Confocal microscopy by aperture correlation

OPT LETT 21 (23): 1879-1881 DEC 1 1996 Wilson T, Juskaitis R, Neil MAA, et al.

Most confocal microscopes do not produce images in real time with nonlaser light sources. The tandemscanning confocal microscope does produce such images but, because the pinhole apertures of the Nipkov diskmust be placed far apart to reduce cross talk between neighboring pinholes, only 1% or less of the light availablefor imaging is used. We show that, by using aperture correlation techniques and relaxing the requirement toobtain a pure confocal image directly, one can obtain real-time confocal images with a dramatically increased(25% or even 50%) light budget.
