  • TMT Wide-Field Optical Spectrometer (WFOS) Review
  • The TMT Wide-Field Optical Spectrometer (WFOS) team held a key review on May 2-3. An external committee reviewed the work performed during the Opto-Mechanical Design and Requirements (OMDR) phase, which focused on the end-to-end optical design configuration, key mechanical design elements and the designs of the two cameras. NAOJ has been contributing to the camera designs.

  • TMT's Telescope Structure Final Subsystem Design Review Completed
  • The last of three final design review presentations for the TMT's telescope structure was successfully conducted in December 2016. The design work presented at the review was led by NAOJ, through their subcontractor MELCO. The committee has since concluded that the design of all telescope subsystems is ready to enter its final phase.

  • TMT exhibition won an Innovation Award on CEATEC JAPAN 2015
  • Mitsubishi Electric received the CEATEC INNOVATION AWARDS 2015 in the Digital Imaging Category for their work on TMT. They displayed a TMT scale model and the 3DCG animation from NAOJ to introduce their work on the Telescope structure on CEATEC (Combined Exhibition of Advanced Technologies) JAPAN, the largest annual consumer electronics and IT exhibition in Japan. The CEATEC INNOVATION AWARDS are presented to the most excellent technology, product and service exhibits at CEATEC JAPAN, which are carefully scrutinized by a panel of American IT and consumer electronics journalists covering the show. Mr. Hubert Nguyen, Chairman of the Panel of Judges, praised this project saying “Understanding what happens in space will also help us understand our world better. That's why we are giving an Innovation Award to Mitsubishi Electric for their amazing work.”
