Monitoring error compensation in general optical coatings.
Error compensation in optical monitoring was demonstrated many years ago for narrow bandpass and edge filters. It is shown here that the compensation effects can apply to a broader range of more general coatings. This is illustrated with a very broadband antireflection coating design of 20 layers and a ramp design of 13 layers. The choice of monitoring wavelength and monitoring strategy are imp...
متن کاملAn adaptive error-resilient video encoder
When designing an encoder for a real-time video application over a wireless channel, we must take into consideration the unpredictable fluctuation of the quality of the channel and its impact on the transmitted video data. This uncertainty motivates the development of an adaptive video encoding mechanism that can compensate for the infidelity caused either by data loss and/or by the post-proces...

15 صفحه اولan infinite planar array of rectangular microstrip patch antenna analysis
the methods which are used to analyze microstrip antennas, are divited into three categories: empirical methods, semi-empirical methods and full-wave analysis. empirical and semi-empirical methods are generally based on some fundamental simplifying assumptions about quality of surface current distribution and substrate thickness. thses simplificatioms cause low accuracy in field evaluation. ful...
15 صفحه اولError Analysis for Dual-beam Optical Linear Polarimetry
In this paper we present an error analysis for polarimetric data obtained with dual-beam instruments. After recalling the basic concepts, we introduce the analytical expressions for the uncertainties of polarization degree and angle. These are then compared with the results of Monte-Carlo simulations, which are also used to briefly discuss the statistical bias. Then we approach the problem of b...
