Abstract
The settlement of archives of reference images useful for the diagnosis of the preservation state of paintings and restorer actions can be obtained using a spectrophotometric scanner capturing spectral images. This scanner is built arranging a spectrometer between the objective lens and a black and white digital matrix camera. The paper describes the working principles of the scanner, its technical properties, the fidelity of both the color acquisition and reproduction, and the spatial resolution. Practical works carried out using the scanner are shortly presented.| File | Dimensione | Formato | |
