Single beam interferometric angle measurement
We present a new application of the Nomarski interferometer, to measure the angular position of a parallel laser beam with interfero-metric precision. In our experimental realization we reach a resolution of 3 × 10 −9 rad (6 × 10 −4 ′′) for 1 kHz bandwidth in a 2 × 10 −2 rad (1 •) range. This alternative to the optical lever technique features absolute calibration, independence of the sensitivi...

We present an application of a quadrature phase interferometer to the measurement of the angular position of a parallel laser beam with interferometric precision. In our experimental realization we reach a resolution of 6.8 × 10 −10 rad (1.4 × 10 −4 ′′) for 1 kHz bandwidth in a 2 × 10 −2 rad (1 •) range. This alternative to the optical lever technique features absolute calibration, independence...

متن کاملUltrasensitive beam deflection measurement via interferometric weak value amplification.
We report on the use of an interferometric weak value technique to amplify very small transverse deflections of an optical beam. By entangling the beam's transverse degrees of freedom with the which-path states of a Sagnac interferometer, it is possible to realize an optical amplifier for polarization independent deflections. The theory for the interferometric weak value amplification method is...
متن کاملMeasurement of Colliding Beam Parameters with Wide Angle Beamstrahlung
where the N1,2 and σx,y,z are the beam populations and spatial dimensions at any given time t (which is a run-time variable of order one hour). This formula becomes rather complex over time. Particles are deflected by the other beam at each crossing, significantly affecting the Twiss matrix of the machine. The beam currents Ni(t) decrease due to beam lifetime also causing the machine’s Twiss ma...
