Abstract
The concept of the zoom FFT (a more efficient algorithm which allows zooming in on a narrow segment of the spectrum while preserving its frequency content) is extended to the two-dimensional case. The technique is further expanded to allow zooms over a specified segment within both the time and the frequency domains. Comparisons are also made as to the computational efficiency of this technique compared to the conventional two-dimensional FFT algorithms.
