Flicker stereo alternates two pictures (∼ 1 frame/sec.) of the same structure with views tilted 6° ± 1° about a vertical axis—Natural appearing stereo visualization results. A flicker stereo program to be used for viewing with a personal computer (PC) was developed by the authors. The two images are installed, adjusted for superposition and then alternated on the computer monitor or computer projection system. Flicker stereo can be applied to micrographs from the optical microscope, SEM, TEM, pictures or line drawings. Flicker stereo provides simultaneous three dimensional viewing for several individuals without special viewers, projection systems and/or glasses. Different flicker images may be retrieved and viewed on a PC in rapid succession. Flicker stereo facilitates technical discussion between collaborators and provides a convenient approach for 3D visualization by audiences using a digital LCD projection. The program is available to readers.
