Real-time dispersion compensation in scanning interferometry

Not Accessible

Your library or personal account may give you access

Abstract

We propose and demonstrate a method of real-time dispersion compensation suitable for scanning interferometry and optical coherence tomography. Static grating tilt in a scanning frequency-domain optical delay line is shown to produce dispersion that is linearly proportional to scan position, and we use this property to achieve depth-dependent dispersion compensation during an interferometric scan through a dispersive sample.
