本文介绍了一种用于光声层析成像的法布里-珀罗超声传感器，该传感器采用Ta_2O_5和SiO_2制成的非吸湿介质镜。该传感器提供高达36 MHz的平坦频率响应、低噪声等效压力（70 Pa）、高达20 MHz的近全向响应以及用于近红外照明的光学透明性。建立了一个数值模型，预测其频率响应，并通过实验验证了结果。获取人手掌的图像以证明体内成像能力。(C)2017美国光学学会
A Fabry - Perot ultrasound sensor with nonhygroscopic dielectric mirrors made out of Ta2O5 and SiO2 for use in photoacoustic tomography is described. The sensor offers flat frequency response up to 36 MHz, low noiseequivalent pressure (70 Pa), and near-omnidirectional response up to 20 MHz as well as optical transparency for near-infrared illumination. A numerical model was developed to predict its frequency response, and the results were validated experimentally. An image of the human palm was acquired to demonstrate in vivo imaging capabilities.
