    • Disclosed is a method of detecting bubbles issuing from a hermetic container. A hermetic container, i.e., an object to be measured, is immersed in a liquid, and pressurized air is applied to this hermetic container to produce bubbles from a leaking portion. The bubbles are allowed to pass between a pair of optical fibers provided with a gap therebetween. At that time, a light beam emitted from one optical fiber and received by the other optical fiber is radiated across the intended pathway of the bubbles. When the light beam passes through the bubbles, the beam is diffused by the difference in density between the liquid and the bubbles, a reduced part of it is received by the other optical fiber, and the amount of light thus received is converted to an electrical signal. In addition, an apparatus for detecting bubbles for implementing this method is also disclosed.
    • 公开了一种检测从密封容器发出的气泡的方法。 将密封容器即待测物体浸入液体中,将加压空气施加到该密封容器上,以从泄漏部分产生气泡。 允许气泡在设置有间隙的一对光纤之间通过。 此时,从一根光纤发射并被另一根光纤接收的光束穿过气泡的预定路径被辐射。 当光束穿过气泡时,光束被液体和气泡之间的密度差扩散,其中一部分被另一根光纤接收,并且这样接收的光量被转换为电 信号。 此外,还公开了一种用于实现该方法的用于检测气泡的装置。
