The most common form of optoacoustic generation is thermoelasticity. Thermoelastic transduction is easy to implement and can be very broadband. However, its major drawback has always been poor conversion efficiency when a metallic film is used as the transducer. We have investigated two alternate structures for high efficiency, one based on a thin polymer film and the other using a two-dimensional nanostructure.

用于医学 3-D 超声成像的高频声音的光声生成。

最常见的光声生成形式是热弹性。热弹性转换很容易实现并且可以是非常宽的。然而，当使用金属薄膜作为换能器时，其主要缺点一直是转换效率差。我们研究了两种高效的替代结构，一种基于聚合物薄膜，另一种使用二维纳米结构。
