3D light scanning macrography

The technique of 3D light scanning macrography permits the non-invasive sur face scanning of small specimens at magnifications up to 200x. Obviating bo th the problem of limited depth of field inherent to conventional close-up macrophotography and the metallic coating required by scanning electron mic roscopy, 3D light scanning macrography provides three-dimensional digital i mages of intact specimens without the loss of colour, texture and transpare ncy information. This newly developed technique offers a versatile, portabl e and cost-efficient method for the non-invasive digital and photographic d ocumentation of small objects. Computer controlled device operation and dig ital image acquisition facilitate fast and accurate quantitative morphometr ic investigations. and the technique offers a broad field of research and e ducational applications in biological, medical and materials sciences.
