An Undistorted View (image) The Optical Society Caption These images illustrate the performance between the aspheric and progressive mirror (top) and the flat and progressive mirror (bottom). In (a), the standard aspheric mirror is shown with a blue line to indicate the boundary between the two zones. This illustrates the distortion between the two zones. In (b), the progressive prescription developed by the researchers demonstrates the improved transition between zones, eliminating the blind spot while still giving an undistorted view of objects at a distance. (c) This is the standard flat side view mirror compared with (d) the wider field of view of the progressive mirror. Credit Credit: Optics Letters.
