Abstract Measuring signatures of strong-field quantum electrodynamics (SF-QED) processes in an intense laser field is experimental challenge: it requires detectors to be highly sensitive single electrons and positrons the presence typically very strong x-ray ? -photon background levels. In this paper, we describe a particle detector capable diagnosing leptons from SF-QED interactions discuss le...

We demonstrate the detection of particles/contamination present on a structured surface using Coherent Fourier scatterometry (CFS) by applying filtering to scanned maps, which eliminates background effects due electronic noise as well structure itself. show that filters in space we can significantly improve capabilities particles structure.

hand gesture recognition is very important to communicate in sign language. in this paper, an effective object tracking and hand gesture recognition method is proposed. this method is combination of two well-known approaches, the mean shift and the motion detection algorithm. the mean shift algorithm can track objects based on the color, then when hand passes the face occlusion happens. several...

This application note will benefit chemical and material manufacturers concerned about micron and submicron par ticle contamination. Outliers are a common problem in many industrial applications. Outliers can be defined as particles that are significantly larger or smaller than the main particle size distribution, but which occur in a much lower frequency than the main par ticle size. As a simp...
