Depth-sensing technology using a negative microlens array

In this study, an optical depth-sensing system whose focus distance was equal to its object distance was constructed by using a lens with a shortened depth of field. In addition to a mechanical control lens that captured two-dimensional images, a set of negative microlens array films used to shorten...
