Abstract
Lidar systems and methods are presented herein. In one embodiment, a lidar system includes a laser operable to propagate ultrashort laser pulses to a target during a plurality of scanning periods. The lidar system also includes a streak tube imaging system operable to collect returns of the ultrashort laser pulses from the target during each scanning period, and to generate a two-dimensional image of the returns during each scanning period. The lidar system also includes a processor operable to generate a representation of the target based on the 2D images from the streak tube imaging system.

A laser ranging and detection (lidar) system, comprising:
- a laser operable to propagate ultrashort laser pulses to a target during a plurality of scanning periods;
- a streak tube imaging system operable to collect returns of the ultrashort laser pulses from the target during each scanning period, and to generate a two-dimensional (2D) image of the returns of the ultrashort laser pulses during each scanning period;
- and
- a processor operable to generate a representation of the target based on the 2D images from the streak tube imaging system.
A laser ranging and detection (lidar) method, comprising:
- propagating ultrashort laser pulses from a laser to a target during a plurality of scanning periods;
- collecting returns of the laser pulses from the target during each scanning period with a streak tube imaging system;
- generating a two-dimensional (2D) image of the returns of the ultrashort laser pulses during each scanning period;
- and
- generating a representation of the target based on the 2D images.
A laser ranging and detection (lidar) system, comprising:
- a laser operable to propagate laser pulses to a target;
- a streak tube imaging system operable to collect returns of the laser pulses from the target, to propagate electrons resulting from the returns to a phosphor screen using a pair of time varying waveforms, and to generate two-dimensional (2D) images of the returns based on the electrons;
- and
- a processor operable to generate a representation of the target based on the 2D images.
