る樹脂が極低温で可撓性を有しないことのためである。If the fiberscope has flexibility at a cryogenic temperature, it is very convenient because a signal can be extracted from the back side of the object in the cryostat and the back side of the object can be freely observed by remote control. However, existing fiberscopes are not flexible at cryogenic temperatures. that is
(1) The sheath of the fiberscope does not have flexibility at cryogenic temperature, and (2) the resin filled between the fibers is flexible at cryogenic temperature to prevent damage caused by rubbing scratches between the fibers. It is for not having.

A super insulation layer provided between the outer bellows and the inner bellows, and a plurality of spacer members arranged in the super insulation layer and made of a heat insulating material for preventing contact between the inner and outer bellows. And a heating heater wound around the tip of the fiber bundle main body to provide a cryogenic fiberscope. If a manipulator that moves and bends the fiberscope remotely is required, mount it inside or outside the fiberscope.

ものになる。When the fiberscope is configured as described above, the fiber bundle and the like are maintained at a temperature at which the fiberscope shows flexibility at about room temperature. Further, since the bellows constituting the sheath has flexibility at extremely low temperatures, the entire fiberscope has flexibility for extremely low temperatures.

きた。FIG. 1 shows an example of a fiberscope for image transmission that can be used at extremely low temperatures. The sheath is composed of bellows 1 and 2, and the outer layer 3 composed of bellows 1 and 2 is a super insulation layer. Spacers 4 made of a heat insulating material are arranged at appropriate intervals in the super heat insulating layer 3 in order to prevent contact between the bellows 1 and 2. A fiber bundle 5 is inserted inside the bellows 2, and a heating heater (in order to avoid loss of flexibility at the tip of the fiber bundle due to cooling through the objective lens system 6 near the tip thereof) ( A cloth heater 7 is wrapped around. Although illustration of the power supply of the heater and the connection from the power supply to the heater is omitted, the former is arranged outside the fiberscope and the latter is arranged inside the bellows 2. An eyepiece lens system 8 is attached to the other end of the fiberscope. With this fiberscope, good results could be obtained by observing the crack growth of the test piece for fatigue test at cryogenic temperature.
