    Development of a handheld compression optical coherence elastography probe with a disposable stress sensor

    Optical coherence elastography (OCE) is a functional extension of optical coherence tomography (OCT). OCE measures a sample’s deformation under force stimuli. Compression is often used to generate the force stimuli in OCE. In this Letter, we report the development of a handheld quantitative compression OCE probe with a novel stress senor, dedicated to measuring the force. The stress sensor consists of a circular glass window and a metal ring which are connected with polyurethane spokes. This sensor is mounted on the tip of the OCT sample arm as an imaging window, so that the force applied to the sample ...
