  • Patent number: 11914129
    Abstract: The present invention is directed toward a system and method for STED nanography, which reduces background noise. To remove background noise from a STED image, the polarization of the STED beam is altered from that used to obtain the original image. A polarized image is obtained. This polarized image can then be subtracted from the original image to remove noise inherent to the image.
