Abstract
An angle-compensation sensor is described for measuring the shape of a dragonfly wing. In this method, the displacement is measured using an acousto-optic deflector and a quadrant position sensor. The displacem ent of a plastic plate that has a reflectivity of 4% is measured using this method. The displacement is then compared with that measured usi ng a linear gauge and is found to have a standard deviation of 8 mu m for a measured displacement range of 10 mm. The sensor is then applied to measure the shape of a dragonfly wing.
