Abstract: Methods and apparatus are provided for optical coherence metrology or tomography across an extended area of an eye with improved registration. At least two optical coherence tomograms are acquired, with each tomogram containing data from regions of an anterior surface of the eye that are at least partially overlapping, and data from one or more deeper structures such as the retina or the anterior or posterior lens surfaces. The tomograms are then processed to register the data from the overlapping portions of the anterior surface regions, thereby registering the data from the deeper structures. In certain embodiments the reference arm of the apparatus comprises a compound reflector having at least two axially separated reflective surfaces for applying differential delays to different portions of the reference beam. The depth of field of the apparatus is thereby extended to enable measurement of eye length.

Abstract: A method comprises depositing a barrier layer on a dielectric layer to prevent oxidation of a metal layer to be deposited by electroplating due to an oxide present in the dielectric layer and depositing a doped liner layer on the barrier layer to bond with the metal layer to be deposited on the liner layer by the electroplating. The dopant forms a protective passivation layer on a surface of the liner layer and dissolves during the electroplating so that the metal layer deposited on the liner layer by the electroplating bonds with the liner layer. The dopant reacts with the dielectric layer and forms a layer of a compound between the barrier layer and the dielectric layer. The compound layer prevents oxidation of the barrier layer and the liner layer due to the oxide present in the dielectric layer and adheres the barrier layer to the dielectric layer.

Abstract: Described herein is a wavelength selective switch (WSS) type optical switching device (1) configured for switching input optical beams from input optical fiber ports (3, 5 and 7) to an output optical fiber port (9). Device (1) includes a wavelength dispersive grism element (13) for spatially dispersing the individual wavelength channels from an input optical beam in the direction of a second axis (y-axis).

Abstract: A system determines the transmission strength of the magnetic field signal. The magnetic field signal is transmitted from a first magnetic-sensor device to a second magnetic-sensor device. The system then determines a first projected distance between the first magnetic-sensor device and the second magnetic-sensor device.
