Survey camera

The principle of optical triangulation has been known since the time of the early Greeks, and indeed optical triangulation has been used for hundreds of years in applications such as surveying, camera auto-focus and even smart-bombs. With the advent of low-cost, compact electro-optic components such as lateral-effect photodetectors, diode lasers and micro-optics, laser-based triangulation sensors can now be employed for applications that were, heretofore, considered uninspectable. 

Video surveying Cameras are lowered down the well, which allows for a visual inspection of the well. In particular, the integrity of the borehole, casing, concrete and tubing can be checked. The fractures in the receptor zone into which the concentrate is injected can also assessed... 

Abstract. A JHKK survey camera based on a 1040 X 1040 PtSi Charge Sweq> Device has been constructed in a joint programme of the University of Tokyo, the National Astronomical Observatory of Japan and the South African Astronomical Observatory. We describe its design, construction and initial testing. 

Our current instrumentation projects include (i) KCstm, a dedicated 2/on survey camera based on a 256x256 HgCdTe NICMOS 3 detector from Rockwell International (ii) Gemini, a general purpose l-5 mi imaging system... 

ACBAR is a bolometric camera array mounted on the VIPER 2 meter diameter telescope at the South Pole. It operates at several frequencies on both sides of the peak of the spectrum of the CMB, and thus can be used to make a sensitive test for the Sunyaev-Zeldovich effect. However, the data released to date are only at one frequency. ACBAR was able to measure the CMB angular power spectrum up to l > 2000 (Kuo et al., 2002), but the size of the surveyed regions was so small that ACBAR s l resolution was too limited to provide much information about tvk. ACBAR was able with its high observing frequency to show that the excess at l > 2000 seen by CBI (Mason et al., 2003) is not a primary CMB anisotropy. It could be due to point sources, or it could... 

His raised vobe merged into a howl of feedback. As he sat back the hal burst into conmotion Many of the people in the chairs came to their feet, applauding and shouting approval As the cameras flashed and journalists shouted questions, Scarsdale sat centre stage and surveyed his work. For a moment he looked right at me. His eyes burned wkh fervour. And triunph, I realized. 

The temperature of the plate can be measured by IR camera, and the tenq)erature evolution during product application can be followed when taking into account the emissivity change due to product deposit. An ultra-rapid camera can survey the drop impact at the same time. The amount of product transferred can be determined by weight difference of the small metal plate before and after the application. 

More efficient techniques for underwater search need to be developed. These techniques should make use of integrated suites of instruments, including visual (video cameras and laser line scanning equipment) and other sensors (e.g., magnetometer arrays) to support the search and reduce the need for divers. Boat-towed platforms rather than free swimming underwater vehicles would appear to be preferable for integrated underwater survey systems. 

There is now a considerable number of SR instruments which have been or are being used for protein crystallography at various SR sources around the world (table 5.5 documents the existing ones). In this section a survey is made of the various instruments. An extensive discussion of mirror-monochromator cameras used for small angle diffraction at DESY, NINA, SPEAR, VEPP-3 and DORIS has been given by Rosenbaum and Holmes (1980). 

Vent fields have been discovered in numerous ways, but surveys of the overlying water column and camera tows are the most common systematic approaches employed today. The venting of hot/warm water often forms a plume with unique temperature, salinity, reduced light transmittance, and other specific chemical signals several hundred meters above the ridge. The presence of such a plume is often the first indication that a given section of ridge is hydrothermally active. Cameras, or other... 

The other chapters cover the synthesis and chemistry of the more common heterocycles in order of increasing ring size. The publication of the Second Edition of Comprehensive Heterocyclic Chemistry has provided a welcome updating of the 1984 reviews and we intend that these annual surveys will eontinue to provide a source of information on further important advances. Because of the ever increasing volume of literature to be surveyed we have asked our authors to provide selective and critical reviews of the more significant papers when space does not allow comprehensive coverage. We appreciate their cooperation in this, and particularly for providing camera-ready scripts in a standardised format. The reference system used in the chapters is based on journal codes as described in Comprehensive Heterocyclic Chemistry. 

A survey of different cameras used for small-angle analysis has been given by Pedersen [69] which provides a practically complete overview of all systems used up to now for SANS and SAXS. Here we shall focus on devices used for SAXS-measurements. In particular, an extended discussion of the Kratky-cam-era [70,71] will be given because this device allows very accurate SAXS-measurements using an ordinary X-ray generator. Most of the experimental investigations on polymeric latexes have been conducted using this type of SAXS-cam-era. Since this device works in slit collimation, the correction of the data will be discussed in detail. 

A new development in the use of GPS is the deployment of multiple antenna arrays for the purpose of determining the attitude of a platform. Although initially the work was confined to military applications, currently proposed uses include the spatial orientation of survey vessels, photogrammetric cameras, and remote sensing platforms. The latter would eliminate the need for the provision of ground control which is required at present for absolute orientation .

The measurement values obtained from a geodetic survey have errors. Therefore, if it is possible to estimate the approximate value for the measurement value, then it will be possible to adopt the approximate value instead of the measurement value in the theory of simultaneous adjustment. The approximate values for the eight unknowns tio,vo,c,ai, - in Eq. (6) can be estimated by the equipment such as a camera, video monitor or A/D converter. Therefore, we assume the correction value for each of the unknowns, the difference between the most probable value and the approximate value, to be the measurement value. The least squares equation for the calibration in the 2-D field can be written as follows ...
