RETRO-REFLECTOR MICROARRAY AND APPLICATION THEREOF

摘要

The present invention relates to a retro-reflector microarray including a plurality of micro retro-reflectors arranged on a common plane. Each of the retro-reflectors is a concave corner cube consisting of three mutually orthogonal reflective surfaces. The concave corner cubes are the main reflecting elements of the microarray and make the reflected light anti-parallel to the incident light. The retro-reflector microarray can be used in optical detection instrument as an auxiliary element for remotely scanning fluorescence and Raman signals.
