ABSTRACT:
A safety system and technique for multi-aperture optical systems such as TOW missile system that protects against the inadvertent activation of system function and warning the user that the system function is not ready for activation. The electrical trigger for the TOW missile system sends a signal to the firing circuits to launch a TOW missile. A micro-switch is mounted on the barrel of the near infrared (IR) tracker optical system fore optics, activated by the presence of a lens cap. A light group including a green and red light is included in the visible optical system of the TOW missile system. If the lens cap is off, then a green light is visible and firing circuits may be activated by a trigger. If the lens cap was inadvertently left on near IR tracking fore optics then a red light is visible and no voltage flows to the firing circuit when the trigger is depressed.
