The problems encountered in measuring the wing of insects using a conventional triangulation method are concluded. An alternative scheme solves these problems by measuring the wing shape using forward diffusion. The system parameters and measurement results of a dragonfly wing are given. The output signals from conventional system and this improved system are compared. The improved scheme, which excels the conventional triangulation method in measuring a transparent surface, is approved in the experiment for a practical measuring of the shape of a dragonfly wing.
