Document Type and Number:
WIPO Patent Application WO2006089923
Kind Code:
A3
Abstract:
The invention concerns a device for countering and tracking a threat with optical delay device in the form of a homing-head missile, comprising a homing head adapted to receive an incident coherent light beam and in deflecting same to produce a transmitted beam. The invention is characterized in that the homing head comprises a biprism (10) dividing the transmitted beam into two sub-beams, the biprism (10) being associated with an optical delay device (130) introducing an optical path difference between the two sub-beams greater than the coherence length of the incident beam.
