High Speed Ground Transportation

Ground-based and satellite observations of high-latitude auroral activity in the dusk sector of the auroral oval

On 7 December 2000, during 13:30–15:30 UT the MIRACLE all-sky camera at Ny Ålesund observed auroras at high-latitudes (MLAT ∼ 76) simultaneously when the Cluster spacecraft were skimming the magnetopause in the same MLT sector (at ∼ 16:00–18:00 MLT). The location of the auroras (near the ionospheric convection reversal boundary) and the clear correlation between their dynamics and IMF variation...

Ground-based Optical/Infrared Interferometry: High Resolution, High Precision Imaging

Over the past decade, optical interferometry has demonstrated that its combination of high resolution and high precision can make unique contributions to astrophysics. Interferometers have grown in aperture size, baseline length, number of apertures, and spectral resolution. At the same time, methods to circumvent the limitations of interferometry are being introduced. Further increases in sens...

High-speed AFM imaging.

Proteins are dynamic in nature and function at the single molecule level. To achieve a straightforward and in-depth understanding of their underlying functional mechanism, we need to directly observe protein molecules at work at high resolution, without the use of protein-attached markers. To realize such objectives, high-speed atomic force microscopy (HS-AFM) has been developed and recently it...

Compressive high-speed stereo imaging.

A compressive high-speed stereo imaging system is reported. The system is capable of reconstructing 3D videos at a frame rate 10 times higher than the sampling rate of the imaging sensors. An asymmetric configuration of stereo imaging system has been implemented by including a high-speed spatial modulator in one of the binocular views, and leaving the other view unchanged. We have developed a t...
