Here is a 2 minute 5.02MB Quicktime .mov file demonstrating the use of the Near Infrared spectroscopy (NIR) instrument that has been developed in the SurveNIR project. Sound is not necessary although there are some background noises audible in the file.
The first shots show the illumination of the instrument measuring head without a sample being in place. Dr Lichtblau (Zentrum für Bucherhaltung GmbH) is then shown setting up the computer and database. Further shots show Dr Lichtblau and Tanja Trafela (University of Ljubljana) using the instrument to assess the condition of a Paix Stockholm, Peace Poster, Paris, 1958, Picasso (Victoria and Albert Museum E.1848-2004). The poster is placed on to the NIR table and a small hand held pressure plate ensures positive and reproducible contact with the instrument measuring spot. Measurement is activated by a small foot operated switch that is not visible in the video. Several measurements are taken in different areas of the poster. Through a series of pre-measured calibration data sets, it is possible to provide quantitative measurements of the condition of the paper used for the poster and other paper items in collections.
