Abstract
A technique for automatic detection of abnormalities, particularly pathology, in biomedical specimens. Light transmittance or reflectance data over a large number of wavelengths for numerous samples are correlated mathematically with conventional clinical results to select test wavelengths and constants for a correlation equation. Optical instrumentation with an analog or digital computer applies the resulting correlation equation to the spectral data on a given specimen at the test wavelengths to determine quantitatively the presence of the abnormality.
