Phase-shifting (Sagnac) interferometer with external phase control
Applied Optics, 2005A novel ring configuration for phase-shifting interferometry with external phase-shifting control is presented. The device is a polarization (ring) interferometer, in which the reference and test arms are parts of the same collimated beam. The key point is to manage the polarization of the light such that orthogonal linear polarizations describe ...

Random phase-shifting interferometry without accurately controlling or calibrating the phase shifts
Optics Letters, 2009A random phase-shifting interferometry insensitive to environmental noises is proposed. The relationship between intensity and phase in each pixel is obtained from a large amount of phase-shifting interferograms. In the phase-solving algorithm, the phase shift step length is not taken as a parameter, but the temporal intensity maximum and minimum in ...

Thyristor-controlled phase-shifting devices
Russian Electrical Engineering, 2014Phase-shifting devices with thyristor regulation intended for the constant control of power overflows in power-supply networks with parametric and regime nonuniformity have been developed. The phase shift of the output voltage is regulated using a high-voltage thyristor key, which ensures the speed of the device.

A digital controlled oscillator based on controlled phase shifting
IEEE Transactions on Circuits and Systems, 1989A new architecture for a digitally controlled oscillator is presented. It is based on a controlled phase shifting principle and shows phase and frequency characteristics comparable to those of simple accumulator-type rate-multiplier-based circuits. An important feature of the proposed configuration is the possibility of a high clock frequency, also ...

Phase controllability improvement for alternating phase shift mask
SPIE Proceedings, 1998An alternating phase shift masks can improve resolution and lithographic latitude. However, Alt-PSMs have not yet become practical because of difficulty in their tight phase and defect control. In this paper, we focused on how to control both phase uniformity and phase mean value of etched quartz shifters. We found that a material of a dry-etching tale

Digital control for phase shift converter
Proceedings of 2012 IEEE International Conference on Automation, Quality and Testing, Robotics, 2012The development of intelligent microgrids with renewable energy sources increased significantly nowadays. The present paper examines and compares analog and digital control of a bidirectional phase shift converter in order to find out which is best suited to be used in intelligent microgrid applications.

Voltage-Controlled Phase Shift of Triangular Waves
IEEE Transactions on Instrumentation and Measurement, 1973A principle is described whereby an instantaneous voltage proportional to the phase shift of the outputs of two triangular-wave generators can be obtained. By controlling one of the triangular-wave generators with the difference between this voltage and a reference voltage, a certain phase difference between the triangular waves is obtained which can ...
