Multispectral scanner optical system - Patent 4215273 (4960 words) |
 | Multispectral scanners for use with mechanical video systems are known and used, for example, in constructing pictures of ground terrain from a moving airplane. |
| Due to the varied transmission properties of optical devices in these wavelength regions, and the general dependency of detectors on the wavelength of the radiation being detected, the radiation may be separated within the optical system of the multispectral scanner and various wavelength portions of the radiation presented to appropriate detectors. |
| Thus, the reflecting mirror surface is elliptical in shape, with an elliptical aperture centered in the surface and having its major axis coincidental with that of the elliptical outer border of the surface. |
| Multispectral Imaging of Tablets in Blister Packaging (3183 words) |
| This study tests the hypothesis that a near-IR camera and multispectral imaging permits the identity and composition of large numbers of tablets to be determined simultaneously through blister packs to study stability. |
| Multispectral imaging offers a potential speed advantage of approximately 30 000 over HPLC when determining moisture and salicylic acid in single, packaged aspirin tablets. |
| Multispectral imaging of a field of tablets is approximately 1000 times faster than spectrometry of single tablets. |
