Scanning Michelson interferometer for imaging surface acoustic wave fields.
A scanning homodyne Michelson interferometer is constructed for two-dimensional imaging of high-frequency surface acoustic wave (SAW) fields in SAW devices. The interferometer possesses a sensitivity of ~10(-5)nm/ radicalHz , and it is capable of directly measuring SAW's with frequencies ranging from 0.5 MHz up to 1 GHz. The fast scheme used for locating the optimum operation point of the inter...
متن کاملAMI : Augmented Michelson Interferometer
Experiments in optics are essential for learning and understanding physical phenomena. The problem with these experiments is that they are generally time consuming for both their construction and their maintenance, potentially dangerous through the use of laser sources, and often expensive due to high technology optical components. We propose to simulate such experiments by way of hybrid system...
متن کاملGuided magnonic Michelson interferometer
Magnonics is an emerging field with potential applications in classical and quantum information processing. Freely propagating magnons in two-dimensional media are subject to dispersion, which limits their effective range and utility as information carriers. We show the design of a confining magnonic waveguide created by two surface current carrying wires placed above a spin-sheet, which can be...
متن کاملInvestigations of Light with a Michelson Interferometer
In this paper, we present several applications of the Michelson Interferometer in analyzing monochromatic, dichromatic, and white light. First, the wavelength of the mercury green line is determined to be 540 ± 36theo ± 10sys nm by measuring the fringe separation. An estimate was made by counting fringes passing a reference point as a platform mounted mirror was moved translationally with a pre...
متن کاملLength sensing and control of a Michelson interferometer with power recycling and twin signal recycling cavities.
The techniques of power recycling and signal recycling have proven as key concepts to increase the sensitivity of large-scale gravitational wave detectors by independent resonant enhancement of light power and signal sidebands within the interferometer. Developing the latter concept further, twin signal recycling was proposed as an alternative to conventional detuned signal recycling. Twin sign...
