A synthetic hologram is realized by J. Pastor as a replacement to an optically generated hologram in his study of holographic interferometry.

Jim Wyant’s work on computer-generated hologram testing is the origin of CGHs for interferometric null testing of aspheres.

Steve Arnold publishes a method for CGH grating fabrication using e-beam lithography, kicking off practical use of CGHs for interferometric testing.

Steve Arnold founds Diffraction International making CGHs available to optics fabricators around the world.

Dr. Jim Burge develops the equipment for and fabricates the largest CGHs in the world, the largest measuring 1.8 m, enabling large convex telescope mirror fabrication for a series of important research telescopes.

Drs. Chunyu Zhao and Jim Burge design the test system for the GMT (Giant Magellan Telescope) primary mirror segments. The null test set consisted of a 4 m fold sphere, a 0.75m fold sphere, and a CGH.

Drs. Chunyu Zhao and Jim Burge form AOM to commercialize the unique metrology solutions that they had developed at The University of Arizona.

AOM designs and fabricates a system alignment and calibration test CGH for the James Webb Space Telescope, Diffraction International supplies the primary mirror test CGHs.

AOM produces prototype CGHs and final mirror segment test CGHs for the Thirty Meter Telescope (TMT) supporting feasibility of the telescope concept and early design.

AOM produces CGHs for the LSST camera lenses, the largest camera on earth, supporting the optical system fabrication and alignment.

AOM opens a new headquarters in Tucson, AZ supporting increased CGH production volume, new R&D facilities, and new optomechanics products.

AOM opens an office in Rochester, NY, and initiates the Metrology Systems division, supporting metrology systems design and fabrication taking CGH metrology into new applications in optics production.

Marking a milestone and solidifying CGH metrology as a standard in the optics industry.

AOM’s headquarters in Tucson expands to a nearly 10,000-square-foot facility enabling us to enhance our production and engineering capacity.
