Abstract
An improved ignition safety device (ISD) employs one or more optical switches to accomplish a SAFE-ARM function for a laser initiated ordnance system (LIOS). At least one optical switch along with appropriate control and status monitoring provide an optical SAFE-ARM function and optionally a distribution function. An optical switch performing the SAFE-ARM function diverts a laser signal to a heat sink assembly when in a SAFED position and switches to the LIOS when in an ARMED position. When in the SAFED position, the LOSAD provides an optical block in the laser energy path between a laser firing unit and the LIOS to prevent inadvertent ordnance operation. An optical switch performing the distribution function has two or more switch positions that direct a received laser signal to two or more laser initiated devices.
