Abstract
A light smoothing device for rendering a non uniform distribution of light more uniform especially suited for use in line scanning in combination with a light conducting rod which transmits light incident on its surface to its end faces for subsequent detection. The smoothing device has an optical passage with a reflecting interior surface an inlet to the passage and a detector at the other end of the passage. The passage ensures at least part of the light entering the inlet is reflected prior to incidence on the detector. A number of forms of optical passage are disclosed having various reflecting segments of convex, plain or concave curvature.
