【Abstract】 The physical mechanism is analyzed in which the optoelectronic sensitivity of the large area staring infrared (IR) focal plane arrays (FPAs) is improved. The filling factor of device is increased by using refractive convexes microlens array, and then the signal noise ratio characteristics improved. The influence of convex refractive microlens array to spatial resolution, detectivity D * , and nonuniformity of imaging device, is discussed.更多还原
