    • A connector (50) receives and grips an optical fibre (F) in registry with an optical element (53). Pivoting portions (22, 32) are held in default inoperative position by the spring action of moulded hinges (21, 31), at which position two shutter portions (24, 34) meet, so forming a shutter preventing the ingress of dirt to the optical element. This is the default position when the connector is not being used. As the optical fibre (F) is pushed a small distance into the connector, the pivoting portions (22, 32) are caused to pivot a small amount about the hinges (21, 22), bringing teeth (23, 33) into contact with the outside jacket of the fibre (F).The bodies (20, 30) of the inserts are forced radially away from the central axis of the connector, so providing a leaf spring force which keeps the teeth (23, 33) engaged with the jacket of the fibre (F). The shutter portions (24, 34) move out of the way of the fibre (F) and the spring action applies a force to draw the fibre (F) further into the body of the connector (50).When the fibre (F) has been pushed home the bodies of the inserts (20, 30) have been able to relax partially in the radial direction towards their normal position, but continue to exert a spring force on the teeth (23, 33). This force acts both to keep the teeth engaged in the jacket of the fibre, and to push the fibre F firmly against the optical element (53), so that the fibre F is held in the connector (50) in the engaged position.
    • 连接器(50)接收和夹持与光学元件(53)对准的光纤(F)。 枢转部分(22,32)通过模制铰链(21,31)的弹簧作用保持在默认的不起作用的位置,在两个闸板部分(24,34)相交的位置处,从而形成挡板,防止污物进入 光学元件。 这是连接器未使用时的默认位置。 当光纤(F)被推入连接器的距离较小时,枢转部分(22,32)绕铰链(21,22)枢转少量,使得齿(23,33)与 插入件的主体(20,30)被迫径向远离连接器的中心轴线,从而提供一个弹簧力,该弹簧力使齿(23,33)与 纤维夹克(F)。 快门部分(24,34)移动离开光纤(F)的路径,并且弹簧动作施加力以进一步将光纤(F)拉入连接器(50)的主体中。当光纤(F) 已被推回家中,插入件(20,30)的主体已经能够沿径向部分地朝向其正常位置松弛,而是继续在齿(23,33)上施加弹簧力。 该力既作用于保持齿接合在纤维的护套中,并且将纤维F牢固地推靠在光学元件(53)上,使纤维F保持在接合位置的连接器(50)中。

    • A laser sensor is used as a velocimeter using principles of self-mixing. A laser device having an optical cavity with an optical output face and a beam splitter integrated into the laser device provides at least two output beams from the optical output facet. A first one of the output beams is used as a probe beam directed to a target surface external to the sensor and a second one of the output beams is used as a monitor beam directed to an optical detector which measures the laser output power. From the measured output power, motion of the target surface relative to the sensor is determined as a function of self-mixing of a portion of the probe beam returned to the optical cavity by reflection from the target surface.
    • 使用自混合原理将激光传感器用作测速仪。 具有光学腔的光学输出面的激光装置和集成到激光装置中的分束器提供至少两个来自光学输出小面的输出光束。 输出光束中的第一个被用作指向传感器外部的目标表面的探测光束,并且第二个输出光束用作指向光学检测器的监测光束,该光学检测器测量激光输出功率。 根据测量的输出功率,目标表面相对于传感器的运动被确定为通过来自目标表面的反射而返回到光腔的探测光束的一部分的自混合的函数。
