Boroscope and method of laser processing a component within an assembled apparatus using the boroscope

摘要

A boroscope (60) comprises a working head (68) having a first end (70) and a second end (72). A first optical fibre (74) extends through the boroscope (60) to a position between the first end (70) and the second end (72) of the working head (68). A second optical fibre (76) extends through the boroscope (60) to the second end (72) of the working head (68). A laser optical fibre (78) extends through the boroscope (60). At least one lens (80) is arranged between the first end (70) and the second end (72) of the working head (68) and a mirror (82) is gimballed (84) to the second end (72) of the working head (68). The laser optical fibre (78) directs laser light transmitted through the laser optical fibre (78) onto the lens (80) and then onto the mirror (82). A first LED (86) is arranged at a position between the first end (70) and the second end (72) of the working head (68) and a second LED (88) is arranged at the second end (72) of the working head (68) and an actuator devices (90, 92) adjust the position of the mirror (82).
