• Long-range adjustable-field background suppression sensor detects objects within a defined sensing field, while ignoring objects located beyond the sensing field cutoff • Two-turn, logarithmic adjustment of sensing field cutoff point from 0.2 m to 2 m (7.9 in to 6.6 ft); allows easy setting of cutoff point at long range • Rotating pointer indicates relative cutoff point setting • Easy push-bu...

H. S. Cho Korea Advanced Institute of Science and Technology Department of Mechanical Engineering 373-1 Kusongdong, Yusonggu Taejon, Korea E-mail: [email protected] Abstract. A specular surface reflects light only in the direction such that the angle of incidence equals the angle of reflection. Due to this characteristic, conventional approaches to obtain the shape of specular objects have ...

Infrared detector development and characterization at NASA Langley Research Center will be reviewed. These detectors were intended for ground, airborne, and space borne remote sensing applications. Discussion will be focused on recently developed single-element infrared detector and future development of near-infrared focal plane arrays (FPA). The FPA will be applied to next generation space-ba...

abstract the amount of needed fertilizer in agricultural soils depends to the type of crop. absence of enough fertilizer may cause in tensions in plants and consequently result in decrease in amount of product. according to the agricultural literature, soils containing total nitrogen amounts (n %) between 0.1-0.15 percent are considered as soils containing normal amounts of nitrogen. the values...

When a fiber Fabry-Perot is used in an ultra-sensitive strain detection system via a radio-frequency interrogation scheme, its frequency discrimination properties can be enhanced by reducing the linewidth of its resonance. This increases the signal-to-noise ratio, and thus suppresses the strain equivalent noise floor. We demonstrate this improvement in a long-distance high performance remote se...

This work investigates the use of deep fully convolutional neural networks (DFCNN) for pixel-wise scene labeling of Earth Observation images. Especially, we train a variant of the SegNet architecture on remote sensing data over an urban area and study different strategies for performing accurate semantic segmentation. Our contributions are the following: 1) we transfer efficiently a DFCNN from ...

We have created a new electronic musical instrument, referred to as the Termenova (Russian for “daughter of Theremin”) that combines a free-gesture capacitivesensing device with an optical sensing system that detects the reflection of a hand when it intersects a beam of an array of red lasers. The laser beams, which are made visible by a thin layer of theatrical mist, provide visual feedback an...
