[3Dp1-7L] Controlling Speckle and Resolution of Reconstructed Images by Vibrating Multimode Optical Fiber with a Cylindrical Piezoelectric Transducer in Electro-Holography
Electro-holography, Speckle, Multimode optical fiber, Piezoelectric transducer
To reduce the speckle of reconstructed images in electro-holography, reducing laser coherence is essential. We developed a device to vibrate a multimode optical fiber using a cylindrical piezoelectric transducer to reduce coherence. In addition to speckle, the resolution can be electronically controlled with this device.
