Theodolite With CCD Camera for Safe Measurement of Laser-Beam Pointing
The simple addition of a charge-coupled-device (CCD) camera to a theodolite makes it safe to measure the pointing direction of a laser beam. The present state of the art requires this to be a custom addition because theodolites are manufactured without CCD cameras as standard or...

Software Automates Processing of SAR Image Data
The Automated SAR Image Processor (ASIP) computer program increases the efficiency of production of scientifically useful imagery from raw synthetic-aperture-radar (SAR) image data. In the absence of ASIP, the processing of SAR data is a labor-intensive task, often involving supporting personnel, that...

Automated Detection of Streaks in Rocket-Engine Plumes
A high-speed observer (HSO) system comprising a high-frame-rate digital video camera and a high-speed computer that processes the camera output has been developed for use in monitoring the exhaust plume of the space shuttle main engine (SSME) during tests. The HSO system is designed to analyze...
Briefs: Semiconductors & ICs
Active-pixel integrated-circuit image sensors that can be programmed in real-time to effect artificial reconfigurable vision on demand have been developed and demonstrated. In...

High-Performance Processor of Hyperspectral Images
The Remote Sensing Hyperspectral Engine (RSHE) is a special-purpose, portable computer that performs high-performance processing of hyperspectral image data collected by a remote-sensing optoelectronic apparatus. Typically, the remote-sensing apparatus is airborne or spaceborne, the images are of...
Briefs: Photonics/Optics
An optoelectronic system discussed herein measures the state of alignment (SOA) of an object under test in four of its six degrees of freedom (DOFs). This system was originally...
