Abstract

The most successful methods for speckle reduction in Optical Coherence Tomography (OCT) are based on deformation of the wavefront used in scanning. Here, a simple method is presented where the wavefront is distorted by lateral translation of the lens between the 2D galvo-scanner and sample. The report demonstrates that the method can be implemented with a small, fast piezoelectric transducer. Up to 33% improvement in speckle contrast ratio (SCR) of B-scan OCT images is demonstrated.
