TL;DR: Hyper Suprime-Cam (HSC) as mentioned in this paper is an 870 Mega pixel prime focus camera for the 8.2 m Subaru telescope that can produce a sharp image of 0.25 arc-sec FWHM in r-band over the entire 1.5 degree (in diameter) field of view.

TL;DR: Hyper Suprime-Cam (HSC) as discussed by the authors is the next generation wide-field imager for the prime focus of Subaru Telescope, which is scheduled to receive its first light in 2011.

TL;DR: In this paper, a coherent light coupling device is provided with a distributor that distributes a laser beam outputted from a laser light source to a plurality of laser beams, an amplifier that amplifies the laser beams respectively distributed by the distributor, a converging part that converges the laser beam amplified by the amplifier, and a light intensity distribution control unit that controls the intensity distribution in the laser beacons converged by the converger.

TL;DR: An overview of the preliminary design of the Telescope Structure System (STR) of Thirty Meter Telescope (TMT) is presented, including the performing of dynamic response analyses of the STR system under the time dependent acceleration profile of seven major earthquakes.
