dc.description.abstractIn this work, we demonstrate a simple square-wave electrical modulation scheme for imaging with laser feedback interferometry (LFI). Distinct advantages of this scheme include (a) the straightforward creation of the modulating signal, even for high-current lasers, and (b) its natural suitability for lock-in detection. We compare this simple scheme against two established imaging modalities for LFI: mechanical modulation using an optical chopper and the swept-frequency feedback interferometry approach. The proposed scheme lends itself to high frequency modulation which paves the way for high frame-rate LFI imaging with no motion artefacts using off-the-shelf equipment.
