Abstract

A method for gated imaging using an adaptive depth of field is provided herein. The method includes obtaining boundary conditions associated with a preliminary depth of field (DOF) parameters in a scene; illuminating the scene, using a light source, with a pulsed light beam, based on the specified boundary conditions; controlling sensor array parameters based on the boundary conditions; capturing, using the sensor array, one or more images of the scene, wherein the capturing is based on one or more exposures synchronized with the pulsed light beam, to achieve gated images of the scene in accordance with the boundary conditions associated with the DOF parameters; analyzing at least one of the captured images, using data processing algorithms, to yield updated DOF parameters; and repeating the above stages with updated sensor array parameters and updated light source parameters, based on the updated DOF parameters and updated boundary conditions.
