Automatic Online Calibration of Common-Path Fourier-Domain OCT

C11165: Automatic Online Calibration of Common-Path Fourier-Domain OCT

Value Proposition:

This technology presents a two stage process. Stage one obtains a series of calibrating polynomial coefficients that describes how the wavenumber in the spectrometer depends on the pixel index. Stage two determines the physical spacing between adjacent A-scan pixels for a particular scanning medium. Spectral data used for calibration is obtained from an arbitrary sample, which may have complicated internal structures, such as a biological specimen. The calibration can be done in real-time during the scanning procedure and therefore used to monitor the state of the OCT System during operation.

Technical Details:

Johns Hopkins University inventors report an automatic spectral calibration method for Fourier Domain optical coherence tomography (FD OCT) that does not require external light source or a commercial optics spectral analyzer.

Looking for Partners:

This technology simplifies and allows for real-time auto-calibration of FD OCT spectrometers.
