Jones 2
Jones 2 :
A unit of detectivity, that is, the ability of an electronic device to detect radiant energy such as light waves or infrared radiation. In a 1959 paper, R. Clark Jones defined the "specific detectivity" of a device to be D* = [square root (Aw)]/N, where A is the area of the detector, w is the frequency bandwidth, and N is the power of the noise generated by the device. The quantity D* is measured in the complex unit cm Hz1/2/W, customarily called the "Jones." In modern equipment, detectivities are often quite large, in the range of 109 to 1012 Jones
