Abstract
Biomedical applications of new technologies in opto-electronics are described.
The first part of this paper describes principle and medical applications of SELFOC. SELFOC is a new type of fibre-optic light guide, where distribution of the refractive index is parabolic in radial direction. SELFOC can transmit not only a single laser beam but also a bundle of laser beams and an image. As a typical example of the medical applications of SELFOC, SELFOC arthroscope is described.
The latter part of this paper describes principle and biomedical applications of holo-graphy. The principle of holography is explained in an elementary way, where wave-front reconstruction property of a hologram is emphasized. Biomedical applications of holographic interferometry and holographic microscopy are described. Holographic storage of medical information is discussed. A graphic input device utilizing holography, Holotablet, is also described.
