アイバー・ヘツドと箱の天井から吊された振り子
の下端に取り付けられた光反射物とを、光反射物
がフアイバー・ヘツドの投光面と受光面との正面
に位置するように配置し、箱が傾くか横転するか
或は振動を受けるかするとフアイバー・ヘツドの
投光面と受光面との正面から光反射物がずれて、
フアイバー・ヘツドの投光面から投光されて受光
面へ戻る光量を変化させてそれを電気信号として
取り出せるようにした光フアイバー・センサー。 Inside the box, connect the fiber head of the reflective optical fiber sensor and a light-reflecting object attached to the bottom end of a pendulum suspended from the ceiling of the box. If the box is tilted, rolled over, or subjected to vibration, the light reflecting object will shift from the front of the fiber head's light emitting surface and light receiving surface.
An optical fiber sensor that changes the amount of light emitted from the light-emitting surface of the fiber head and returns to the light-receiving surface so that it can be extracted as an electrical signal.
