There is described an inspection device for inspecting a slot of a gas turbine engine. The inspection device comprises: an insert for insertion into the slot; a plurality of imaging devices coupled to the insert; and a processor. The insert is movable along a longitudinal axis of the slot. Each of the plurality of imaging devices is positioned adjacent an external surface of the insert and is configured to capture an image of a portion of the slot adjacent the imaging device. The processor is configured to receive data corresponding to the images captured by the plurality of imaging devices. There is also described a method of inspecting a slot using the inspection device.

Inspection devices and methods of inspecting a slot

A probe for iridocorneal angle imaging of an eye, the probe comprising: a distal end having a corneal contact surface; a camera having an imaging lens at the distal end and an imaging axis orthogonal to the corneal contact surface; and at least two illumination sources, each illumination source having an illumination axis at an angle to the corneal contact surface such that the imaging axis and the illumination axes converge in the eye.

An imaging probe () for use in measuring surface roughness by angular speckle correlation is shown. The imaging probe comprises a first illumination fibre () to illuminate a sample location () on a surface, and having an input end for coupling of coherent light into the fibre, and an output end cleaved at an angle &#x3b8;, a second illumination fibre () to illuminate the sample location on the surface, and having an input end for coupling of coherent light into the fibre, and an output end cleaved at an angle &#x3b8;that is different from &#x3b8;, and an image transmission system () for transmission of a speckle pattern caused by illumination of the sample location on the surface by coherent light from either the first illumination fibre or the second illumination fibre.
