In this talk I give the status of fabrication and testing of this system, and describe our plans to deploy it to a mountain top observatory site. I will also present future plans for larger multi-20
The primary goal of the LFAST prototype is to demonstrate a telescope design that can be rapidly and cost-effectively replicated to achieve a 1200 m 2 collecting area and match the
The projected cost of each unit telescope, when mass produced by the thousand, would then be approximately $8,000. The telescopes will be mounted in the open in groups of 20 located 12 m
Of all photonic technologies, optical fibers have been used most extensively in astronomical instrumentation. The most common application for fibers is for light transport from the focal plane of a
A telecentric lens is used to reimage the lens array at the entrance slits of two echelle spectrographs. Together, these two cover simultaneously the full 390 nm-1700 nm spectral range of the star being
She is currently working on the Large Fiber Array Spectroscopic Telescope (LFAST), focusing on the design, testing, and calibration of the LFAST fiber feed system, as well as science case planning.
For LOLA, a five fiber array was developed for the receiver telescope to maintain precise alignment for each of the 200/220 micron optical fibers collecting 1,064 nm wavelength light being
MARVEL consists of an array of four 80 cm telescopes linked through optical fibers to a single high-resolution echelle spectrograph, optimized for extreme-precision radial velocity
1. GOALS FOR LFAST The Large Fiber Array Spectrographic Telescope, LFAST, is a new type of telescope with very large collecting area for very high-resolution spectroscopy, designed for
This paper introduces the key concepts relating to the Fiber Array Solar Optical Telescope (FASOT) project. The various component parts are presented and the paper describes how these elements
The Large Fiber Array Spectroscopic Telescope (LFAST) concept involves the utilization of 2640 individual, 0.76 m “unit telescopes” to collect light from a target object. Through optical fibers, the
The Large Fiber Array Spectroscopy Telescope (LFAST) will combine thousands of small "unit telescopes" to create an array with collecting area greater than that of the GMT, TMT, or E-ELT, but
The Large Fiber Array Spectroscopic Telescope (LFAST) is designed to be a cost-efficient way to provide a large collecting area for spectroscopy by duplicating large numbers of small
Yunnan Astronomical Observatory, Chinese Academy of Sciences, Kunming, Yunnan 650011, China Abstract. This paper introduces the key concepts relating to the Fiber Array So-lar Optical Telescope
The Large Fiber Array Spectroscopic Telescope (LFAST) project seeks to construct large arrays of small, individual fiber-fed telescopes for very high resolution spectroscopy.
A fiber IFU with 8064 fibers is designed and manufactured for the Fiber Arrayed Solar Optical Telescope. 8064 fibers are divided to two 2D arrays for different polarization states and 12 pseudo
Considering that the unit telescope is to be replicated thousands of times, reducing the manufacturing cost per telescope is essential. The aim of the described design is to achieve this goal, with strong
An optical-fibre-based Integral Field Unit (IFU) has been developed for the Inter-University Centre for Astronomy and Astrophysics (IUCAA) Faint Object Spectrometer and Camera (IFOSC), the main
The importance and applied use of fibreoptics in astronomy has received rapidly growing attention in the past 5 years, particularly for instrumentation where the lightness, flexibility and simplicity of fibres,
The concept for the Large Fiber Array Spectroscopic Telescope (LFAST) (Angel et al, these proceedings) is to collect the light from a target object using thousands of individual, small, low-cost
Abstract The Large Fiber Array Spectroscopic Telescope (LFAST) concept involves the utilization of 2640 individual, 0.76 m “unit telescopes” to collect light from a target object. Through optical fibers,
An array of relatively smaller-sized telescopes electrically connected to form an aggregate aperture area equivalent to a single large telescope is a viable alternative to a monolithic
This paper describes the preliminary mechanical design and optomechanics of LFAST, the Large Fiber Array Spectroscopic Telescope. The 1,200 m<sup>2</sup> array comprises 132,
