Stereo SEM
To collecting a stereo-pair in an SEM, you simply collect one image with the sample perpendicular to the detector (i.e. lying flat) and then a second image with the sample tilted, say 7⁰, towards or away from the detector. The images can then be viewed using a stereo-viewer or used to construct an anaglyph for which red/blue glasses are required to see the stereo effect.
