Linear PAA Radiator with Frequency Scanning

2007 17th International Crimean Conference - Microwave & Telecommunication Technology, 2007
Antenna system with main lobe steering using generator frequency tuning is designed. The optimal radiator, having maximal angle-frequency senility is selected and optimized using minimum criteria of side lobe level.

Scanning linear polarimeter for aerosol sensing

SPIE Proceedings, 2006
An imaging polarimeter for sensing of aerosol scattering and other atmospheric phenomena has been constructed and tested. The instrument is a testbed for a multispectral system architecture, in which spectral channels are added in a modular fashion using dichroic beamspltters and dedicated detectors.

Acoustical holography with a scanned linear array

Journal of Applied Physics, 1972
A mechanically scanned linear detector array is analyzed for acoustical holography applications in which the sound transmitter is stationary. The theory of hologram formation is extended to include linear and nonlinear scanning as well as temporal reference phase.

A Modified Linear Scan Register Allocation Algorithm

2009 Sixth International Conference on Information Technology: New Generations, 2009
This paper proposes a global register allocation algorithm that makes decisions on register allocation based on the cost of spilling variables in linear scan allocation. The algorithm assumes registers are initially allocated based on linear scan algorithm.

Line-scan camera calibration: a robust linear approach

Applied Optics, 2020
Camera calibration requires three steps: estimation of correspondences between world and image coordinates, computation of a linear solution, and nonlinear optimization using the linear estimate as a starting point. The resulting accuracy depends mostly on the first and final steps.

Television field scan linearization

Journal of the British Institution of Radio Engineers, 1960
Although the design of a field timebase is based on well established principles and theory, there are many points at which there is considerable divergency between the theoretical and practical results. Foremost of these is that of calculating the parameters of linearizing networks, particularly of the feedback type.

Strengths and weaknesses of elimination voltammetry with linear scan

Talanta
Electrochemical methods have undergone many important developments initiated by efforts to increase the sensitivity, selectivity, and stability (S&S&S) and to understand the underlying electrode processes. To meet these goals, there are hardware solutions with applications of new technologies and materials, and software solutions utilizing existing ...

Scan Linearization for Resonant Optomechanical Systems

Imaging and Applied Optics 2014, 2014
Optomechanical characteristics of spiral scanning, Lissajous, and mixed resonant beam scanning systems are reviewed. An optical design for a scan lens that linearizes a fixed amplitude resonant beam scan is presented.

Precursor and Neutral Loss Scans in an RF Scanning Linear Quadrupole Ion Trap

Journal of the American Society for Mass Spectrometry, 2018
Methodology for performing precursor and neutral loss scans in an RF scanning linear quadrupole ion trap is described and compared to the unconventional ac frequency scan technique. In the RF scanning variant, precursor ions are mass selectively excited by a fixed frequency resonance excitation signal at low Mathieu q while the RF amplitude is ramped ...

Linearized Collinearity Equations for Scanned Data

Journal of the Surveying and Mapping Division, 1977
The collinearity equations, based upon modification of those common in conventional photogrammetry, must accommodate the continuous dynamic nature of the exterior orientation elements. Therefore, some types of functional behavior (polynomials, harmonics, etc.) must be assumed for those orientation elements.
