Abstract

Diffusing light modulated by focused ultrasound (FUS) or acousto optic (AO) sensing is a hybrid technique that utilizes ultrasound features, such as, deep penetration, localize and precise spatial resolution, to surpass optical scattering limitations in optical sensing and maintain the original optical contrast. In this paper, we compare the acousto-optic (AO) signal amplitude when using three different light sources; long coherence, laser diode (LD), and light emitting diode (LED). In recent years, there has been a growing trend towards the use of LEDs and laser diode LDs in optical applications because of their compact and small size, ease of use, safety features, and cost-effectiveness. Aim of this paper is to examine the capability of LDs and LEDs to be used in AO sensing. We evaluated differences in the tagging efficiency using detection of AO signal amplitude metrics. The results showed that particularly LDs are also capable of providing acceptable tagging efficiency in AO-based sensing compared with long coherent lasers and can be beneficial option for use in AO based techniques.
