摘要

现有的 TAI 系统大多使用金属丝来校准其空间分辨率。然而，在这方面，对金属丝成像机制以及可能影响系统空间分辨率的金属丝参数设置的研究还不够充分。总体而言，对影响空间分辨率的因素缺乏了解。我们开发了一种由平行板辐照结构组成的 TAI 系统。结果表明，热声信号的来源是感应电动势产生的欧姆损耗。此外，感应电动势信号的脉冲宽度比系统激励信号的脉冲宽度窄，这对提高 TAI 的空间分辨率具有潜在的好处。

Standardization of metal coil configuration in thermoacoustic imaging.

Existing TAI systems mostly use metal wires to calibrate their spatial resolution. However, research on the imaging mechanism of the metal wire and the setting of the wire parameters that can affect the system's spatial resolution is not sufficient in this context. In general, there is a lack of understanding of the factors affecting spatial resolution. A TAI system, consisting of parallel plate irradiation structures has been developed. Results show that the source of the thermoacoustic signals is the ohmic loss generated by the induced electromotive force. Moreover, the pulse width of the induced electromotive force signal is narrower than that of the system excitation signal, which holds the potential benefits for improving the spatial resolution of the TAI.

期刊介绍： The Optical Society (OSA) publishes high-quality, peer-reviewed articles in its portfolio of journals, which serve the full breadth of the optics and photonics community. Optics Letters offers rapid dissemination of new results in all areas of optics with short, original, peer-reviewed communications. Optics Letters covers the latest research in optical science, including optical measurements, optical components and devices, atmospheric optics, biomedical optics, Fourier optics, integrated optics, optical processing, optoelectronics, lasers, nonlinear optics, optical storage and holography, optical coherence, polarization, quantum electronics, ultrafast optical phenomena, photonic crystals, and fiber optics. Criteria used in determining acceptability of contributions include newsworthiness to a substantial part of the optics community and the effect of rapid publication on the research of others. This journal, published twice each month, is where readers look for the latest discoveries in optics.
