Title: Miniature electric furnace for processing optical fiber
Inventor: HIRAYAMA MAMORU
IPC: G02B6/28
Filed: 1989-12-18
Abstract: PURPOSE:To improve the reproducibility of temperature distribution and that of the processed form of an optical fiber by using a furnace core tube and closely attaching a metal foil to the surface of the core tube or forming a metal thin film on the surface and heating the metal foil, etc., by passing electric current to heat the furnace core tube. CONSTITUTION:A metal foil 3 (e.g. platinum foil) is used as a heating material and closely attached to the surface of a furnace core tube 1 (e.g. alumina insulation tube) having both opened ends or a metal thin film 7 (e.g. platinum film) is formed on the surface to obtain a miniature electric furnace for processing an optical fiber. Electric current is passed through the metal foil 3 or the metal thin film 7 to heat the furnace core tube 1 by the generated heat. An optical fiber 4 is introduced into the furnace core tube 1 to perform the thermal processing such as drawing or welding of the optical fiber 4. The use of the furnace core tube 1 is effective in reducing the size of the apparatus and preventing the influence of wind pressure to cause the bending of the optical fiber.

Abstract: PURPOSE:To measure the surface roughness of an object with high accuracy extending over a wide range by projecting at least two luminous fluxes in which wavelength of the luminous fluxes or incident angles of the luminous fluxes to the surface to be measured are different from each other. CONSTITUTION:By using two light projecting parts 2A, 2B being independent from each other, two luminous fluxes 3A, 3B are projected to different positions of the surface to be measured 1. The luminous fluxes 3A, 3B are reflected by the surface to be measured 1, and generated reflected light intensity distributions 4A, 4B, respectively. Also, two photodetectors 5A, 5B being photodetecting means and independent from each other detect the reflected light intensity distributions 4A, 4B by scanning on a circular arc centering around each reflecting point of the surface of be measured 1. Moreover, as for a sample base 6, by moving in the vertical direction to two luminous fluxes 3A, 3B, the respective luminous fluxes 3A, 3B can irradiate successively the same point on the surface to be measured 1. In this state, by deriving the regular reflection intensity corresponding to each incident luminous flux 3A, 3B, based on an output signal of the photodetecting means by a signal processor, the surface roughness of the surface of be measured can be calculated.
