Publication number: 20130221211Abstract: A phase noise detection apparatus comprises a laser beam, an optical resonator coupled thereto at a coupling point and a photodetector receiving light from the laser beam. The laser beam and the resonator coupled thereto convert phase noise of light transported by the laser beam prior to the coupling point into intensity noise of light transported by the laser beam thereafter. Intensity noise is converted into an electrical signal by the photodetector. The electrical signal is sent through a first signal path and a second signal path such that the first signal path transports a signal substantially proportional to the intensity noise, which is integrated in an integrator in the second path. Relative gain of the two signal paths can be adjusted and the overall gain of the signal path is preferably such that the optical phase modulator at least partially cancels said phase noise in the optical domain.Type: ApplicationFiled: October 13, 2011Publication date: August 29, 2013Applicant: RWTH AachenInventor: Jeremy Witzens

Patent number: 8242779Abstract: A nuclear magnetic resonance (NMR) method for detecting hydrogen peroxide includes stimulating a spin signal in a liquid sample in a static magnetic field by exciting the sample with a first electromagnetic pulse having a frequency corresponding to a hydrogen NMR frequency; after a first time period, refocusing the spin signal by a series of second electromagnetic pulses also having the NMR-corresponding frequency and separated by a first echo time, while sampling a first train of spin signals; and refocusing the spin signal by a series of third electromagnetic pulses having the NMR-corresponding frequency and separated by a second echo time while sampling a second train of spin signals, the second echo time different from the first echo time. First and second spin-spin relaxation times are derived from the trains of spin signals, and a quotient of the spin-spin relaxation times indicates the presence of hydrogen peroxide.Type: GrantFiled: October 13, 2009Date of Patent: August 14, 2012Assignee: RWTH AachenInventors: Bernhard Blumich, Lisandro Buljabasich Gentiletti, Federico Casanova, Juan Francisco Perlo

Publication number: 20110241667Abstract: A method for performing magnetic resonance measurements on a sample includes applying a first predetermined number of pulse trains for excitation, each pulse train having a constant amplitude and including a second predetermined number of pulses spaced by a predetermined time interval. The pulse trains are modulated by a bent function. After each pulse, data is sampled. Preferably a square number of pulses is generated being constant in power, and the Walsh transform of the sequence of their phases is constant in power, so that the power of the excitation in time and frequency domain is constant. The method can reduce power requirements and may permit undercutting specific absorption rate (SAR) limits due to the small excitation power necessary to create time signals with reasonable signal to noise ratio.Type: ApplicationFiled: October 8, 2009Publication date: October 6, 2011Applicants: RWTH AACHEN, UNIVERSITY COLLEGE DUBLIN, NATIONAL UNIBVERSITY OF IRELANDInventors: Bernhard Blümich, Marcus Greferath, Eimear Byrne, Qingxia Gong
