摘要：

We describe a new scheme for extending the bandwidth of IR detectors by the employment of a reticle that shifts the higher spatial-frequency content of the scene onto the lower-frequency region. Then all the spatial-frequency information can pass through the bandwidth of the detector system, so that a high-resolution image may be reconstructed from a series of pictures obtained with the reticle in a number of predetermined positions.
