Large deflection micromechanical scanning mirrors for linear scans and pattern generation
IEEE Journal of Selected Topics in Quantum Electronics, 2000An electrostatically driven silicon micro scanning mirror (MSM) for one-dimensional (1-D) and two-dimensional (2-D) deflection of light is presented. A special configuration of the driving electrodes allows the use of small electrode gaps without restricting the deflection of the plate geometrically.

Linear image sensor optimized for fast color scanning
IEEE Transactions on Consumer Electronics, 1992Scanners are common computer peripherals. The authors describe a linear sensor for scanners generating high resolution, photographic quality, and colorimetrically correct data at high speed. The sensor consists of three independent charge-coupled-device (CCD) imagers, one for each of the three colors, integrated on a single die.

Linear mass scans in quadrupole ion traps using the inverse Mathieu q scan
Rapid Communications in Mass Spectrometry, 2016Rationale Secular frequency scanning is a method of mass selectively scanning ions out of a quadrupole ion trap by linearly ramping the frequency of the resonance ejection signal through ion secular frequencies at constant rf amplitude and ...

Basic Scanning Techniques of Linear EUS
2012The linear echoendoscope (EG-530UT) has a curved transducer facing on one side. This provides a 120° sector scanning ultrasound view. The working channel opens just above the transducer and the instruments (commonly needle) can be seen on the ultrasound view. This permits EUS guided biopsies and interventions to be performed.

Precursor and Neutral Loss Scans in an RF Scanning Linear Quadrupole Ion Trap
Journal of the American Society for Mass Spectrometry, 2018Methodology 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 ...

Acoustical holography with a scanned linear array
Journal of Applied Physics, 1972A 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.

Wide-angle scanning optical linear phased array
2015 IEEE International Conference on Microwaves, Communications, Antennas and Electronic Systems (COMCAS), 2015An optical linear phased array designed for a wide-angle scanning is presented. To facilitate a wide-scanning capability while avoiding grating lobes, the inter-element spacing smaller than one wavelength is selected. A patch antenna radiating element coupled to a Silicon dielectric waveguide is designed.

Clinical Orthopaedics and Related Research, 1992
In Europe, the use of ultrasonography has become a routine procedure for the detection of hip dislocations and dysplasias; clinical and historical data alone are not fully reliable. Under the right conditions, ultrasonographic examination of the hip can reliably detect hip joints in need of treatment.
