Pan & Tilt Hyperspectral Scanner
The earth tactive tripod allow you to scan a landscape or a static target since a synchronized tilting system will move the head. The target pointing is achieved with a software preview screen. Up to a couple of sensor can be lodged inside the same head (i.e. VNIR and SWIR) besides a standard camera used as pointing device. The power supply unit is a rack size external device (powered @28Vdc), and contains also the electronic controllers for the acquisition and control interface.
The P&T system is available for various wavelength ranges UV (200-400nm), VIS-S (400-700nm), VIS-NIR (400-1000nm), IR (900-1700nm), SWIR (1000-2500nm) and with different resolutions, depending on the chosen entrance slit dimension of the spectrograph, the chosen FOV and the target distance.

SPECTRAL SCANNER SOFTWARE
SpectralScanner© is a spectral imaging software that captures the spectral composition of each point of the sample using a line spectrometer. The Software controls a mechanical device which moves the optical system and captures a series of two-dimensional frames. By interpreting each of these as an array of spectra, point by point, the Software reconstructs an entire image on the screen line by line, making available all the spectral data which are displayed numerically and in graphical form on a chart, through Lab* coordinates and diagram and in the Munsell color space.
Reflectance, transmittance, absorbance
Many spectral imaging applications, like color measurement, require to determinate the absolute reflectance of the sample; Spectral Scanner calculates reflectance for every acquired pixel, evaluating the acquired signal ratio with a white reference sample. The mouse movement on the rendered image gives access to the spectral profiles of the selected pixels, instantly evaluates the colorimetric parameters and with one click lets you immediately save the data in various formats. Software filters allow narrow band analysis of the images. In the same way Spectral Scanner can render an image in transmittance mode for applications that require it.
Single wavelength selection
Spectral Scanner allows the selection of single bands with defined wavelengths and the visualization to screen of the rendered filtered images.
Data exportation
All the spectral reflectance data and colorimetric calculated values can be quickly exported for further elaborations with other mathematical applications and tools…
Advanced analysis tools
Spectral Scanner provides many tools that provides an intuitive user friendly path through the complexities of hyperspectral image exploration and the development of robust prediction models for either image feature classification or chemical component quantification. Moreover other application software are available by DV for advanced spectral analisys and color proof and simulation.
