Fiber-optic interferometric sensors have emerged as essential tools in precision measurement, utilising the interference of coherent light to detect minute displacements and variations in physical ...

[brmarcum] takes us back to analog building block basics with his Frequency Modulation and Demodulation tutorial. Frequency Modulation (FM) sounds simple at first, but understanding the electronics ...

WE have examined further the anomalous fluctuations in the superconducting bolometers previously reported by Andrews, Milton and Desorbo 1, and find that, in part, such fluctuations are due to the ...
