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.

该项目旨在开发一套多功能的高性能纳米测量仪器，基于廉价的商业组件，以满足工业对低成本传感器和实时，纳米分辨率，大面积成像仪器的需求。DVD和蓝光光学头无与伦比的带宽（> 100 MHz）、分辨率（580 nm焦斑和亚nm位移灵敏度）和低成本使其成为仪器仪表中计量元件的理想选择。它们将用于高速原子力显微镜（HS-AFM）和质量平衡悬臂梁运动，以及自准直和加速度测量，目的是提供世界上最快的HS-AFM捕获速率和时间分辨率增加50倍。将对本项目中开发的仪器的性能进行评估。
