USE AND DESCRIPTION:
GARVAN is a single pulse electro-optical rangefinder designed for accurate and instant measuring ofthe distance between the operator and selected targets.
The rangefinder consists of a laser transmitter, laser receiver, power supply, control and signalprocessing electronics. A laser pulse is generated by the transmitter and directed towards the target.This laser pulse hits the target and is reflected back to the rangefinder. The time taken by the pulse totravel from the rangefinder to the target and back is measured and automatically converted to
GARVAN GV04 GARVAN GV04Yis an eye-safe version formeasuring the distance of ground targets. It isdesigned mainly for an installation in theobservation and recognition systems at themobile platforms.
is a version for measuringthe distance of aerial objects, where higherfrequency of measuring is requested andwhere are no safety requirements for the eyeprotection.
The control and evaluation system of this rangefinder is based on the digital signal processor (DSP)which enables the operator to optimize parameters for given application. The image of returned signalcan be send to the superior system for the further analyse.
