    摘要： In the present invention, a deformation process is applied to a part of an image fiber, and when implementing improvement of the quality of the transmitted image, the improvement of the image quality in the center region and peripheral region of the image fiber in the radial direction is carried out to an equal degree, and a uniform improvement of the entire screen can be carried out. A processed part is formed having a deformation of all cores that is substantially identical by deforming in the radial direction or by deforming and twisting a part of an image fiber having a plurality of cores that function as pixels in the radial direction thereof. The image fiber can be manufactured by a processing in which by a part of the image fiber having a plurality of cores that function as pixels is heated, and deformed in the radial direction thereof or simultaneously deformed and twisted in the radial direction thereof this heated part.

    摘要： An image fiber includes an image fiber body having a twisted portion which is formed by heating, softening, and twisting a portion of the image fiber body. The rate of twist in the twisted portion is made to be constant. Moreover, the rate of twist may preferably be set in a range from 1°/mm to 4000°/mm. In addition, the rate of twist at the beginning portion of the twisted portion and the rate of twist at the end portion of the twisted portion may preferably be set in a range from 3°/mm to 400°/mm. The twisted portion may be provided with a protective element.

    摘要： A welding observation apparatus is provided to use partial darkening by a telecentric optical system and a photochromic filter (PCF) as an optical system for filtering light emission from arc discharge in order to verify the welding condition under the welding arc discharge, without forming an image on the PCF, so that light reducing performance can be secured even if a focus shifts from on the PCF, with satisfactory monitoring of welding condition.The welding observation apparatus comprises: an arc welding unit 8; an objective optical system (1, 2) for concentrating light from the arc welding unit 8; a telecentric optical system 3 for guiding the light concentrated by the objective optical system (1, 2); a PCF 4 for illuminating with the light guided by the telecentric optical system 3; and a solid state imaging device 9 for receiving the light passing through the PCF 4, wherein the light from the arc welding unit 8 is partial-darkened by the PCF 4.
