![]() Multi-variate statistical analysis is performed on these point sets to compare each set with one of a plurality of spectral signatures and a two dimensional map or image of the specimen area is made based on these comparisons.read more read lessĪbstract: A method for monitoring a region of a body surface includes recording at a first time a first multispectral digital image of the surface including the region, recording at a subsequent time a subsequent multispectral digital image of the surface including the region, and comparing the first and the subsequent images. The specimen is either repeatedly translated relative to the radiation source or imaged once or several times so that a signel set is derived from each elemental point on the area of the object to be analyzed in each spectral band of interest. POLYGON SUPERSCRIBE SERIESThe resulting radiation from the point is gathered by an optical system and detected either by a single wide band detector in the case of the series of monochromatic radiations or a group of frequency selective detectors in the case of polychromatic radiation, to develop a set of signals having values which are functions of properties of the point as analyzed at the different wavelengths. Abstract: To form a map of the characteristics of a microscopic specimen, the specimen is supported on a slide and a point on the specimen is subjected to either polychromatic radiation or a series of monochromatic radiations of varying wavelengths employing a condensing optical system. ![]()
