Frequency-division-multiplexing technique for imaging metrology [PDF]
, 2014 An algorithm to multiplex multiple image captures simultaneously onto a single image sensor at full frame resolution was developed for imaging metrology. Parseval’s theorem was used to obtain the image intensity from image time-series of around typically

Optical PIV and LDV Comparisons of Internal Flow Investigations in SHF Impeller
International Journal of Rotating Machinery, 2006 The paper presents a comparison between two sets of experimental results in a centrifugal flow pump. The tested impeller is the so-called SHF impeller for which many experimental data have been continuously produced to built databases for CFD code ...

Visual Calibration for Multiview Laser Doppler Speed Sensing
Sensors, 2019 We present a novel calibration method for a multi-view laser Doppler speed sensing (MLDSS) system. In contrast with the traditional method where only the laser geometry is independently calibrated, the proposed method simultaneously optimizes all the ...

Uterine artery Doppler velocimetry with leiomyomas
Archives of Gynecology and Obstetrics, 1998 The study was conducted to establish a correlation between Doppler velocimetry in relation to uterine weight in any phase of the menstrual cycle and symptoms in women who have leiomyomas. Doppler velocimetry was carried out on both uterine arteries in 18 pre-menopausal women and one post-menopausal woman prior to undergoing abdominal hysterectomy at ...

Development and applications of two and three component particle image velocimetry techniques for simultaneous measurement in multi-phase flows and automative fuel sprays [PDF]
, 2010 The introduction of a new imaging approach for simultaneous multi-phase and multi-constituent velocity measurements is the main focus of this research. The proposed approach is based on the use of a single off-the-shelf colour camera which will enable ...
