Performance Assessment of the KASI-Deep Rolling Imaging Fast-optics Telescope pathfinder
Woowon Byun, Jongwan Ko, Yunjong Kim +14
In a CDM universe, most galaxies evolve by mergers and accretions, leaving faint and/or diffuse structures, such as tidal streams and stellar halos. Although these structures ar…
Transformable Reflective Telescope for optical testing and education
Woojin Park, Soojong Pak, Geon Hee Kim +6
We propose and experimentally demonstrate the Transformable Reflective Telescope (TRT) Kit for educational purposes and for performing various optical tests with a single kit. The…
Flight model characterization of the wide-field off-axis telescope for the MATS satellite
Woojin Park, Arvid Hammar, Soojong Pak +6
We present optical characterization, calibration, and performance tests of the Mesospheric Airglow/Aerosol Tomography Spectroscopy (MATS) satellite, which for the first time for a…
Development of Linear Astigmatism Free -- Three Mirror System (LAF-TMS)
Woojin Park, Seunghyuk Chang, Jae Hyuk Lim +10
We present the development of Linear Astigmatism Free - Three Mirror System (LAF-TMS). This is a prototype of an off-axis telescope that enables very wide field of view (FoV) infra…
Photometry Transformation from RGB Bayer Filter System to Johnson-Cousins BVR Filter System
Woojin Park, Soojong Pak, Hyunjin Shim +4
The RGB Bayer filter system consists of a mosaic of R, G, and B filters on the grid of the photo sensors which typical commercial DSLR (Digital Single Lens Reflex) cameras and CCD…
Camera for QUasars in EArly uNiverse (CQUEAN)
Won-Kee Park, Soojong Pak, Myungshin Im +6
We describe the overall characteristics and the performance of an optical CCD camera system, Camera for QUasars in EArly uNiverse (CQUEAN), which is being used at the 2.1 m Otto St…
Auto-Guiding System for CQUEAN (Camera for QUasars in EArly uNiverse)
Eunbin Kim, Won-Kee Park, Hyeonju Jeong +8
To perform imaging observation of optically red objects such as high redshift quasars and brown dwarfs, the Center for the Exploration of the Origin of the Universe (CEOU) recently…
Proto-Model of an Infrared Wide-Field Off-Axis Telescope
Sanghyuk Kim, Soojong Pak, Seunghyuk Chang +5
We develop a proto-model of an off-axis reflective telescope for infrared wide-field observations based on the design of Schwarzschild-Chang type telescope. With only two mirrors,…
