Spectra Insight™ Software  
HyperSpectral Imaging; spectrometer

Hyperspectral Cube. The Cube is like a 3D x-ray, where all regions within the cube are viewable by rotating, panning, zooming, and slicing through the cube.

 

The x and y axis define the plane of the Hyperspectral image, and the Z axis is wavelength. Each colored column along the z-axis represents a viewable object.  For the visible region, colors are actual. In this case we see most flora reflecting red but not all reflect violet or ultraviolet.

Spectral Insight acquires and processes spectral data in near-real time from virtual any imaging spectrometer. Spectral data can be imported from 3rd party sources for analysis. Image size/resolution and spectral range/resolution are limited only by the imaging spectrometer.

Spectral Insight utilizes fast voxel processing to display thousands of spectral images as a movie or as a rotating 3D volume in real-time. Each planar image or 3D volume are assigned unique color palettes associated with a wavelength or set of wavelengths. For example, wavelengths in the blue region can be given a blue scale pallet ranging from 0-255 while images in the infrared wavelength region are given a grey scale palette ranging from 0-255.

 

Within the 3D volume, virtual images are stacked and displayable in three different planes xy, xz, and yz and displayed as a movie. There is a full spectrum at each xy position, a set of y-coordinates as a function of x-position and wavelength, and a full set of x-coordinates as a function of y-position and wavelength. A spectrometer with 2048 wavebands scanning across 1000 xy-points provides 2048+1000+1000 (4048) unique images to display and analyze for unique characteristics of each measurement sample. Each image plane is color coded to enhance important aspects of the measurement sample.

Each pixel, region, spectral image, and 3D volume can be analyzed for anomalies and/or compared with native or 3rd party spectral databases.

Partial Feature Summary:

  • Spectral data acquisition over user selectable areas and resolutions.

  • Selectable wavelength ranges and bandwidths (see spectrometer options).

  • Thousands of spectral bands displayed as images or a movie.

  • Unique color palettes for ultra-violet, visible, and infrared wavelengths.

  • Search for anomalies.

  • Search local or online spectral database for signature matching.

  • Analyze entire images, selectable regions, or individual pixels in seconds.

  • Display volumetric, 3D Surface, 2D Image, cross-sections, and pixel spectral data.

  • Spectral normalization using industry standards such as Spectralon White or any desired spectral data.

  • Import 3rd party spectral data for analysis.

New in Version 1.2 !

  • Parallel Processing now allows real-time visualization and statistical analysis of any region within a Hyperspectral 3D Cube containing thousands of images, each at a different wavelength.

  • Using parallel processing, the entire Hyperspectral 3D Image can be scanned for a spectral match of any desired substance within one second using an Intel i7 4-Core 8-Thread processor. For the Hyperspectral image in Figure 1A, that’s 60,000 spectral searches/matches in one second. Much higher speeds can be achieved with higher end computers and/or additional processers without any change to the Spectra Insight software.

  • Pseudo RGB color images can now be simulated across any spectral range.

  • Multiple wavelength planes can be analyzed individually or simultaneously.

 

Flexibility

Color of cross sections is average of that particular color band. Grey cross section is the near infrared band (780 to 1100 nm).
