Abstract: We provide a wide-field time-resolved imaging apparatus using resonant drive. We also identify ideal configurations of electro-optic (EO) modulator crystals for wide-field imaging. These techniques enable compact and low-cost LIDAR imaging devices. Resonant drive affords modulation of various EO modulators at high voltage by means of resonant voltage enhancement. Further, it enables operation of imaging modulators at high frequencies which would otherwise not be possible with conventional pulsed drivers—this leads to improved LIDAR accuracy and dynamic range. Resonant drive uniquely enables Pockels cell LIDAR beyond normal flash mode by allowing for multiple pulses or multiple cycles of amplitude modulated illumination to be present simultaneously in a scene. This corresponds to illumination and modulation waveforms having a defined phase relationship where time-of-flight is encoded in the phase of the returning light waveform.
