ABSTRACT:
The invention relates to a fiber optic light fixture which can generate a thin sheet of incoherent light with sharply defined surfaces that, when projected on the face of an object, produces a line or band of light with sharp, crisp edges. The light fixture elongates the light in the direction of the thin sheet and condenses the light in a direction normal to the thin sheet. One characteristic of the fixture is that objects placed within the beam of light near the fixture do not cast shadows on objects off in the distance.
