Abstract : A quantitative method of determining the vulnerability of optical systems to high levels of thermal radiation energy from nuclear weapons is developed. The scale employed is the volume of space in which detonation of the weapon would disable the system by imaging of the fireball on the sensor. System parameters which are considered as affecting vulnerability are angle of aperture, optical gain, transmission of the optics, and the radiant exposure required to disable the sensor. Sample calculations are presented for a simple system. (Author)
