Abstract
An apparatus (100) for measuring not only the reflected radiation but also the fluorescence emission of a textile sample (106), which includes a presentation subsystem (102) having a viewing window (108). A radiation subsystem (114) has a tunable radiation source (120) for directing a desired radiation (122) having a wavelength range and an intensity through the viewing window (108) toward the sample (106), and thereby causing the sample (106) to produce a fluorescence (124). A sensing subsystem (126) has an imager (130) for capturing the reflected radiation and fluorescence (124) in an array of pixels. A control subsystem (132) has a processor (136) for controlling the presentation subsystem (102), the radiation subsystem (114), and the sensing subsystem (126), and creates a reflected radiation and fluorescence image containing both spectral information and spatial information in regard to the reflected radiation and fluorescence (124) of the sample (106).
