dc.description.abstract | Cryogenic cooling is a fundamental requirement for broadband far-infrared spectroscopic instrumentation to benefit from state-of-the-art far-infrared detectors. The precision to which the moving cryogenic components of the instrument can be measured and controlled affects its ability to recover the spectrum and exacts a low power robust position metrology system. This thesis explores a number of laser-based position metrology solutions and shows that a fibre-fed range-resolved interferometer meets the stringent precision and low power requirements of a metrology system for future space missions. Two cryogenic fibre-fed range-resoled interferometers are theoretically discussed and subsequently constructed; the first using the Clarke transform to decode three-phase signals, and the second based on sinusoidal laser frequency modulation. Experimental results of room and cryogenic (<4 K) temperature testing for both systems are presented. Lessons learned, suggested improvements, and the employment of a range-resolved interferometer for cryogenic accelerometry, lunar seismology, and other applications are discussed. | en_US |
