From: Ultrasound-modulated optical glucose sensing using a 1645 nm laser
Photographs of a vessel-mimicking phantom with an empty (a) and filled (b) gelatin-TiO2 background embedding a tubing. The red and green areas indicate the diffused light and ultrasound propagation, respectively. The blue arrows and dotted area indicate the pathway of the glucose solution. The magenta area indicates the localized sensing region.
