1650 L.A.M. images of the Mona LisaThe L.A.M. uses the 13 images of the MultiSpectral Camera. In addition to high-resolution images, this technique generates 1650 images calculated with mathematical algorithms based on the laws of light / matter interaction. These images make it possible to highlight underlying information that is invisible to the naked eye and sometimes invisible to Infrared. It is the essential complement to traditional scientific imaging methods: X-ray, Infrared 1700/2500 nm, UV fluorescence etc.

Difference between diffraction and refractionwith examples

Reflection: This is when a wave hits a surface (e.g light hitting a mirror) and is bounced back. Remember that in reflection the angle of incidence (this is the angle that the initial wave makes from the normal), is the same as the angle of reflection (the angle that the reflected wave makes from the normal).

The spectra measured by the multispectral camera can be reprocessed to eliminate the influence of an old yellowed varnish. A database of artificially aged varnishes allows an algorithm to simulate and calculate colors without the varnish. The result does not give the original colors but the colors underlying the varnish, which have deteriorated over time.

reflection, refraction,diffraction andinterference

Diffraction: Waves spread out as they enter an aperture (gap). The most amount of diffraction happens when the wavelength is a similar size to the gap.

The spectra measured by the multispectral camera make it possible to identify certain pigments. It is a complement to traditional studies (XRF, Micro Raman, etc.). Software searches the pigment database for combinations of spectra that approximate the spectra measured on the board. The identification of pigments is an essential contribution in the authentication protocol of an artwork.

These are all properties of waves and their definitions are useful to remember for exams. It can also be helpful to draw diagrams of each to help you to remember the difference. On the diagram it is useful to mark on a line for 'normal', this is a straight line that is perpendicular (makes a 90 degree angle) with a surface.

Refraction: When light travels from air into another material (such as glass) at any angle other than normal (perpendicular), it slows down. As it slows down it changes direction, meaning that the angle that it is travelling at changes - the angle becomes closer to the normal. (a picture would help to explain this)

The multispectral camera provides high resolution images. The definition (DPI) depends on the dimensions of the work to be digitized.Mona Lisa scan in progress List of images produced :
