Broad-band high-resolution (4pixel/mm) acquisition with actuated planar scanner

This is a digital IR B/W acquisition performed with the Art-Test unique > Vis IR actuated planar scanner, with sensitivity till 1700 nm, and a radiation source with continuous emission spectrum, and rich emission in the long wavelength range.

The acquisition is performed with a standardized procedure, implying the device prior lab calibration, an on-site calibration, stable set-up, sensitivity, filter system and radiation source, whose characteristics are mentioned in the technical report. This will be provided together with the acquired and processed data.

Images will be provided with 8 and 16 bit resolution, with high spatial resolution, in raw and tiff format (or similar, as agreed upon) on a CD or DVD.

If the acquisition consists of more than one image, a mosaic of the various images will be performed and provided.
Prints of the images will be provided upon request*.
An IR-false colour image may also be provided upon request*.

Average acquisition time: 2h/mq.

CCD Multispectral acqusition

This is a digital IR B/W acquisition performed with a scientific cooled digital CCD camera, with sensitivity till 1100 nm, a set of 8 narrow-band (40-50 nm) interferential filters, in the 750-1100 nm range. The radiation source has a continuous emission spectrum, and rich emission in the long wavelength range.

The acquisition is performed with a standardized procedure, implying the device prior lab calibration, an on-site calibration, stable set-up, sensitivity, filter system and radiation source, whose characteristics are mentioned in the technical report. This will be provided together with the acquired and processed data.

Data processing will be performed in order to enhance data fruition, e.g. by differentiating and spatially locating the various homogeneous areas, and comparing them with data in our database, in order to identify the different materials. This method is specifically designed for this.
