Abstract
A protective shroud is provided for enveloping light radiating from a light emitter used with a sensor system for mapping of a railway track. The protective shroud includes: a rigid body having a frame and at least one opaque panel connected to the frame, the rigid body defining at least a first portion of a light radiation zone; a skirt formed of high density fibers extending from adjacent a bottom edge of the at least one opaque panel to adjacent a ground surface; at least one light emitter connected to the rigid body adjacent a top edge of the rigid body to emit light radiation into the light radiation zone; and at least one sensor connected to the rigid body adjacent the top edge of the rigid body to sense the light emitted from the at least one light emitter.
