Microlens arrays are one of the key elements that are promising in autostereoscopic display, optical communication, wavefront sensing, integral imaging, etc. For example, microlens arrays are the critical components in integral imaging, which are used to collect and display images. In most cases, the image depth in integral imaging is limited due to the fixed focal length of the used microlens arrays.
