Development of a Portable SLODAR Turbulence Profiler
We report on the development of a prototype portable monitor for profiling of the altitude and velocity of atmospheric optical turbulence. The instrument is based on the SLODAR Shack-Hartmann wave-front sensing technique, applied to a portable telescope and employing an electron-multiplication (EM) CCD camera as the wave-front sensor detector. Constructed for ESO by the astronomical instrumenta...
متن کاملA Portable Tillage Profiler for Measuring Subsoiling Disruption
A portable tillage profiler (PTP) was constructed using a laser distance sensor, a linear actuator, a portable PC, and a lightweight aluminum frame that can quickly and accurately measure aboveground and belowground soil disruption caused by tillage. A laboratory experiment was conducted that determined that soil color did not detrimentally affect the PTP, with expected vertical errors of 2.3 m...
متن کاملSlanted hole array beam profiler (SHArP)-a high-resolution portable beam profiler based on a linear aperture array.
We demonstrate a novel high-resolution portable beam profiler based on a slanted linear array of small apertures, termed a slanted hole array beam profiler (SHArP). The apertures are directly fabricated on a metal-coated CMOS imaging sensor. With a single linear scan, the aperture array can establish a virtual grid of sampling points for beam profiling. With our prototype, we demonstrate beam p...
متن کاملMicro-Profiler : A Fine-grained Application Profiler for ASIP Design
Current Application Specific Instruction set Processor (ASIP) design methodologies are mostly based on iterative architecture exploration that uses Architecture Description Languages (ADLs) and retargetable software development tools. However, for improved design efficiency, additional pre-architecture exploration tools are required to help narrow-down the huge design space and making coarsegra...
متن کاملBottom Stationed Ocean Profiler
The long term project goal is development and utilization of a bottom stationed autonomous ocean profiler for enhanced physical chemical and biological measurements in the coastal ocean.. The system is designed to allow bi-directional satellite communcation, user programmability, and data storage and transmission in near real-time. It is envisioned that deployments of large numbers of BSOP syst...
