The first order quantum correction is obtained for the characteristics of spontaneous radiation as a functional of a classical trajectory by means of quasi-classical trajectory–coherent states method for relativistic spinless particle in an arbitrary external electro-magnetic field. It is shown that the power of boson radiation coincides up to O (ħ2), ħ → 0 with the power of electron radiation averaged over spin states calculated by the TC-states of the Dirac equation. Certain specific examples are considered on the base of a general formula for the radiation power in the non-relativistic appr

The article deals with the experimental study of the compensation method for atmospheric attenuation of laser radiation in active electro-optical remote sensing systems with dynamic spectral processing of optical signals that provides an increase of target image contrast. The compensation method for atmospheric attenuation of laser radiation in active electro-optical systems consists in forming the spectral intensity of the probing radiation not only on the basis of a priori data on the spectral features of the reflecting surfaces of the target and the background, but also taking into account

The process of dynamic spectral processing of optical radiation in the active electro-optical system that provides enhancement of the contrast of the image target has been experimentally researched. A routine of experiment and a diagram of an experimental setup have been developed. The sources of optical radiation in the transmitting part of the active electro-optical system were three semiconductor lasers operating in the ranges of the red, green, and blue spectral regions. Absorption optical filters were used in the experiment as the elements simulating the spectral properties of the reflect

The design of the ITER Toroidal Field (TF) coils requires an insulation system that is amenable to the very large scale vacuum impregnation processes planned for the construction of these devices, and that will provide reliable electro-mechanical performance after radiation exposure. To address this need, CTD has developed an epoxy/cyanate ester resin system designated CTD-425. This material meets the processing requirements for use in the TF coils, and cyclic mechanical testing of conductor assemblies has demonstrated its electro-mechanical strength after 60,000 mechanical cycles.

Electromagnetic interference (EMI) can degrade device performance, particularly a sensitive device such as magnetic recording heads. A high applied voltage generates a high electric field in order to break the electrical air gap during a gold ball bonding process.

A novel optical measurement technique for the in situ determination of surface temperature is presented. The technique employs modulation of the object temperature by an energy source of high intensity, such as a laser. By modulation of the temperature at the point from which the emitted spectrum of electro-magnetic radiation is being monitored, routine calculations involving the observed modulated component of the radiation spectrum will determine the temperature and, for some conditions, emissivity. The region to be measured is thus defined by the intersection of the laser and the beam which
