Metal Bolometers of Short Time of Response and High Sensitivity
Abstract
The requirements of Project Spruce are that a gunsight, sensitive to infra-red radiations from the target, be developed to indicate ' the presence of an airplane anywhere in an area of sky 30 degrees in diameter (or 30 degrees square) with such speed and resolving power that a fast approaching target can be located to 0.25 degree. Further, the requirement on range of the sight in use is that it detect a fighter airplane at night at distances greater than 1000 yards.
