Dual-beam laser deflection sensor

Review of Scientific Instruments, 1985
A compact, dual-beam laser deflection system was built, mainly from commercially available parts. While the detector and electronics yielded noise levels at the theoretical level for the detector, pointing instability of the laser led to an increase in noise by a factor of about 103.

Inexpensive Dual Beam Turbidimeter

SEPM Journal of Sedimentary Research, 1973
ABSTRACT This dual beam turbidimeter can be made for under $1000. The light source is a 2 milliwatt helium neon laser. Use of a laser eliminates the need for collimating optics. The light detector is a photomultiplier tube, thus permitting the measurement of low particle concentrations. The reproducibility of the transmittance is 1%.

Cygnus Dual Beam Radiography Source

2005 IEEE Pulsed Power Conference, 2005
The subcritical experiment (SCE) program was initiated after the 1992 moratorium on underground nuclear testing in support of stockpile stewardship. The dynamic material properties of plutonium are a major topic of exploration for the SCE program.

XEBIC at the Dual Beam

Microelectronics Reliability, 2013
Abstract After its golden age during the decades of the development of Silicon IC technology, nowadays Electron Beam Induced Current (EBIC) technique comes back to importance mostly on photonic and high speed electron devices based on compound semiconductors. A new approach for recording a fast EBIC embedded in a Dual Beam system is presented.

Facility for simultaneous dual-beam ion implantation

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2005
Abstract The dual implantation chamber (DIC) at Rossendorf Center for Application of Ion Beams in Materials Research allows materials to be implanted using two ion beams simultaneously. This facility is located at the 45 o cross point of two beam lines, one from a single-ended HVEE 500 kV ion implanter and the other from a HVEE 3 MV Tandetron ...

Viscously coupled dual beam accelerometer

The Journal of the Acoustical Society of America, 1993
A viscously coupled dual beam accelerometer. An accelerometer (60) includes a first proof mass (32') and a second proof mass (42'), which are respectively connected by flexures (36' and 46') to a first base (34') and a second base (44'). The first and second bases are clamped between a top enclosure (62) and a bottom enclosure (64), between which is ...

Dual beam modulated magneto-optical measurement setup

Review of Scientific Instruments, 2019
A dual beam magneto-optical setup employing a dual axis photoelastic modulator (PEM) and an intensity-stabilized laser was designed and constructed. The beam transmitted through or reflected of the sample is split by a Wollaston prism into two orthogonal high-quality linearly polarized beams.

Spatial phase-shift dual-beam speckle interferometry

Applied Optics, 2018
The spatial phase-shift technique has been successfully applied to an out-of-plane speckle interferometry system. Its application to a pure in-plane sensitive system has not been reported yet. This paper presents a novel optical configuration that enables the application of the spatial phase-shift technique to pure in-plane sensitive dual-beam speckle ...

Dual beam mode-locked laser

Optical Society of America Annual Meeting, 1991
A natural extension of mode-locked laser technology is the realization of spatially extended arrays of synchronized mode-locked lasers. Such lasers have a potential for producing arrays of ultrashort optical pulses that are structured in space and time.

Dual-beam interferometer for optical difference measurements

Applied Optics, 1984
A dual-beam interferometer system is presented for performing reflectivity and absorption measurements in the 10–400-cm−1 far-infrared region. This system is designed for cryogenic applications intended for solid state spectroscopy. It consists of two coupled interferometers for optical difference measurements.
