Profile Summary

Expertise in unconventional optics, laser beam characterization and propagation, matrix optics, and polarization control. Inventor of Phase-Space Beam Analizer(TM) VariSpot(R), VariFoc(TM) and VariPol(TM) unconventional optical systems, all manufactured by ASTiGMAT. Developed new methods/systems to measure M^2, and introduced two new beam invariants, generalizing the M^2: the intrinsic astigmatism, a, and the effective M^4, now included in ISO 11146-1,2,3 standards. Founder and President of ASTiGMAT, a consulting, R&D, and OEM company. Developer of laser and optics-related ISO standards.
