A phase-modulated interferometer for high-precision spectroscopy
We present a novel spectroscopic method based on a phase-modulated interferometer which is suitable for the high-precision measurement of absorption and index of refraction profiles. A comparison with competing methods, that is with interferometry and FM spectroscopy, is given. The combination of these two methods, the phase-modulated interferometer, is shown to be best suited for experiments a...
متن کاملPolarization-based balanced heterodyne detection method in a Sagnac interferometer for precision phase measurement.
We describe a balanced heterodyne detection method for a Sagnac interferometer that uses a polarization-dependent beam splitter. The signal and the local oscillator are orthogonally polarized components of a single laser beam, permitting the detection of the signal by subtraction of two photocurrents produced in appropriate polarization projections. Using this scheme, we experimentally demonstr...
متن کاملSelf-mixing Interferometer for Contactless Vibration Measurements
Self-mixing interferometer is a suitable tool for implementing industrial sensors, with the advantages of optical techniques, such as high accuracy and contactless operation, but at potential very-low cost. This paper describes some techniques recently developed for realizing vibration measurements, based on different signal elaborations and with different performances and applications. Particu...
متن کاملSpace Vector Modulation Based on Classification Method in Three-Phase Multi-Level Voltage Source Inverters
Pulse Width Modulation (PWM) techniques are commonly used to control the output voltage and current of DC to AC converters. Space Vector Modulation (SVM), of all PWM methods, has attracted attention because of its simplicity and desired properties in digital control of Three-Phase inverters. The main drawback of this PWM technique is
