摘要:
Disclosed herein is a system for an apodization mask composed of multi-walled carbon nanotubes (MWCNTs) for absorbing unwanted stray light. An apodization mask is a precise pattern or shape that is mathematically derived using light scattering measurement techniques to achieve optimal light absorption.Also disclosed herein is an apparatus for a duplex telescope with stray light suppressing capabilities comprising: a primary mirror for transmitting and receiving light; a secondary mirror for defocusing transmitted light onto the primary mirror and for focusing received light; a photodetector which receives light; a laser transmitter which transmits light; and an apodization mask for absorbing stray transmitted light.
