Examples are used to show the development trends of optoelectronic complexes for the diagnosis and certification of continuous-spectrum radiation sources under laboratory, shop, and field conditions. Questions of the metrological assurance of the measurements are considered.
This paper describes a spectrophotometric apparatus intended for measuring the spectral directed transmittance of optical elements with an aperture up to 280 rum in the visible and near-IR regions with an absolute measurement error that does not exceed 1%. (c) 2008 Optical Society of America.
This paper proposes a method of measuring the irradiance from powerful optical-radiation sources, based on beating a solid-state radiation element, after which a photoelectric method is used to record the flux re-emitted by the element. The spectral range in which the secondary flux is recorded is chosen in a region where the emissivity of the material of the element. is independent of temperature. A prototype of the measurement device has been developed Comparative measurements of the irradiance in the 10-100-W/cm(2) range from a continuous electric-arc source (a dismountable-metal xenon lamp with, a-power of 55 kW),using the prototype and a disk graphite calorimeter, showed satisfactory agreement, of the results. The measurement error is about 10%. (C) 2003 Optical Society of America.
The results are presented on experimental investigations of action onto an optical glass BK-7 and some other materials of a CO2 laser radiation with the pulse duration of 20-70 mu s and the energy density of 0.1-3 J/cm(2). The dynamics of a thermal response, temperature of heating and emissivity of irradiated glass samples are under consideration. The results obtained can be used in imaging techniques for objects selection.
Based on a proposed classification, possible approaches to the development of dynamic simulators of IR scenes are considered. These simulators generate the radiation of observable objects and the background accompanying them for the testing of optoelectronic devices in the IR. A review of existing dynamic scene simulators is presented.
