results are compared with the available experimental data and a very good agreement is obtained.
