According to the working principles of backscattered electron imaging in scanning electron microscope, the backscattered electrons refer to the incident electrons that are reflected by atoms of the solid sample and the contrast of images are related to the atomic number distribution of sample surface atoms.

The accelerating voltages are adjustable, high- and low-vacuum modes are available, and secondary and backscattered electron imaging modes are possible.

To distinguish between the metal particles and the polymer matrix, backscattered electron imaging was used; the contrast results mostly from the differences in atomic masses of the constituents.
The method involved treating 90 [micro]m thick plywood sections, which had been cut transversely through the wood-coaling interface using a sliding microtome, with osmium tetroxide (Os[O.sub.4]) prior to examination with a field-emission scanning electron microscope (FE-SEM) operating in backscattered electron imaging (BEI) mode.

Hofstatter and his associates assessed bone mineral density (BMD) distribution using quantitative backscattered electron imaging, and bone biopsies were collected from nine premenopausal women with idiopathic osteoporosis.
Quantitative backscattered electron imaging is a relatively new technique for studying mineralization patterns, said Dr.
SEMs have two main imaging modes, secondary electron imaging (SEI) and backscattered electron imaging (BEI)--the former is the principal imaging mode, providing the best spatial resolution, and deriving contrast mainly from surface topography.
