The LOFTI system is a triple field of view thermal imager designed
for surveillance and security applications where long standoff
ranges are necessary. At the heart of LOFTI is an Indium Antimonide
(InSb) detector optimized for high sensitivity and low noise in the
3mm
to 5mm
infrared band.
The system is turn-key and is offered as a camera or with an
ultra-high accuracy direct drive servo pan/tilt (pictured) or with a
more conventional gear driven pan-tilt. An integrated control system
and full-featured but simple to use GUI allows operation with
minimal training. Position and image setting presets permit set and
forget surveillance “tours” or real-time control of the camera via
joystick. The system is designed for installation into a pan-tilt
mount and is configured to allow several different control modes of
the mount motion.
Common image enhancement features are provided in the included GUI
or on the joystick. Polarity (white/hot – black/hot) control, color
map selection, date and time display, and AGC region of interest (ROI)
selection are all configurable. The imaging engine also allows for
both manual and automatic single point calibrations. The imager
also allows the user to select the method of AGC/ALC as well as
fully override these algorithms and use manual brightness and
contrast control.
The native control interface hardware utilizes an embedded computer
and communicates via an Ethernet link for control from any point
worldwide.
The LOFTI imager can be installed directly into any mount and may be
controlled through the interface software. The control link
provides mount capabilities such as jog, slew, preset, tour and scan
modes of operation. The system allows for up to 100 presets and 32
tours, with each tour having up to 32 preset points.
Equipped with heaters and internal fans with a water-tight
pressurized housing, the LOFTI is ready for nearly any environment.
Additional features include window heaters and a provision to
remotely update the software.
The LOFTI
has vehicle recognition capability to nearly 25km with personnel
identification (armed vs. unarmed) beyond 7km. Ideal for marine
applications, the LOFTI’s main telescope with its 1.5 meter
focal length allows type recognition of small craft beyond 20km with
a high degree of confidence.
