In this webinar, we will highlight the challenges, opportunities and promising optical design solutions of high-performance AR near-to-eye-glasses as well as the applications of Optical Microscope such as biological imaging and defect inspection.

Optical microscopes have been widely used for biological imaging and defect inspection. The imaging field is a scaled replica of the specimen field in both amplitude and phase, while the phase is more sensitive than amplitude at the image plane relate to the optical property (thickness, refractive index) of the object. The traditional phase-contrast microscopy visualise phase shifts by transforming phase shift gradients into intensity variations, making it difficult to extract quantitative information. We have developed a quantitative phase imaging microscope, which can extract phase information for 3D surface profiler imaging with a vertical resolution of 10 nm, non-invasive label-free biological cells dry mass measurement, wafer defect inspection, etc. 

Augmented reality (AR) systems have the ‘see-through’ function that allows the eyes to view the real-world image and accept the virtual image at the same time. They are expected to revolutionize the entertainment, healthcare, communications and manufacturing industries, as well as many others. Despite their promise, near-to-eye AR display devices have yet to be embraced in the marketplace. The main limitations to these devices are their relatively small effective field of view, nonuniform illuminance and rainbow effect.
