Abstract

1428970 Optical apparatus MARCONI CO Ltd 7 June 1973 [15 July 1972] 33242/72 Heading G2J An arrangement for amplifying the deflection of a light beam 5, 6 travelling in a first medium e.g. air, comprises a second medium 2 of higher R. 1. e.g. "Perspex" (Registered Trade Mark) having a first surface 3 concave over the deflectable range of the beam 5, 6 and a second surface 4 beyond which is a third medium e.g. air of lower R.1. than medium 2. Surface 4 is such that the beam is received at at least one extremity of deflection at substantially critical angle to provide an emergent beam 7, 8 having an amplified deflection. Two bodies of medium 2 may be placed in series for two-stage amplification Fig. 5 (not shown). A further two may be oriented to scan an enlarged area Fig. 6
