Abstract
The invention relates to a method and device for producing an optical link using light flashes. According to the invention, an arrangement (13) comprising a plurality of capacitors (C1 to C5) is provided in order to power a flash lamp (3) and the connection of said capacitors within the arrangement is controlled in a programmed manner such that the resulting capacitance thereof increases from one flash in the next.
Claims9
A method to produce an optical link, formed by a series of light flashes between a flashlamp and a device to locate a missile moving away from said locating device, each light flash being generated by an electrical discharge produced by a capacitive unit and applied to said flashlamp, the method comprising:
- configuring said capacitive unit to comprise a plurality of capacitors;
- and
- controlling said capacitors in a programmed manner in such a way that a resultant capacitance of said capacitors is used to generate the series of light flashes and increases from one light flash to the next.
A device to produce an optical link, formed by a series of light flashes between a flashlamp and a device to locate a missile moving away from said locating device, each light flash being generated by an electrical discharge produced by a capacitive unit and applied to said flashlamp, comprising:
- a capacitive unit comprising an arrangement of a plurality of circuit branches each comprising a capacitor and a controlled switch, said circuit branches being connected in parallel to one another between an anode and a cathode of said flashlamp;
- a high-voltage generator to supply voltage to said capacitors;
- and
- a control device to control said controlled switches to charge said capacitors using said high-voltage generator and to discharge said capacitors into said flashlamp so that an electrical discharge corresponding to a flash is larger than an electrical discharge corresponding to a preceding flash generated before the flash and smaller than a electrical discharge corresponding to a next flash generated after the flash.
