TTF: A Flexible Approach to Narrowband Imaging
The Taurus Tunable Filter (TTF) is a tunable narrowband interference filter covering wavelengths from 6300Å to the sensitivity drop-off of conventional CCDs (∼ 9600 Å), although a blue ‘arm’ (3700−6500Å) is to be added by the end of 1997. The TTF offers monochromatic imaging at the cassegrain foci of both the Anglo-Australian and William Herschel Telescopes, with an adjustable passband of betwe...
متن کاملThe Taurus Tunable Filter Field Galaxy Survey: Sample Selection and Narrowband Number-counts
Recent evidence suggests a falling volume-averaged star-formation rate (SFR) over z < ∼ 1. It is not clear, however, the extent to which the selection of such samples influences the measurement of this quantity. Using the Taurus Tunable Filter (TTF) we have obtained an emission-line sample of faint star-forming galaxies over comparable lookback times: the TTF Field Galaxy Survey. By selecting t...
متن کاملDetection and Measurement from Narrowband Tunable Filter Scans
The past five years have seen a rapid rise in the use of tunable filters in many diverse fields of astronomy, through Taurus Tunable Filter (TTF) instruments at the AngloAustralian and William Herschel Telescopes. Over this time we have continually refined aspects of operation and developed a collection of special techniques to handle the data produced by these novel imaging instruments. In thi...
متن کاملWidely tunable monolithic narrowband grating filter for near-infrared radiation.
We propose a monolithic narrowband guided-mode grating filter in fused silica that is widely tunable in the near-IR wavelength region. Based on a recently demonstrated approach for a monolithic reflector comprising an encapsulated grating, we theoretically investigate such a device by means of rigorous modeling aimed at a narrow linewidth. It is demonstrated that upon a spatial variation of the...
متن کاملNarrowband, polarization insensitive all-fiber acousto-optic tunable bandpass filter.
We demonstrate an all-fiber acousto-optic tunable bandpass filter exhibiting narrow optical bandwidth and negligible polarization dependence by employing a novel ultraviolet (UV)-induced core-mode blocker written in a high numerical aperture (NA) fiber. It was demonstrated that the device had the measured 3-dB optical bandwidth of 0.65 nm, the polarization-dependent center-wavelength splitting ...
