A phase quadrature feedback interferometer using a two- mode He-Ne laser
A new feedback interferometer is developed with which not only the magnitude but also the sign of a phase change caused by a variation in the optical path can be measured. This is an important feature, for example, in plasma diagnostics. a He-Ke laser. The two interference signals can be separately detected by virtue of the orthogonal polarisation of the two axial modes of the laser without Bre...
متن کاملQuadrature phase-shift error analysis using a homodyne laser interferometer.
The influence of quadrature phase shift on the measured displacement error was experimentally investigated using a two-detector polarizing homodyne laser interferometer with a quadrature detection system. Common nonlinearities, including the phase-shift error, were determined and effectively corrected by a robust data-processing algorithm. The measured phase-shift error perfectly agrees with th...
متن کاملQuadrature phase detector using two-mode waveguides.
We present a novel design for quadrature phase detection utilizing two-mode optical waveguides for optical interferometric systems. A pair of interferometric signals having quadrature optical phase information can be obtained from the near-field and far-field patterns of a two-mode waveguide output. The operational principle is based on a pi/2 differential phase shift between two modal beams oc...
متن کاملA Magneto-Plasma-Dynamic Arcjet(MPDA) Plasma Density Measurements by Using Multi-Reflection Type He-Ne Laser Interferometer
A magneto-plasma dynamic arcjet(MPDA) is utilized as a high-enthalpy plasma source. Detailed measurement of plasma parameters in the vicinity of a MPDA is important to evaluate its performance. We have developed a multi-reflection type He-Ne laser interferometer for measurement of a high density plasma in the vicinity of a MPDA. We estimated the maximum value of electron density of 1.5� 10m nea...
متن کاملNanometric Displacement Measurement System Using Three-Longitudinal-Mode He-Ne Laser
In this paper, design and simulation of a nanometric displacement measurement system is discussed. The combination of the Doppler effect and interferometry method is being used. A stabilized three-longitudinalmode He-Ne laser with o A 6328 wavelength and cm 35 cavity length is used. Its primary and secondary beat frequencies are 428.60MHz, 429.27MHz, and 670kHz, respectively. Therefore, the max...
