Particle tracking stereomicroscopy in optical tweezers: control of trap shape [PDF]
, 2010 We present an optical system capable of generating stereoscopic images to track trapped particles in three dimensions. Two-dimensional particle tracking on each image yields three dimensional position information.

Implications of a 20-Hz Booster cycle-rate for Slip-stacking [PDF]
, 2014 We examine the potential impacts to slip-stacking from a change of the Booster cycle-rate from 15- to 20-Hz. We find that changing the Booster cycle-rate to 20-Hz would greatly increase the slip-stacking bucket area, while potentially requiring greater ...

Michelson Interferometry with the Keck I Telescope [PDF]
, 2000 We report the first use of Michelson interferometry on the Keck I telescope for diffraction-limited imaging in the near infrared JHK and L bands. By using an aperture mask located close to the f/25 secondary, the 10 m Keck primary mirror was transformed ...

Laser beam shaping in an apodizer with a rectangular serrated aperture
Компьютерная оптика, 2023 Profile transformation of a uniform monochromatic beam with a flat wavefront after the propagation through an apodizer comprising a square serrated aperture and a spatial filter is theoretically considered at the apodizer exit and behind it.

Photoacoustic tomography of a rat cerebral cortex with a ring-based ultrasonic virtual point detector [PDF]
, 2007 We image a rat cerebral cortex in situ by using a ring-based ultrasonic virtual point detector developed previously. Compared to the image generated by a finite-aperture detector, the image generated by the virtual point detector has a uniformly ...

Description and molecular phylogeny of a new and one known needle nematode of the genus Paralongidorus (Nematoda: Longidoridae) from grapevine in Portugal [PDF]
, 2018 A new and a known longidorid nematode, Paralongidorus lusitanicus n. sp. and Paralongidorus plesioepimikis, are described and illustrated from populations extracted from soil associated with grapevine (Vitis vinifera L.) from Escaroupim and Pó (central ...

Mechanistic analysis of TBM cutterhead-ground interaction under mud build-up effect
Frontiers in Earth ScienceIntroductionIn tunnel construction using TBMs, the complex mineral composition of strata and hydrogeological conditions often induce cutterhead mud build-up, which results in sharp increases in torque and thrust, thereby reducing excavation efficiency ...
