Figure 1. Photograph of the imaging spectrometer used for the second quarter effort. The
small size and cost of this device, fabricated by AdvR, makes development of a
commercial instrument based on this technology economically viable.
To access the information recorded by the imaging spectrometer, a frame-grabber
is required, which is installed in a personal computer. (Future generation devices may be
able to use a microprocessor.) With the frame-grabber, the images are transformed into
digital data that can be analyzed using numerical algorithms. A typical example of the
spectral data from the imaging spectrometer shown in Figure 1 is shown in Figure 2. The
data shown in Figure 2 is from an airborne application.
As shown in Figure 2, the raw data from the imaging spectrometer does not look
like an image of the object. The important thing to note from the data is that the spectral
response from each imaged is recorded. This spectral information is what is used to
differentiate the objects of interest from the background. Because the imaging
spectrometer provides 320 spectral channels, there is sufficient data to differentiate
between similar objects. For example, hyperspectral imaging spectrometers can
differentiate between tree species from satellite platforms.[1]3
