TTF: a flexible approach to narrowband imaging [PDF]
, 1997 The Taurus Tunable Filter (TTF) is a tunable narrowband interference filter covering wavelengths from 6300 A to the sensitivity drop-off of conventional CCDs (9600 A), although a blue `arm' (3700-6500 A) is to be added by the end of 1997.

Taurus Tunable Filter -- seven years of observing
, 2003 The Taurus Tunable Filter (TTF) has now been in regular use for seven years on the Anglo-Australian Telescope. The instrument was also used for three years (1996--1999) on the William Herschel Telescope.

Continuously Tunable Microwave Photonic Notch Filter With a Complex Coefficient
IEEE Photonics Journal, 2011 This paper presents a continuously tunable microwave photonic notch filter with a complex coefficient. The complex coefficient is generated using a radio-frequency (RF) phase shifter that consists of a dual-parallel Mach-Zehnder modulator (DPMZM) and a ...
