我们设计、建造和测试了一台单光束光学捕获器，该仪器使用双电光偏转器(EOD)来引导陷阱在试件平面上。与基于声光偏转器(AOD)的传统仪器相比，基于EOD的陷阱显著提高了光吞吐量，并减少了偏转角度(指向)误差。这些属性赋予了更高的力和位置分辨率，使基于EOD的陷阱成为生物材料高精度纳米机械测量的一种有前途的替代方案。
We designed, constructed, and tested a single-beam optical trapping instrument employing twin electro-optic deflectors (EODs) to steer the trap in the specimen plane. Compared with traditional instruments based on acousto-optic deflectors (AODs), EOD-based traps offer a significant improvement in light throughput and a reduction in deflection-angle (pointing) errors. These attributes impart improved force and position resolution, making EOD-based traps a promising alternative for high-precision nanomechanical measurements of biomaterials.
