A high-precision mechanical absolute-rotation sensor
Krishna Venkateswara, Charles A. Hagedorn, Matthew D. Turner +2
We have developed a mechanical absolute-rotation sensor capable of resolving ground rotation angle of less than 1 nrad above mHz and 0.2 nrad$/\sqrt{\text{H…
Picoradian deflection measurement with an interferometric quasi-autocollimator using weak value amplification
Matthew D. Turner, Charles A. Hagedorn, Stephan Schlamminger +1
We present an "interferometric quasi-autocollimator" that employs weak value amplification to measure angular deflections of a target mirror. The device has been designed to be ins…
Charge Management for Gravitational Wave Observatories using UV LEDs
S. E. Pollack, M. D. Turner, S. Schlamminger +2
Accumulation of electrical charge on the end mirrors of gravitational wave observatories, such as the space-based LISA mission and ground-based LIGO detectors, can become a source…
