Abstract: An ordnance fuse apparatus (100) is described that uses electrical and mechanical, and optical devices. The ordnance fuse apparatus includes a controller (150) to control an optical switch (120) and a laser (111) to detonate an explosive charge (140) of the ordnance. Other embodiments include an accelerometer (122) and/or spin detector (123) for detecting that the ordnance has been fired and an optical detector (114) for detecting the proper operation of the laser (111) and a position sensor for detecting correct positioning of the optical switch (120). Another embodiment includes a microlens (130) to focus the laser optical signal onto the ignitor. In yet other embodiments, the explosive charge (140) is detonated either by ignition of an ignitor or by a shock wave from the ignitor. The resulting ordnance fuse apparatus (100) has significantly reduced size and improved performance and safety.
