Abstract: Provided herein are systems, methods and apparatuses for an in vivo surgical device that uses tomographic imaging to guide the process of surgical incisions for cell, biologics and drug delivery; the image guided system guides the process of delivery with comprehensive real-time processing with the ability to seal the location of delivery and offer laser-tissue modification via a co-aligned tissue modification beam on tissue without tissue damage to adjacent critical or delicate structures.

Abstract: An apparatus and method for detecting defects in an additive manufacturing process is provided. An example method may include depositing a first layer of material, depositing a second layer of material in at least partial contact with the first layer of material, and inducing a phase change between the first and second layers of material via an energy beam. Further, the method may include directing an electromagnetic radiation beam to at least a portion of a subsurface interface between the first and second layers, measuring radiation returned from the material, and based on the measured radiation, determining a location of a refractive index gradient within the material.

Abstract: Disclosed herein is a system and a method for controlling laser energy deposition in order to normalize post-sintering temperatures is presented. Sensors provide feedback for in-situ control of laser power to reduce the influence the pre-sintering thermal profile has on the post-sintering temperatures. By actively controlling the laser during its scanning, the post-sintering temperatures can be more accurately controlled, resulting in mechanical and geometric improvements in part quality.

Abstract: Exemplary embodiments include an apparatus and method for performing angle-resolved imaging of scattering samples such as tissue, including the use of a pathlength multiplexing element.
