“…In 1966 Janine and Pierre Connes demonstrated remarkable spectra of planets demonstrably better than prior results which, they admitted, had been inferior or at best comparable to those obtained using conventional instruments. 44 One sympathetic commentator wrote that the results were 'far superior to that attained by conventional means, and all doubts about the importance of Fourier spectroscopy should be laid to rest by this work'. 45 Such evidence, deemed 'conclusive' by proponents, was nevertheless ignored by many spectroscopists still mistrustful of the indirectness of the technique.…”

“…The earlier calculations are of course theoretical, and in practice would be further conditioned by the geometry of instrument detector and other aspects of the instrument function. 6 …”

An active control system is described for the automatic alignment of the mirrors in a two-beam interferometer. From an initial unaligned position the active control system determines the degree of misalignment and adjusts the relative mirror positions accordingly. An embodiment of the system is described for a Michelson interferometer in which one of the mirrors is mounted upon three piezoelectric transducers ͑PZT͒ arranged so that they can both tilt and retard the mirror. Laser sources and corresponding photodetectors are also incorporated such that a control system can use the PZT actuators to produce a series of mirror movements relative to the fixed mirror and give a set of two-dimensional diffraction patterns-one for each of the laser photodetectors. Amplitude and phase information is extracted from these patterns which enables the control system to align the mirrors such that the diffraction pattern maxima is at the center of the instrument central photodetector. In a further stage of the control algorithm, the alignment accuracy is refined using information from the laser photodetectors during retardation of the mirror. In this manner, the initial mirror alignment, maintaining that alignment during retardation and diagnosis of possible misalignment, become part of a single active control technology for instrument alignment.

“…Another forty years passed before Peter B. Fellgett published results of the first numerical Fourier transform of an interferogram [57]. The first successful use of a Fourier transform spectrometer in astronomy came in 1966 when Janine and Pierre Connes used one to measure the near-infrared (NIR) spectrum of the atmosphere of Venus [69].…”

The Spectral and Photometric Imaging Receiver (SPIRE) is one of three scientific instruments on the European Space Agency's (ESAs) Herschel Space Observatory (HSO). The medium resolution spectroscopic capabilities of SPIRE are provided by an imaging Fourier transform spectrometer (IFTS). A software simulator of the SPIRE IFTS was written to generate realistic data products, making use of available qualification and test data. We present the design and implementation of the simulator. Component and end-to-end simulations were compared to results from the first
