Optical trapping of single biological cells has become an established technique for controlling and studying fundamental behavior of single cells with their environment without having "many-body" interference. The development of such an instrument for optical diagnostics (including Raman and fluorescence for molecular diagnostics) via laser spectroscopy with either the "trapping" beam or second...

The purpose of this study is to design a portable virtual piano. By utilizing optical fiber gloves and the virtual piano software designed by this study, the user can play the piano anywhere at any time. This virtual piano consists of three major parts: finger tapping identification, hand movement and positioning identification, and MIDI software sound effect simulation. To play the virtual pia...

We describe a setup for addressable optical trapping in which a laser source is focused on a digital micromirror device and generates an optical trap in a microfluidic cell. In this paper, we report a proof-of-principle single beam/single micromirror/single three-dimensional trap arrangement that should serve as the basis for a multiple-trap instrument.

The Mercury Laser Altimeter (MLA), developed for the 2004 MESSENGER mission to Mercury, is designed to measure the planet's topography by laser ranging. A description of the MLA optical system and its measured optical performance during instrument-level and spacecraft-level integration and testing are presented.

The Lunar Orbiter Laser Altimeter (LOLA), developed for the 2009 Lunar Reconnaissance Orbiter (LRO) mission, is designed to measure the Moon's topography via laser ranging. A description of the LOLA optical system and its measured optical performance during instrument-level and spacecraft-level integration and testing are presented.

The technology of airborne remote sensing encompasses a broad class of airborne platforms and a wide suite of remote sensing instruments. Usable platforms range from airships (Hamley, 1994; Windischbauer and Hans, 1994), UAVs (Unmanned Airborne Vehicles, Miller et al., 1999; Petrie, 2001), and helicopters (Gade et al., 1998; Matthews et al., 1997; Schaepman et al., 1997), to standard and high-a...

Recent advances in Earth remote sensing imagers have being attempted with the launch of the first Fourier Transform Hyperspectral Imager placed on board of U.S. Department of Defence. From the analysis of alternative optical layouts for a stationary interferometer, we have developed a laboratory imaging interferometer operating in the Sagnac configuration. This instrument does not employ any mo...

Diffuse optical imaging is highly versatile and has a very broad range of applications in biology and medicine. It covers diffuse optical tomography, fluorescence diffuse optical tomography, bioluminescence, and a number of other new imaging methods. These methods of diffuse optical imaging have diversified instrument configurations but share the same core physical principle - light propagation...

The MEDUSA camera system is a high resolution earth observation instrument designed to operate from a long endurance UAV flying at stratospheric altitudes. Due to the technical constraints imposed on the instrument regarding mass, power and dimensions, the MEDUSA instrument shall experience large temperature variations induced by its varying environment in which it is operated. The induced phys...

Scanning Near-field Optical Microscopy (SNOM) is the leading instrument used to image optical fields on the nanometer scale. A metal-coating is typically applied to SNOM probes to define a subwavelength aperture and minimize optical leakage, but the presence of such coatings in the near field of the sample can often cause a substantial change in the sample emission properties. For the first tim...
