Solving real-life imaging challenges
using hyperspectral sensors
Introducing Specim
and their products
Specim (Spectral Imaging Ltd) is a global pioneer in hyperspectral imaging
products and the launch of their new ImSpector M-series imaging spectrographs
in response to market demand.
Specim manufactures of a variety of leading-edge, spectral-imaging components
that are optimised for use in harsh conditions, Specim's versatile products
can easily be deployed in all conditions: in laboratories, near production
lines, on-line, in the field and in the air. The Imspector series are
built with specifications to meet the most demanding requirements for
target detection with a wide swath width for efficiency in airborne uses.
The V10M Imspector has been designed with superior performance for airborne
and industrial quality control applications.
Employing unique spectrographic technologies, the ImSpector
spectrographs work as an add-on optical component that
changes an area-scan camera to a spectral line-imaging device. Adding
this functionality to a camera means that full, continuous spectral
information for each pixel in a line can be imaged with high-spatial
and high-spectral resolution. The Push-Broom technique used in the VM10
produces an area image from each capture which contains the spectral data
in a column for each spatial pixel on a line.
About the V10M
ImSpector
Specim has responded to market demand by launching this new, high-resolution
hyperspectral imaging spectrograph, the V10M
ImSpector, designed with the dimensions and exceptional
performance necessary for Unmanned Aerial Vehicles (UAV). Its use is not
limited solely to this type of application, however, and it can be deployed
to solve a variety of other challenging situations (see
below).
What the spectrograph delivers
The impressive performance from this light-weight spectrograph
is delivered in a format optimised to fit to small payload compartments
and gimbals. It delivers an increased spatial resolution for
push-broom hyperspectral imagers. Operating
in the VIS/NIR range of 380 to 1000 nm, the V10M provides
negligible sub-pixel distortions with an excellent 1300 pixels spatial
resolution. It does this with an uncompromised imaging speed of 100 frames-per-second.
(Higher frame rates are also possible with spectral binning).
Impressive optical light throughput, together with the most advanced and
sensitive detector technology available guarantees an excellent signal-to-noise
ratio.
All Specim imaging spectrographs are delivered in rugged, compact
packages (one of the smallest footprints in the market) and can
be used in a variety of situations and applications. Other hyperspectral
imagers are either bulky with good performance, or compact, with only
moderate performance. However, Specim has overcome these drawbacks and
offers clients in defence, security and industrial applications, an off-the-shelf
hyperspectral sensor that is innovative in its performance capabilities.

Examples of airborne deployments
for the ImSpector V10M Hyperspectral Sensor |
|
|
|
High spectral and spatial resolution provides the
ability to classify tree stands within a forest. Precise classification
of species by stand is possible. Long term forestry management and
record keeping is simplified when the mapped imagery is used in a
GIS program. Stress detection and forest inventory are two of the
common products of the AISA hyperspectral imagery. |
|
Rapid and accurate assessment of the damage helps
to maximize the cleanup efforts. Environmentally sensitive areas can
be targeted for protection and cleanup, and the long-term damage can
be minimized. Time sequence images of the oil can guide eff orts in
real-time by providing relative concentrations and accurate locations. |
What
is "push broom" technology?
All Specim hyperspectral products employ their proprietary push-broom
imaging technology.
Push-broom imaging provides highest performance and flexibility among
various hyperspectral imaging techniques and its major advantages are:
* Can be made to work in
all conditions.
* provides the highest imaging
speed and lowest heat load from illumination on the sample/target. (Because
push-broom technologies collect light much more efficiently from the sample/target
than any other hyperspectral technique.
