Various and unique techniques utilizing this spectrum have been employed to improve detection, each with its own merits. CIPS (Correlated interference polarization spectroscopy) is unique in how it provides high sensitivity along with high selectivity. The work presented builds on the achievements of CIPS as it was developed by BAH Holdings and its members. This Dissertation reports on modelling of CIPS and its constituents such as the electro-optical modulator. The development of the generator used in this system was also described. The mathematical model of the correlated interference polarization filter (cIPF), modulator, and etalon was derived and the parameters optimized. The optical response of the CIPS mathematical model to methane was presented. Several experiments were carried out to support the model and characterize critical properties of the modulator. A smart generator which drives the modulator was redesigned to be more efficient, robust and lower cost. Our work furthers the improvement of CIPS technology, in particular its limitations and potentials, and provides a framework for further studies and development specifically in two directions. It was shown that COMSOL can be used to develop new modulator designs. The technique for detection of other gases besides methane can utilize the same mathematical modeling framework."},{"label":"dcterms.available","value":"2017-09-20T16:52:41Z"},{"label":"dcterms.contributor","value":"Stanacevic, Milutin"},{"label":"dcterms.creator","value":"Cheng, William"},{"label":"dcterms.dateAccepted","value":"2017-09-20T16:52:41Z"},{"label":"dcterms.dateSubmitted","value":"2017-09-20T16:52:41Z"},{"label":"dcterms.description","value":"Department of Electrical Engineering"},{"label":"dcterms.extent","value":"97 pg."},{"label":"dcterms.format","value":"Application/PDF"},{"label":"dcterms.identifier","value":"http://hdl.handle.net/11401/77439"},{"label":"dcterms.issued","value":"2016-12-01"},{"label":"dcterms.language","value":"en_US"},{"label":"dcterms.provenance","value":"Made available in DSpace on 2017-09-20T16:52:41Z (GMT).
