Tomography is used to reconstruct 2-D images from 1-D range-resolved laser radar data. A doubled mode-locked Nd:YAG pulsed laser illuminates a conical object, and a receiver utilizing a streak camera resolves the reflected light in time.

As part of the early development for NASA's Mars Laser Communication Demonstration (now canceled), we exposed two InGaAs focal plane arrays (FPAs) to 22 krad(Si) dose at a rate of 4.6 rad(Si)/s using a 60 Co gamma-ray source. Both the SU320MS from Se

A high-speed imaging device based on a streak camera has been demonstrated, which provides multiple images from non-repeatable transient events of time scale >= 1 ns. It can be employed for pulsed laser beam diagnostics, measuring laser beam spatial

A high-speed imaging device has been built that is capable of recording several hundred images over a time span of 25 to 400 ns. The imager is based on a streak camera, which provides both spatial and temporal resolution. The system's current angular

This paper compares two detectors for visible laser radar: a 1-D detector that resolves a target in range and a 3-D detector that resolves a target in angle and range. For both, a short pulse laser illuminates the target. For both, the receiver is ba

We demonstrate a method of constructing two-dimensional projection images of objects using reflective tomography. The method consists of detecting reflected light from an object illuminated by short pulses (FWHM ≈ 100 ps) from a laser with high tim
