Compact holographic optical element-based electronic speckle pattern interferometer for rotation and vibration measurements

Compact holographic optical element-based electronic speckle pattern interferometer for rotation and vibration measurements

An out-of-plane sensitive electronic speckle pattern interferometer (ESPI) using holographic optical elements (HOEs) for studying rotations and vibrations is presented. Phase stepping is implemented by modulating the wavelength of the laser diode in a path length imbalanced interferometer. The time...
