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.

本研究针对昆虫运动的特点，研究开发了测量昆虫运动，特别是自由飞行昆虫运动的光学方法，包括：风洞中扇翅力的测量，解决高灵敏度光学测量的抗干扰问题；帧头帧尾流场测量方法，解决由CCD拍摄帧频导致的测量速度低的问题；调制相关算法，解决透明翅膀上散射光较弱问题；梳状条纹投影法，解决翅膀弓形变形测量问题，不需要以往的翅膀刚性平板或刚性条杆假设；多参数的综合测量，解决各参数间的相位匹配问题。
