FDVI Mark IV 3000
Description
The new M,F& A Mark IV All Fiber Doppler Velocity Interferometer Systems offer enhanced capabilities in the measurement and recording of instantaneous velocity versus time histories. Two versions of the Mark IV Systems are now available. The original Mark IV has been in use all over the world and gives excellent results provided that the target surface of interest is reasonably reflective. In the latest version of the Mark IV we have up-graded to a new ultra-narrow linewidth laser for enhanced velocity resolution. These systems also incorporate the latest developments, such as a new Nickel Metal Hydride power and charging system, new front panel arrangement including a “Balance” knob to easily equalize the “sin” and “cos” signal amplitudes and a digital battery voltage monitor. The new systems are built in a 1U Rack Mount chassis and can be easily up-graded to the Mark IV-3000 by the addition of the EDFA at a later date if desired. The Mark IV-3000 features an entirely new system architecture based on the same ultra-narrow linewidth seed laser but this version incorporates an EDFA with +30 dB gain to boost the relatively weak return light from marginal target surfaces to levels that give high signal to noise ratios at the detection end. This boost in the reflected return light is the equivalent of putting 3000 mW of laser power on the target.
