Abstract: A spatio-temporal profilometer performs time-resolved spatial profilometry and includes a substrate, a tapered optical collimator waveguide, a fluid channel, and a light-fluid interaction volume. The tapered optical collimator waveguide receives diverging light, internally reflects it, and collimates it. The fluid channel receives a fluid comprising microparticles and communicates the microparticles into the fluid channel. The light-fluid interaction volume is disposed in the fluid channel and provided by an overlap within the fluid channel of the collimated light from the tapered optical collimator waveguide and the fluid. The spatio-temporal profilometer produces product light from the collimated light in response to the microparticles interacting with the collimated light in the light-fluid interaction volume from which is determined a spatial and temporal profile of microparticles in the fluid channel.

Abstract: A process for removing aberrations in an acquired image from imperfect imaging optics includes: acquiring an acquired image of an object with an imperfect imaging system that includes an imperfect imaging optic, the acquired image including a plurality of pixels; producing a prior that includes an expectation of data for the object; determining a pixel-by-pixel uncertainty of the acquired image; determining a total transfer function of the acquired image from the prior and the acquired image; and determining a data vector from the total transfer function and the acquired image to remove aberrations from the acquired image.

Abstract: Embodiments of the present invention relate to apparatus and methods for dual comb spectroscopy with deterministic stepping and scanning of temporal pulse offset. In one embodiment, the present invention relates to a novel dual-comb spectroscopy including mode locked robust Er-combs and digital phase-locking electronics for step scanning between the two frequency combs and applicable to any phase-locked dual-comb system. The tight phase control of the DCS source allows for the control of temporal offset between the two comb pulses during measurements.

Abstract: Apparatus in accordance with embodiments of the present invention provide torque realization via electrical measurements traceable to the revised International Standard of Units (SI). Torque can be realized via a conversion of linear mechanism of a Kibble balance to a rotational mechanism. Embodiments of the present invention relates to an electronic torque realization apparatus including a rotor for holding permanent magnets and an encoder scale ring and for coupling to a torque device, a stator for characterizing physical aspects of a torque tool and for generating the torque on rotor in conjunction with the permanent magnets, a base plate for mounting a first end of rotor and stator, a cantilever for supporting a second end of rotor and for maintaining axial alignment, a bearing assembly for supporting the motion of rotor, and encoder for recording the angular position of rotor.
