Photoacoustic measurement of localized optical dichroism in chiral crystals

In this communication, we present a novel method to measure local optical dichroism (OD) in opaque crystal powder suspensions using photoacoustic (PA) effect. Our method is based upon the novel laser speckle contrast technique, in combination with a simple statistical approach, we were able to measure the OD of chiral crystals suspensions under completely random orientation.

In this study, a new method was introduced to measure local optical dichroism in opaque crystal powder suspensions using the photoacoustic effect. The method, based on laser speckle contrast technique and a simple statistical approach, allows for the measurement of optical dichroism in chiral crystal suspensions with completely random orientation.
