Embodiments of the present invention relate a nondiffracting beam detection module for generating three-dimensional image data that has a surface layer having a first surface and a light transmissive region, a microaxicon, and a light detector. The microaxicon receives light through the light transmissive region from outside the first surface and generates one or more detection nondiffracting beams based on the received light. The light detector receives the nondiffracting beams and generates three-dimensional image data associated with an object located outside the first surface based on the one or more detection nondiffracting beams received. In some cases, the light detector can localize a three-dimensional position on the object associated with each detection nondiffracting beam received. In other cases, the light detector can determine perspective projections based on the detection nondiffracting beams received and generates the three-dimensional image data, using tomography, based on the determined perspective projections.
