Conventional cameras employed in fringe projection systems result in multiple measurements and limit depth acquisition to low dynamic range objects. We propose three-dimensional imagers employing a multichannel micropolarizer camera to deliver enhanced fringe visibility for high dynamic range objects and snapshot acquisition for fast moving objects
