　　专家介绍 :Matthew Radovan has a Bachelor of Science  degree from the U.C. Berkeley School of Engineering and is currently working as  an Astronomical Instrumentation Specialist at UC Observatories in Santa Cruz.  Early in his career he worked for the Brobeck Division of Maxwell Laboratories  managing the construction, installation and commissioning of the 1.4 GEV CAMD  Synchrotron for Louisiana State University (LSU). Currently he is working as a  Thirty Meter Telescope (TMT) Science Instruments Systems Engineer to refine the  conceptual design of the Multi-Object Broadband Imaging Echellette (MOBIE) which  will be the first-light optical spectrometer.

　　Abstract: The Multi-Object  Broadband Imaging Echellette (MOBIE) is the seeing-limited, visible-wavelength  imaging multi-object spectrograph (MOS) planned for first-light use on the  Thirty Meter Telescope (TMT).  The MOBIE project to  date has been a collaboration lead from the UC Observatories (Santa Cruz, CA),  and including the UH Institute for Astronomy (Oahu, HI), and the National  Astronomical Observatory of Japan (Tokyo, Japan). The conceptual design phase for the MOBIE  instrument was executed between 2009 and 2013.  It’s reported here on the conceptual  design of the instrument and its subsystems, including instrument and camera  optical designs, instrument control systems, atmospheric dispersion corrector,  slit-mask exchange system, collimator, dispersing and cross-dispersing optics,  refracting cameras, shutters, filter exchange systems, science detector  systems.
