Embodiment Construction

[0033] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The same elements will be denoted by the same reference numerals in explaining the drawings and will not be described repeatedly.

[0034] figure 1 is a block diagram showing an embodiment of the optical fiber observation apparatus according to the present invention. This figure is a view taken along the direction of the optical axis of a plurality of optical fibers 2 being observed. The optical fiber observation device 1 has a pair of light sources 3, 4, and the light sources are positioned obliquely above the placement surface 14 on both sides of a plurality (for example, 12 pairs) of optical fibers 2, and the optical fibers are arranged in parallel on the placement surface 14 and are in a flat shape, The observation device also has a pair of microscopic cameras (observation units) 5 , 6 which are located obliquely below the placement surface 14 . Ea...

Abstract

Each imaging optical system has a rear lens system whose front focus is at the rear focus position of the front lens system. Each optical axis is disposed in a direction perpendicular to the optical axis of the optical fiber and different from the perpendicular direction of the surface on which the optical fiber is placed. Each image pickup surface of the CCD is tilted relative to the optical axis of the imaging optical system so that the longer the object distance of each fiber in the optical fiber is, the shorter its image distance is, and each image pickup surface is set parallel to the optical axis of the fiber. in the direction.

Description

technical field [0001] The present invention relates to an observation device for observing the position of an optical fiber and a fusion splicer using the optical fiber observation device. technical background [0002] A conventional optical fiber observation device is disclosed in Japanese Patent Application Publication No. 1-107218. The conventional optical fiber observation apparatus described in this application is an apparatus that emits light beams from obliquely above to a plurality of optical fibers fixed in a row on a bracket and picks up the phase at the optical fiber joint portion irradiated by the light through a TV camera located obliquely below. An image of the proximal face. [0003] Figure 9 It is a view showing the optical system in the existing fiber optic observation equipment. Such as Figure 9 As shown, the image pickup surface 100 of the TV camera is set at a position perpendicular to the optical axis 102 of the optical lens ...
