Laser safety importance in clinical laser applications

Introduction: By introducing of laser systems and their continuous development, a new chapter of laser systems applications in a variety fields including research and clinical science in addition to the therapeutic, diagnostic applications were available for medical professionals in various fields. Most lasers emit radiation with intrinsic probable risks where in laser-tissue i...

Let’s take Laser safety seriously

Nowadays laser is extensively used in various industrial, communicative, medical, and other fields. Using laser in medicine has enabled physicians to perform the most accurate and finest operations within few minutes. Non-observance of safety points during laser performance could be seriously harmful for the medical staff and the patient. Therefore, in order to prevent the possible damage of th...

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...

Principles of airborne laser scanning

Figure 1 represents the paradigm of laser scanning. A paradigm as generally known focuses on the basics and ignores minor matters. The paradigm of laser scanning can be characterised in the following way: • A bundle of 3D-vectors, positioned by GPS and oriented by IMU • Active sensors Figure 2 illustrates the paradigm of Stereo-Photogrammetry and can be characterized by: • 2 directed bundles, w...
