In this paper a method of taking widefield heterodyne inter- ferograms using a prototype modulated light camera is described. This custom CMOS modulated light camera (MLC) uses analogue quadrature demodulation at each pixel to output the phase and am...

Widefield ultrastable heterodyne interferometry using a custom CMOS modulated light camera (2011)
Conference Proceeding
Patel, R., Clark, M., & Achamfuo-Yeboah, S. (2011). Widefield ultrastable heterodyne interferometry using a custom CMOS modulated light camera.

A 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. © 2011...
