Optical lenses for atomic beams
(2009)Superpositions of paraxial laser beam modes to generate atom-optical lenses based on the optical dipole force are investigated theoretically. Thin, wide, parabolic, cylindrical, and circular atom lenses with numerical ... -
Optical Measurement of Airborne Particles on Unmanned Aircraft
(2023-09-30)Aerosols and clouds are persistent causes of uncertainty in climate and weather models, which is due to their heterogeneous suspension and occurrence within the atmosphere, and complex interactions which are chaotic and ... -
Optical photometric GTC/OSIRIS observations of the young massive association Cygnus OB2
(2012-10-01)In order to fully understand the gravitational collapse of molecular clouds, the star formation process, and the evolution of circumstellar disks, these phenomena must be studied in different Galactic environments with a ... -
Optical properties of aerosol mixtures derived from sun-sky radiometry during SAMUM-2
(2011-09)The SAMUM-2 experiment took place in the Cape Verde islands in January-February 2008. The colocated ground-based and airborne instruments allow the study of desert dust optical and microphysical properties in a closure ... -
Optical properties of the Indo-Asian haze layer over the tropical Indian Ocean
(2003-01)[1] Multiwavelength backscatter and extinction profiling was performed with a unique aerosol Raman lidar at Hulhule (4degreesN, 73degreesE), Maldives, as part of the Indian Ocean Experiment (INDOEX) between February 1999 ... -
Optical rise-time measurements on KD*P transmission-line Pockels cells
(1978)A technique has been developed for determining the optical-transmission rise times of subnanosecond switching KD*P electro-optic modulators. Optical streak-camera data with 15-psec overall resolution and 30-psec resolution ... -
Optical Spectropolarimetry of Broad Line Active Galaxies
(Astronomical Society of the Pacific, 1999)We present new optical spectropolarimetry of two bright type 1 AGNs. The observations are part of a project on broad line active galaxies in which, through data analysis and modelling, we aim to identify the polarization ... -
Optical spectroscopy of the candidate luminous white dwarf in the young Large Magellanic Cloud cluster NGC 1818
(1999)An optical spectrum of the Elson et al. (1998) candidate luminous white dwarf in the young LMC cluster NGC1818 shows conclusively that it is not a degenerate star. A model atmosphere fit gives Teff 31,500K and log g 4.4, ... -
Optical waveguides by diffusion in II-VI compounds
(1972)Planar optical waveguides have been made by sealed ampoule diffusion of Cd and Se into ZnS and Cd into ZnSe. Three-dimensional diffused guides of Cd-diffused ZnSe have been made by using a masking layer of evaporated ... -
The optically unbiased GRB host (tough) survey. III : Redshift distribution
(2012-06-10)We present 10 new gamma-ray burst (GRB) redshifts and another five redshift limits based on host galaxy spectroscopy obtained as part of a large program conducted at the Very Large Telescope (VLT). The redshifts span the ... -
Optimal analog wavelet bases construction using hybrid optimization algorithm
(2016-12-01)An approach for the construction of optimal analog wavelet bases is presented. First, the definition of an analog wavelet is given. Based on the definition and the least-squares error criterion, a general framework for ... -
Optimal Control Design For Robust Fuzzy Friction Compensation in a Robot Joint
(2009)This paper presents a methodology for the compensation of nonlinear friction in a robot joint structure based on a fuzzy local modeling technique. To enhance the tracking performance of the robot joint, a dynamic model is ...
