Ultrafast Micro-cantilever Displacement and Metrology with Blu-Ray Optical Pick-ups

该项目旨在开发一套多功能高性能纳米测量仪器，以廉价的商业组件为基础，满足工业对实时、纳米分辨率、大面积成像的低成本传感器和仪器的需求。无与伦比的带宽（> 100 MHz），分辨率（580 nm焦点和亚纳米位移灵敏度）和低成本的DVD和蓝光光学头使它们成为仪器仪表中计量元件的理想人选。它们将用于高速AFM （HS-AFM）和质量平衡悬臂运动，以及自动准直和加速度测量，旨在将世界上最快的HS-AFM捕获率和时间分辨率提高50倍。本项目开发的仪器的计量性能将进行评估。

The project aims to develop a suite of versatile high performance nanometrology instrumentation, based on cheap commercial components to satisfy industrial needs for low cost sensors and instrumentation for real-time, nano-resolution, large area imaging. The unrivalled bandwidth (> 100 MHz), resolution (580 nm focal spot and sub-nm displacement sensitivity) and low cost of DVD and Blu-ray optical heads makes them ideal candidates as metrology elements in instrumentation. They will be used for high-speed AFM (HS-AFM) and mass balance cantilever motion as well as for autocollimation and accelerometry with the aim of providing an x50 increase in world's fastest HS-AFM capture rate and temporal resolution. The metrological performance of instruments developed in this project will be evaluated.
