control of the optical properties of nanoparticles by laser fields

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...

Quality Assessment of Dtm and Orthophoto Generated by Airborne Laser Scanning System Using Automated Digital Photogrammetry

The approach of using an airborne laser scanning for DTM generation has made great progress recently. However, it is not always clear the reliability and the quality of the geometry that characterise the generated DTM. Thus, a special test was conducted to assess the quality and the reliability of the generated DTM via an airborne laser scanning system. To perform this test, an airborne laser s...

Improvements in DTM generation by using full-waveform airborne laser scanning data

Compared to laser radar systems based on the conventional discrete echo approach, direct detection laser radar systems with echo signal digitization and subsequent full-waveform analysis like the RIEGL LMS-Q560 provide valuable additional information on the target’s properties. This additional information can be used in the course of the mandatory processing task of classifying the measurement ...

Analysis of Planimetric Accuracy of Airborne Laser Scanning Surveys

With the increasing pulse rates of airborne laser scanners point clouds become an interesting data source for mapping beyond the production of digital terrain models. Whereas height accuracy of point clouds is of prime importance for terrain models, mapping of buildings and other objects also requires an analysis of planimetric accuracy of point clouds. This paper presents a methodology to esti...

Accuracy Study of Airborne Laser Scanning Data with Photogrammetry

This paper describes an accuracy study of airborne laser scanning data obtained by the Airborne Topographic Mapper (ATM) laser system over Ocean City, Md. The ATM is a conical scanning laser altimeter developed by NASA for precise measurement of surface elevation changes in polar ice sheets, ocean beaches and drainage systems. First, we determine the “internal" accuracy of the system by compari...
