Interference fringes remain parallel and focus-spot diameter same. Scanning system proposed for laser velocimeter (laser Doppler anemometer) to maintain constant beam-crossing angle and beam-waist diameter maintaining beam waist locations at crossing points. As target fluid scanned, interference fringes formed by crossing beams remain parallel and the focus-spot diameter same. System allows accurate velocity profiles obtained in wind tunnels and other fluid flow systems.
