摘要： A stereovision system is disclosed, which comprises: at least one diffractive optical element and an optical imaging device. Each of the diffractive optical element is used for allowing a first beam containing information relating to an object to pass through and thus transforming the same into a second beam containing information relating to the object. The optical imaging device is used for receiving the second beam so as to concentrate the energy thereof for forming an Mth-order diffraction image. By combining the aforesaid Mth-order diffraction image with another energy-concentrated Nth-order diffraction image, a series of images can be formed. Accordingly, by comparing the disparity between corresponding points in the series of images, the distance between the object and the diffractive optical element can be obtained. It is noted that the aforesaid M and N represent the order of diffraction.

摘要： A lens device with an adjustable focal length is provided. The lens device includes a non-conductive liquid droplet, which is surrounded by air or immiscible liquids. The non-conductive liquid droplet is placed on a bottom plate. The bottom plate includes a set of first electrodes. The set of first electrodes is disposed in such a way that the set of first electrodes are capable of being selectively biased to respectively create a first voltage potential difference between the liquid droplet and each of the set of first electrodes. With the first voltage potential differences, a dielectric force is induced, and the profile of the non-conductive liquid droplet is adjustable. Thus, the focal length of the lens is adjustable.
