Paper Abstract

An overview of the activities in low-coherence interferometry (LCI) and optical coherence tomography (OCT) at the Industrial Materials Institute are presented. An innovative optical delay line using rhombic prisms is described. A few industrial applications are described: volume loss in a wear test, combination of LCI with laser-induced breakdown spectroscopy, and modification of an existing rheometer to increase its precision. Preliminary results related to the use of speckle to differentiate tissues and materials in OCT are presented. The speckle dimension is shown to be sensitive to low density of scatterers. An additional parameter extracted from the autocorrelation of speckle is also presented.
