Query: Organized Autotelescopes for Serendipitous Event Survey (OASES): design
  and performance   Organized Autotelescopes for Serendipitous Event Survey (OASES) is an optical
observation project that aims to detect and investigate stellar occultation
events by kilometer-sized trans-Neptunian objects (TNOs). In this project,
multiple low-cost observation systems for wide-field and high-speed photometry
were developed in order to detect rare and short-timescale stellar occultation
events. The observation system consists of commercial off-the-shelf $0.28 \
{\rm m}$ aperture $f/1.58$ optics providing a $2.3 \times 1.8$ square-degree
field of view. A commercial CMOS camera is coupled to the optics to obtain
full-frame imaging with a frame rate greater than $10 \ {\rm Hz}$. As of
September 2016, this project exploits two observation systems, which are
installed on Miyako Island, Okinawa, Japan. Recent improvements in CMOS
technology in terms of high-speed imaging and low readout noise mean that the
observation systems are capable of monitoring $\sim 2000$ stars in the Galactic
plane simultaneously with magnitudes down to ${\rm V} \sim 13.0$, providing
$\sim 20\%$ photometric precision in light curves with a sampling cadence of
$15.4 \ {\rm Hz}$. This number of monitored stars is larger than for any other
existing instruments for coordinated occultation surveys. In addition, a
precise time synchronization method needed for simultaneous occultation
detection is developed using faint meteors. The two OASES observation systems
are executing coordinated monitoring observations of a dense stellar field in
order to detect occultations by kilometer-sized TNOs for the first time.
