Abstract: A system for authenticating an object includes at least one laser configured for interacting with a tag, the tag comprising structural changes to the object, the structural changes being responsive to terahertz electromagnetic waves. The system may also include a processor configured to (i) receive electromagnetic wave data resulting from interaction of the terahertz electromagnetic waves with the structural changes, (ii) compare the electromagnetic wave data to a reference standard, (iii) determine that the object is authentic in response to the electromagnetic wave data meeting the reference standard, and (iv) determine that the object is not authentic in response to the electromagnetic wave data not meeting the reference standard. A system for reading a tag of an object is further provided.

Abstract: A system and method for generating a three-dimensional image of a sample. The system comprises a platform configured to support the sample, a laser source configured to output a laser beam to remove material from the sample, a microscope imaging system, and a controller communicatively coupled to the laser source and the microscope imaging system. The controller is configured to (a) acquire height data of a surface of the sample with the microscope imaging system, (b) generate a mask based on the height data of the surface of the sample, the mask providing a laser cutting pattern for the sample, (c) acquire an image and a height map of the surface of the sample with the microscope imaging system, (d) activate the laser source to generate a laser beam to delayer the sample based on the mask, and repeat steps (a)-(d) to generate a three-dimensional image of the sample.
