Abstract:
An imaging system for registering electrical images at a plurality of selectable resolutions, comprising:an optical system; and,a sensing system further comprising a number of photosensor arrays wherein said number is an integer N greater than or equal to 2, said photosensor arrays having optical line spacings OLS(K+1:K) in reference to a leading photosensor array K and with respect to a lagging photosensor array K+1, for K equal to an integer from 1 to N-1, each of said number of N photosensor arrays further including a corresponding number of N transfer gate receiving means, so that, each of said N photosensor arrays is capable of being independently triggered to convert optical signals into electrical signals in response to a corresponding one of a plurality of transfer gate signals, TG.sub.i (t), for i equal to an integer from 1 to N, wherein each one of said transfer gate signals has a periodicity T and angular frequency .omega., said transfer gate signals being of the general form TG.sub.i (t)=TG.sub.i (.omega.(t-.tau..sub.i)).
