Frequency-to-time mapping (FTM) is a technique that is becoming popular for applications like spectroscopy, imaging, and the generation of arbitrary waveforms. FTM provides a convenient way to detect the optical power spectrum of the signal, but it is subject to the far field condition, which sets a limit on the dispersion and complexity of the signal. This limit reduces both the bandwidth and the fidelity of the signal that can be generated with these systems.

Researchers at Purdue University have developed a new technique, virtual-time-lens-assisted frequency-to-time-mapping (VFTM), which circumvents the far-field limitation for generating arbitrary waveforms. This technique could be used in chirped radar, high-speed wireless covert system, or RF sensing systems. It improves bandwidth by nearly an order of magnitude over previous systems, enabling it to be fast enough to achieve space-time focusing.

Advantages:
-Radically improved bandwidth
-Removes far-field limitation

Potential Applications:
-Electronics industry
-Chirped radar
-High-speed wireless covert systems
-RF sensing
