The system mainly consists of two collecting chains; one laser range finder for land (topographic)
and a camera collecting images.

The laser range finders emits pulses and measure the time distance from output pulse to return pulse
in order to calculate the distance to target. The laser range finders consists of a laser,
photo detectors and receiver electronics, rotating mirror, reception telescope and control
computers.
The pulsed laser responses are received by a telescope and photo detectors converting them to electrical
signals. The signals are sampled using digitizers and stored together with navigational data
and scanner positions in order to enable post processed high precision positions of
land. The data is also processed during flight for realtime presentation and monitoring of
survey progress.
The Digital Cameras takes images in a rate that it covers the ground with some overlap. Each image covers
the width of the flightline.

The Dragon Eye System consists mainly of one unit
- Sensor System (460x400x250mm, 25kg)
The following parts are also included in the Dragon Eye System
- Operator Console Laptop
(330x272x31mm, 3kg)
- Pilot Monitor (255x170x60mm,
2kg)
- System Cabling (5kg)
- Aircraft Installation Kit (700x540x10mm, 4kg)

The Dragon Eye System Sensor is both the heart and the brain of the measurement system
and controls and supervise the following vital parts of the system:
- Scanner for positioning the
shots on the ground/surface and compensate for roll
deviations.
- Laser
- Receiver that makes it
possible to collect topographic data at up to 300kHz
- Digital cameras that stores high quality timestamped images.
