Hyperspectral Systems – Crime
Investigations
The hyperspectral camera has proven to be a valuable resource for crime
investigation. The areas which ultimately benefit from the detailed hyperspectral
examination are:
• Investigative guide for a given case. An example is the identification of a
typical vehicle in a hit-by case examination of paint and glass.
• Connect a crime scene or a victim to a suspect. This connection can be
provided through the examination of differrent types of physical evidences
such as hair, blood, semen, fingerprints.
• Confirmation or rejection of an alibi or statement of a suspect. In case of a
sudden fatal gunshot, the exam of the blood stains layout on the scene and
on the clothing may determine wether the victim strugged with the
aggressor or, conversely, was in quite reverse position. Questions , like
wether could the fatal shot have been fired by the victim or if the blood stains
were his work, can be answered by the assessment of physical elements.
• Suspect identification. The identification of a suspect is not only restricted to
this but is often determined through fingerprints or DNA testing.
• Induce a suspect to confess. In some cases, factual information of a
suspected provided by an examination of physical evidence, such as the
identification of the victim’s blood on clothing or fingerprints on weapons,
lead the person to confess involvement in a crime.
• Innocent exsemption. Can also be found physical evidences proving the
innocence of a person. This is often referred to exculpatory evidence. An
example of these evidence type could be the presence of DNA in the body
fluids.
OPTICAL ZOOM LENS FOR
CAMERAS
TMP-CATS2000 - IR 100X
Motorized Zoom Lens
Internal focusing system
The seven lenses of the first focus lens group are separated into groups of four
and three lenses which provides for rapid and accurate focussing on an object.
As the front lens does not rotate, a polarizing filter can be used.
Internal 2X Magnifier (Extender)
This lens provides for focal lenght from 1000 mm to 2000 mm which ca be
operated remotely.
Thus an image can be instantly expanded to 2X.
Day and Night Applications
The focal point remains almost constant under visible ray or 400nm to the near
infrared ray of 900nm (IR) and within the focus area of 10mm - 1000mm.
Across this range readjustment of focus should not be necessary.
Additionally, when using the 2X extender, lens back adjustment is not necessary
as the focus point of IR light and visible light are the same at the wide end.
Focussing will be required under IR light for focal lengths of 70 ~ 450mm.
For the ranges of 20 ~ 70mm and 450 ~ 2000mm focussing is not necessary.
