Abstract:
The technology described applies an extended frequency range of over one octave to drive an acousto-optic deflector, thereby defying a design rule of thumb that limited bandwidth to just under one octave. A combination of extended frequency range and well-timed beam blanking reduces the proportion of a so-called chirp signal that is consumed by beam blanking. This increases the working, effective portion of the sweep signal.
