Claim One:
1. A focal plane imaging array having a dynamic range, comprising: a detector with a large pixel array having a plurality of large pixels, each of said large pixels having a large pixel area and a large pixel signal contact, to create a first signal that travels to said large pixel signal contact, and a small pixel array having a plurality of small pixels, each of said small pixels having a small pixel area and a small pixel signal contact, to create a second signal that travels to said small pixel signal contacts, wherein said plurality of small pixels is larger than said plurality of large pixels, wherein said large pixel array and said small pixel array are aligned and vertically stacked on a monolithic semiconductor substrate; a readout integrated circuit operably interconnected to said large pixel signal contacts and said small pixel signal contacts; and a clock operably connected to said large pixel signal contacts and said small pixel signal contacts to read said first signals at a first clock rate having a first integration time and a first reset time, and to read said second signals at a second clock rate having a second integration time and a second reset time; wherein said first clock rate is faster than said second clock rate; whereby reading of said first signals at said first clock rate, and said second signals at said second clock rate, extends said dynamic range.
