Patent ID: 8860586

Claim:
A test arrangement for a laser threats identifying system of an aircraft, comprising: an optical detector, adapted to pick up threat light beams impinging on the aircraft from a plurality of surrounding space sectors; a threat warning unit, adapted to receive a plurality of actual optical signals indicative of at least one of said threat beams through a plurality of optical channels related to respective beam incidence directions, and arranged for comparing said actual signals with a predetermined library of reference optical signals representing known threats; a light emitting device arranged for selectively generating a plurality of predetermined optical signals for simulating virtual threats; a plurality of optical guides for said simulation signals, directly coupled to said light emitting device and adapted to be connected to said plurality of optical channels for selectively stimulating the threat warning unit; one light emitting source and a switching circuit for selectively routing the simulation signals generated by said source into one of said plurality of optical guides; and a photo-detecting device selectively arranged at the output of said optical guides, adapted to intercept the generated optical simulation signals arranged for providing feedback signals to a driving circuit for providing power to the light emitting device and controlling the switching circuit.
