Abstract
A detecting apparatus for detecting an object includes at least a screen, at least a detecting unit and at least a holding unit. The screen is partial light-permeable and has a first surface and an opposite second surface. The object is disposed adjacent to the first surface of the screen. The detecting unit is disposed corresponding to the object and located adjacent to the second surface of the screen. The holding unit holds the relative distances between the screen, the object and the detecting unit. The detecting unit captures the image of the second surface of the screen so as to calculate the optical field distribution of the object. The detecting apparatus can measure the optical field distribution of an object quickly and has the advantages of low cost and high accuracy.
