There are two popular approaches to the design of a polarimetric radiometer: using either coherent or incoherent detection. Coherent detection implies that a direct cross-correlation is performed of the vertical and horizontal components of the incident electrical field. Incoherent detection derives the third and fourth Stokes parameters indirectly, by differencing the brightness temperatures d...

I am developing two related instruments for use in the Atmospheric Radiation Measurement (ARM) p,rogram; both use an automated rotating shadowband technique to make spectrally resolved measurements of the direct-normal, total horizontal, and diffuse horizontal irradiances. These parameters of the sky-radiance function are measured using the same detector (for a given wavelength), eliminating th...

In this paper, we aimed to clarify the problem of foam coverage dependence on wave fetch, which is interest in satellite microwave radiometry, but for controversial results were reported previously. The classical approach investigating developing waves was applied. That is, are considered as coming from coast under approximately constant wind velocity. study includes two scenes intensive kataba...

diation and radiobiological researches and radiation protection. The first two lines are included in the Topical Plan for Scientific Research of JINR and were concentrated on: • neutron spectrometry and radiometry, radiation monitoring; • investigation of radiation fields around thick targets; • physical support of radiobiological experiments; • shielding calculations and design; • investigatio...

We report the use of Heat transfer Module of COMSOL multiphysics and a technique based on Infrared Photothermal Radiometry to study the heat transfer of a homogeneous and isotropic solid material excited by a periodic laser beam on the front side of the sample, and an infrared detector on the rear side in order to obtain the evolution of the temperature difference with the exposure time. Also, ...

To describe human perception related phenomena, one can distinguish among three classes of quantities: psychological ones reflecting perception, quantities directly related to the physical stimuli and psychophysical quantities that can be measured using physical quantities, but which reflect some characteristics of the human sensory system. Related to vision the three classes are the terms rela...

Block-detection and three-dimensional moment algorithms are applied to determine the presence and orientation of cylinders in a three-dimensional image. The proposed method detects blood vessels in a three-dimensional tomographic image constructed by infrared radiometry. Based on the moment principle, the method can be employed to determine the centroid, diameter, and orientation of arbitrarily...

A new laboratory radiometric calibration process has been developed at Intergraph Z/I Imaging and is being implemented for both the DMC and RMK-D camera systems. This new capability enables the development of absolutely radiometrically calibrated products for scientific and remote sensing applications and improves general image color quality and color balance. Although many advanced CCD-based m...
