In a method of producing an anti-reflective surface, instead of etching subwavelength structures directly onto the substrate, a thin film layer of topcoat is deposited onto the surface of the substrate, and the anti-reflective surface is created by etching the structures into the topcoat. Because the thin film can be applied to substrates made of a large number of different materials, only common etching recipes need to be developed for a few thin film materials. The present method overcomes the shortcoming that existing methods of etching structures directly on a substrate would require a different etching recipe for each substrate made of a different material.

A system and method of producing energetic laser pulses suitable for multi-photon microscopy, in which laser pulses from an ultrafast pump source operating at greater than 40 MHz repetition rate are directed onto an optical cavity, where the pulses build-up to a higher energy inside of that cavity over the period of many pulses. After the intra-cavity pulses achieve sufficient energy, an active element inside of the cavity switches out the enhanced light pulse with a reduced a repetition rate relative to the pump source. The increased pulse energy and reduced repetition rate will enable the pump source, originally designed for two-photon microscopy, to perform new imaging modalities, such as deep, in-vivo, three-photon microscopy.

The conical ball cone bearing is a high load and reduced pressure kinematic or fixed thrust bearing that allows for a greater load carrying capacity with a reduced contact pressure to be obtained in a smaller package. This bearing maximizes the contact radius over the needed angular translation to reduce the contact pressure. This has two advantages in a kinematic system. First, the reduced contact pressure increases the maximum load the bearing can hold prior to surface failure. Second, the reduced contact pressure reduces the friction on the kinematic contacts, allowing the kinematic system to move more freely and operate with a smoother movement and improved stability.

Abrégé
This disclosure relates to combined frequency and angle compounding for speckle reduction in ultrasound imaging. Such combined frequency and angle compounding can result in a multiplicative speckle reduction compared to using either frequency compounding or angle compounding alone. Compounding methods of this disclosure can make use of the full aperture of the ultrasound probe when acquiring individual images, hence there can be no compromise in resolution. In disclosed embodiments, ultrasound images can be obtained while an ultrasound probe is moving and the relative position and orientation of the ultrasound images can be determined from a measurement of the position and orientation of the ultrasound probe. Certain embodiments can correct for the movement and distortion of an object being imaged during the image acquisition.

Wide bandwidth optical detector comprising plural phase tuning elements respectively receiving optical signals from directional couplers
Disclosed are the method and system to derive the wavelength/frequency information covering wide wavelength or frequency range. Its practical applications include both fixed wavelength optical signal and wide bandwidth tunable or non-tunable optical signal, where the wavelength/frequency information is necessary for optical signal calibration, control, and monitoring, optical communications, and data processing. The approach has a “self-compensation” feature which is preferred to improve the accuracy of the extracted wavelength or frequency information even though there are components in the system having strong wavelength or frequency dependence in the wide wavelength or frequency range. The method is generic which can be realized in free space, fiber, or photonic integrated circuit (PIC).

MEMS tunable VCSEL powered swept source OCT for 3D metrology applications
Disclosed is an optical probe system that is capable of high speed, high precision, and high resolution 3D digitalization of engineered objects. The 3D dimensional data of the engineered object is measured using a swept source optical coherence tomography system with improved speed, spatial resolutions, and depth range. Also disclosed is a type of coordinate measurement machine (CMM) that is capable of performing high speed, high resolution, and non-contact measurement of engineered objects. The mechanic stylus in the touch-trigger probe of a conventional CMM is replaced with an optical stylus with reconfigurable diameter and length. The distance from the center of the optical stylus to the measurement probe is optically adjusted to match the height of the object to be measured quickly, which eliminates one dimensional movement of the probe and greatly improves the productivity.

Higher-order dispersion compensating pulse shaper via amplitude spectral filtering and nonlinear phase accumulation
A method of pulse shaping using spectral filtering, positive chirp, and self-phase modulation to control the accumulated higher-order phase terms of the spectral phase. This pulse shaping method has particular advantage in fiber chirped pulse amplification (FCPA) systems, where there are two effects: (1) an offsetting of the fourth order phase via nonlinear phase accumulation, allowing for a higher Strehl ratio (i.e., a cleaner pulse), higher peak power pulse and (2) enabling power scaling to higher pulse energies without the increased nonlinear phase accumulation leading to pulse breakup. This technique can be used both in a passive system with no amplification to clean up an existing pulse, and in an amplifier system to enable higher performance operation (shorter pulses, cleaner pulses, higher energy pulses).

Use of electronically controlled polarization elements for the initiation and optimization of laser mode-locking
Apparatus for modelocking a fiber laser cavity includes two variable retarder assemblies and a polarizing element. The variable retarder assemblies each have two electronically addressable elements and one fixed element. The first variable retarder assembly prepares a polarization state suitable for NPE modelocking to be launched into the fiber, and the second variable retarder assembly controls the polarization state after exiting the fiber, before being incident on the polarizing element. A control system controls the electronically addressable phase retarders in order to create and modify conditions for modelocking the fiber laser.

A system for generating a series of reducing intensity laser pulses from an ultrafast pulsed laser source. The reducing intensity series of pulses is equally temporally spaced between pulses from the laser source. The repeating series of reducing intensity laser pulses is fed to a microscope for imaging. The microscope is capable of detecting the fluorescence from a sample generated by each pulse in the series. The data is processed using knowledge of the pulse intensity, location on the test sample, and amount of fluorescence measured to create an increased dynamic range of the image relative to what can be obtained in a normal two-photon imaging system.
