InactiveUS20150233701A1Enhanced OCT measurement and imagingReduce impactDiagnostics using vibrationsMaterial analysis by optical meansDifferential signalingConcentrations glucose
The invention teaches a method, apparatus and system for enhancing measurement and imaging using optical coherence tomography (OCT) by using a pressure wave, such as ultrasound, in conjunction with OCT to make measurements and generate images of a target. The pressure signal modulates the refractive index of the target at high speed, thereby disrupting the generation of a constant speckle noise pattern and thereby reducing speckle noise. The pressure signal can also be switched between at least two states at high speed which enables acquiring a high speed differential signal related weak scattering sites thereby enabling enhanced measurement and imaging of targets such as tissue. In the particular case of measurement of the concentration of glucose in tissue, differential signals enhance the accuracy with which the glucose concentration can be measured.
