在本文中,我们报告了一种新的双轴微扫描镜(WIMSM)使用扭转和弯曲的BoPET(双轴取向聚对苯二甲酸乙二醇酯)铰链。通过扭转铰链,快轴在空气中的谐振频率为265 Hz,在水中的谐振频率为172 Hz。通过扭转铰链,快轴在空气中的谐振频率为265 Hz,在水中的谐振频率为172 Hz。在弯曲铰链的情况下,慢轴具有小于1Hz的谐振频率。当两个轴以其谐振频率驱动时,获得具有最大扫描范围的密集光栅扫描图案。为了演示,在水中的3D体积超声显微镜进行与新的WIMSM。
In this paper, we report a new two-axis micro scanning mirror (WIMSM) using torsional and bending BoPET (biaxially-oriented polyethylene terephthalate) hinges. With a torsional hinge, the fast axis has a resonance frequency of 265 Hz in air and 172 Hz in water. With a torsional hinge, the fast axis has a resonance frequency of 265 Hz in air and 172 Hz in water. With a bending hinge, the slow axis has a resonance frequency less than 1 Hz. When the two axes are driven at their resonance frequencies, a dense raster scanning pattern with a maximal scanning range is obtained. For demonstration, 3D volumetric ultrasound microscopy in water is conducted with the new WIMSM.
