Image processing of multispectral x-ray photoelectron spectroscopy images

A new direct imaging photoelectron microscope has been demonstrated at the Stanford Synchrotron Radiation Laboratory. Data are obtained in the form of spectrally resolved images with a lateral resolution of <5 μ. The microscope produces a series of projected images with 64×64 picture elements. These images are recorded digitally and represent a very large data set. Image statistical methods have been used to reduce and present the image information.
