A Variable Phase-Shift Frequency-Modulated Oscillator

Proceedings of the IRE, 1949
The theory of operation of a phase-shift type of oscillator is discussed briefly. This oscillator consists of a broad-band amplifier, the output of which is fed back to the input through an electronic phase-shifting circuit. The instantaneous frequency is controlled by the phase shift through this latter circuit.

Phase-shift-locked interferometer with a wavelength-modulated laser diode

Applied Optics, 2003
A phase-shift-locked interferometer has been constructed for distance measurement. A phase shift produced by sawtooth-current modulation of a laser diode is locked to a phase difference preset by polarization optics that consists of a quarter-wave plate and polarizers through an electrical feedback technique.

Non-Photic Modulation of Phase Shifts to Long Light Pulses

Journal of Biological Rhythms, 2007
Circadian rhythms can be reset by both photic and non-photic stimuli. Recent studies have used long light exposure to produce photic phase shifts or to enhance non-photic phase shifts. The presence or absence of light can also influence the expression of locomotor rhythms through masking; light during the night attenuates locomotor activity, while ...

Phase Shift Modulations for Stable, Oscillatory, Traveling, Strongly Nonlinear Waves

Studies in Applied Mathematics, 1991
Oscillatory dispersive waves propagating in a slowly varying medium are analyzed for Klein‐Gordon equations with perturbations. The method of multiple scales is extended to include two fast scales, the usual traveling‐wave phase and time, in order to allow initial conditions not usually permitted.
