Widefield ultrastable heterodyne interferometry using a custom CMOS modulated light cameraTools Patel, Rikesh, Clark, Matt and Achamfuo-Yeboah, Samuel (2011) Widefield ultrastable heterodyne interferometry using a custom CMOS modulated light camera. In: Applied Industrial Optics: Spectroscopy, Imaging and Metrology 2011, 10–14 July 2011, Toronto, Canada. Full text not available from this repository.AbstractA method of detecting optical heterodyne interference fringes using a custom CMOS modulated light camera array has been developed. Widefield phase images are generated using quadrature demodulation and are kept stable using a feedback system.
