Optical coherence microscopy using a reflective grating phase delay scanner

Summary from only given. We demonstrate optical coherence microscopy using a novel reflective grating phase modulator and a compact handheld probe. Our grating phase modulator is similar to reflective pulse stretchers and compressors previously developed for femtosecond pulse amplification. The reflective phase delay line can support broad spectral bandwidths and perform high speed phase modulation. This system design will enable high resolution, high speed OCM imaging at wavelengths which were previously inaccessible.
