A multiple height-transfer interferometric technique was developed to increase the absolute distance measurement capability of a metrology system that uses a tunable laser. Using multiple accurately calibrated reference heights, this technique relaxe

Three-dimensional (3D) shape reconstructions and metrology measurements are often limited by depth-of-field constraints. Current focus-detection-based techniques are insufficient to profile out-of-focus 3D objects with high axial accuracy. Extended-f

A line scan interferometer, which comprises a visible supercontinuum source coupled to Fourier domain Michelson interferometer, is used to obtain 3D images of ~300 μm high solder balls on a semiconductor die with 125 nm axial and 15 μm lateral reso

Tunable lasers are used in optical metrology, but their intrinsic tuning accuracy is sometimes inadequate and an external wavemeter is then required to measure the wavelength more accurately. In this paper, we present the design of a discrete step wa

Objects can be imaged if passed through a field formed by the interference of a Hermite-Gaussian (modal) laser beam with a spatial offset reference beam. The light intensity scattered by the object is electronically detected and spatially recorded on

We present a new technology allowing on-chip integration of a micro-resonator and its energy source for fundamental studies and commercial applications. As a proof-of-concept we demonstrate four-wave mixing and Raman lines.

Existing interferometric techniques for imaging through scattering media require coherent illumination and stationary targets. We introduce a new grating interferometer that is capable of imaging an incoherently illuminated target regardless of wheth
