Osvětlovací technika moderních vozidel a měření dohlednosti na koncová světla / The Lighting Equipment Used in Modern Vehicles and the Measurement of the Range of Visibility of the Rear Lights

Belák, Michal Unknown Date (has links)
This work is about lighting equipment of modern vehicles, its historical development, present condition and possibilities of its further progress and measuring of the range of visibility of the rear lights. First part is aimed at lighting equipment used in modern vehicles as a whole. It describes sources of light, their principle, construction, advantages and disadvantages. Next it deals with searchlights and other lighting devices, their gradual development, construction and modern solutions which are used in them, and also their future development. Second part of the work is aimed at characterization of ways of measuring the range of visibility used in practice, their possible application to measuring of the range of visibility of the rear lights and on proposal of presentive methodics for this measurement. Realization and interpretation of practical measurement by this methodics is included.

A comparison of in-situ measurements and satellite remote sensing of underwater visibility

Museler, Erica A. 03 1900 (has links)
Approved for public release; distribution is unlimited. / SeaWiFS data converted to optical properties of the ocean in the form of vertical and horizontal underwater visibility products are compared to in-water diver and optical instrument measurements during the Model Diver Visibility (MoDiV) experiment. Results were collected from 19 to 21 August in the Mississippi Bight region of the United States. The SeaWiFS satellite data was processed with the Automated Processing System (APS), developed by the Naval Research Laboratory (Code 7333). APS converted radiance values into specific parameters studied: the beam attenuation coefficient, the diffuse attenuation coefficient, vertical visibility and horizontal visibility. These values were compared to the AC-9instrument, a-Beta instrument, Secchi disk and the observed visibilities from the divers. The results indicated that the beam attenuation coefficient and the diffuse attenuation coefficient are underestimated as compared to the in-situ measurements. These values then overestimate the vertical and horizontal visibility as compared to the Secchi disk and diver sightings. The visibility products from SeaWiFS should be used on an experimental basis for Naval Operational Planning. It is recommended that the use of in-water diver reports noting variability of SeaWiFS visibility product estimates are necessary for validation and offers feedback to the research and development field for algorithm improvement. / Lieutenant, United States Navy
