Abstract: A device that uses two intensity modulated frequency combs to measure distances with high precision and high data acquisition rate without any moving parts and without length ambiguity that is inherent conventional ranging based on two frequency combs. A modulation signal having a repetition rate identical to the repetition rate difference between the two combs is used to do a direct time-of-flight length measurement, hence avoiding the given length ambiguity while harvesting the increased precision of the dual-comb approach.

Abstract: A method for manufacturing hybrid optical coatings and hybrid mirror assemblies, including: a) providing a first optical coating having layers of alternating high and low refractive indices of crystalline materials on a first host substrate via an epitaxial growth technique; b) providing a second optical coating having layers of alternating high and low refractive indices of dielectric materials on a second host substrate via a physical vapor deposition (PVD) technique; c) directly bonding the first optical coating to the second optical coating; and d) removing the first host substrate.
