Multi-wavelength Digital Holography using Acousto-Optics

Not Accessible

Your library or personal account may give you access

Abstract

With an acousto-optic frequency shift of 80 MHz, a synthetic wavelength in the order of meters can be achieved. Accurate surface maps are obtained for a multi-depth object using multi-wavelength digital holography without using phase-unwrapping.
