Bridging research with innovative products: a compact hyperspectral camera for investigating artworks: a feasibility study

Spectral imaging and spectral LIDAR systems: moving toward compact nanophotonics-based sensing

“…Recently, studies on compact hyperspectral camera from SPECIM for imaging of art work have been conducted [43,56]. In the study by Picollo et al [43], the new commercial hyperspectral camera working from 400 to 1000 nm has been used for inspection of art works.…”

Hyper-Spectral Imaging Technique in the Cultural Heritage Field: New Possible Scenarios

“…Furthermore, this system works like a reflex camera with an interactive and touch display in the back of the camera that allow controlling the entire set of data acquisition and processing operations (Figure 3). Moreover, it has been designed as a mobile, hand-held and stand-alone HSI camera for applications in different kinds of environments [31,58]. The integrated color camera supports the spectral camera usage by allowing the visualization of the scene and adjustment of the manual focus of the spectral camera.…”

“…Typically, these devices have mainly been designed to work on panel paintings, at a macroscopic scale and at a short distance from the target, covering areas of limited sizes that range from tens of square centimeters to few square meters. However, recent publications have demonstrated that a remote sensing-like approach could successfully be used to extend HSI applications to larger surfaces, such as frescoes and mural paintings [29][30][31][32]. Such studies report on the use of readapted avionic HSI sensors, or in other cases compact HSI cameras featuring very flexible optical features that were used for the inspection of outdoors targets at distances of several meters.…”

A New Compact VNIR Hyperspectral Imaging System for Non-Invasive Analysis in the FineArt and Architecture Fields

“…Subsequently, it was tested the usability of the Specim IQ camera for remote acquisitions on outdoor large size painted surfaces, hardly to reach because of their location, such as one of the painted lunette in the Sant'Antonino cloister of the San Marco Museum in Florence [6]. This cloister has been decorated with mural paintings by different artists over three centuries starting from the 15 th century.…”

“…The camera operates in the 400-1000nm spectral range and can be mounted on a tripod. It can operate from short-distance (tens of cm) to long distances (tens of meters) with different spatial resolutions [6]. These technical features furtherly extend the possibility of applications of HSI to new typologies of artworks, both indoor and outdoor, from large-size wall paintings, ceilings, decorative elements and inscriptions to façade of historical buildings and monuments, as well as inspection small details of interest selected on the surface of almost flat objects.…”
