Noncontact optical sensor for bone fracture diagnostics

Biomed Opt Express. 2015 Feb 3;6(3):651-7. doi: 10.1364/BOE.6.000651. eCollection 2015 Mar 1.

Abstract

We present the first steps of a device suitable for detection of broken and cracked bones. The approach is based on temporal tracking of back reflected secondary speckle patterns generated when illuminating the limb with a laser and while applying periodic pressure stimulation via a loud speaker. Preliminary experiments are included showing the validity of the proposed device for detection of damaged bones.
