Laser-induced plasma spectroscopy (LIPS) made a great progress as a potential technology for nuclear analysis and detection. In this article, the instrumentation of LIPS for In-situ and stand-off application was introduced. The application of LIPS in nuclear industry was reviewed, such as international nuclear safeguard, nuclear materials analysis, hazard material detection and monitoring process, etc.
Abstract: An instrument was built to measure the output fluorescence response characteristics of a 248nm KrF laser using 4mm-thick fluorescent glass as a screen. Experiments show when irradiated laser intensity is no more than 0.7J/cm2, the fluorescent response is linear. And the fluorescent spot intensity distribution was spatial coherent with the output beam profile distribution of the LPX-150. So we can use high-homogeneity optical glasses as fluorescence wavelength conversion material in beam profile measurements.
With the rapid development of remote sensing technology and variety of earth observation satellites have been
successfully launched, the volume of image datasets is growing exponentially in many application areas. The Contentbased
image retrieval (CBRSIR), as an efficient means for management and utilization of the information in image
database from the viewpoint of comprehension of image content, is applied on the remote sensing images retrieval.
However, one kind of features always can’t express the image content exactly. So, a multi-feature retrieval model based
on three color features and four texture features is proposed in this paper. The experiment results show that the multifeatures
model can improve the retrieval results than other model just by each singular feature.
