We have developed many kinds of optical methods to measure the insect flight. For example, a beating force measurement method reduces the uncertainty caused by air turbulence; a flow measurement using a frame straddling technique decreases the interval between exposures of the flow;extracting the weak distorted fringes on the dragonfly wing by a correlation algorithm; measuring the camber deformation of a dragonfly wing using projected comb fringe without hypothesizing that the wing is a rigid plate. By measuring the beating force, wing kinematics and flow, simutantously, we can analyze the relationship among many flight parameters.
