Web1. nov 2024 · In general, the reflectance images (RIs) of effective wavelengths (EWs) provide image information, and the reflectance value of each pixel in these images contains spectral information; thus, RIs can provide spectral and image information (Wang et al., 2024). Moreover, the RIs of EWs can be easily obtained by customised and simplified optical ... Web1. nov 2024 · Reflectance Transformation Imaging (RTI) is an imaging technique used to capture the surface appearance of objects. A set of images of the subject are taken using a fixed viewpoint and with a fixed optical system, but with illumination from a light source at a different position in each image (see Fig. 1).
Web31. júl 2024 · Near-infrared reflectance (NIR) imaging is a noninvasive, noncontact, and rapid in vivo examination currently extensively available for ophthalmologists. Most … WebNIR spectroscopy is a method that makes use of the near-infrared region of the electromagnetic spectrum (from about 700 to 2500 nanometers). By measuring light scattered off of and through a sample, NIR reflectance spectra can be used to quickly determine a material’s properties without altering the sample.
