Beamforming and hardware design for a multichannel front-end integrated circuit for real-time 3D catheter-based ultrasonic imaging
(SPIE-Int Soc Optical Engineering, 2006)We are working on integrating front-end electronics with the ultrasound transducer array for real-time 3D ultrasound imaging systems. We achieve this integration by flip-chip bonding a two-dimensional transducer array to ... -
CMUT-based volumetric ultrasonic imaging array design for forward looking ICE and IVUS applications
(SPIE-Int Soc Optical Engineering, 2013)Designing a mechanically flexible catheter based volumetric ultrasonic imaging device for intravascular and intracardiac imaging is challenging due to small transducer area and limited number of cables. With a few parallel ... -
Coordination in building an observatory: A case study of Eastern Anatolian Observatory (DAG)
(SPIE-Int Soc Optical Engineering, 2018)Eastern Anatolian Observatory (DAG) is designed to build on one of the summits of Palandoken Mountains in Erzurum, Turkey, at an altitude of 3,151 meters. The building is under construction since 2015 and expected to be ... -
DAG 4m telescope: assembly, integration and testing
(SPIE-Int Soc Optical Engineering, 2018-07-06)AMOS with EIE as a main subcontractor, was awarded a contract in November 2014 for the design, manufacturing and installation of a 4m-class telescope for the Turkish Eastern Anatolia Observatory (DAG) situated at 3170 m ... -
DAG-TGI: Turbulence generator instrument for DAG (Eastern Anatolia Observatory)
(SPIE-Int Soc Optical Engineering, 2018-07-18)DAG (East Anatolia Observatory) Telescope has 4 m mirror with active optics (a0) and adaptive optics (AO) systems. In order to evaluate DAG's focal plane instruments and their installation, calibration and laboratory ... -
Design of a derotator for the 4 m DAG telescope
(SPIE-Int Soc Optical Engineering, 2016-08-09)This paper Silt our work on the design of a field derotator for the adaptive optics instruments platform of DAG (Dogu Anadolu Cozier vi), a new 4 in telescope for astronomical observations near the city of krzurum, l'urkey. ... -
A flexible adaptive optics concept for general purpose high angular resolution science on the DAG 4m telescope
(SPIE-Int Soc Optical Engineering, 2018)Thanks to the availability of high actuator density deformable mirrors (ALPAO 468 DM), the high versatility of the pyramid wavefront sensor and above all, the venue of essentially no noise EMCCD detectors, it becomes ... -
A generic point error model for TLS derived point clouds
(SPIE-Int Soc Optical Engineering, 2017-06-26)This work aims at developing a generic and anisotropic point error model, which is capable of computing magnitude and direction of a priori random errors, described in the form of error ellipsoids for each individual point ... -
Integrated opto-dynamic modeling of the 4-m DAG telescope image quality performance
(SPIE-Int Soc Optical Engineering, 2016)The Turkish DAG 4-m telescope is currently through the final design stage. It is to be located on a 3170 m mountain top in Eastern Anatolia. The telescope will be a state-of-The art device, alt-Az mount with active primary ... -
Linear filtering of image subbands for low complexity postprocessing of decoded color images
(SPIE-Int Soc Optical Engineering, 2005)In [1], image adaptive linear minimum mean squared error (LMMSE) filtering was proposed as an enhancement layer color image coding technique that exploited the statistical dependencies among the luminance/chrominance or ... -
A miniature real-time volumetric ultrasound imaging system
(SPIE-Int Soc Optical Engineering, 2005)Progress made in the development of a miniature real-time volumetric ultrasound imaging system is presented. This system is targeted for use in a 5-mm endoscopic channel and will provide real-time, 30-mm deep, volumetric ... -
