   Keywords : Characterization; Characterization Microscope; Microscope; Confocal; Amorphous Nonlinear Medium; Laser; Laser Diodes; Infrared Laser; Infrared; Optics; Nonlinear Optics; Nonlinear; White Light Emission; Infrared to White Light; Physics and Astronomy;

   Abstract : A confocal microscope is built to examine molecular powders, and in particular the (PhSn)_4S_6 cluster, that emits white light when irradiated with infrared laser light. The confocal microscope operating at long working distances is assembled and characterized. READ MORE

4. 3. Characterization of Terahertz Radiation Generated in an Organic Crystal

   University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

   Author : Åsa Bengtsson; [2016]
   Keywords : Nonlinear optics; Terahertz radiation generation; Optical rectification; Difference frequency generation; Organic crystal; DSTMS; Physics and Astronomy;

   Abstract : The terahertz region of the electromagnetic spectrum is an important research area allowing insights into fundamental science such as inter-molecular interactions, and with applications in the environmental, medical and security field. Using femtosecond lasers, it is possible to design compact and efficient terahertz generation schemes, resulting in few-cycle broadband pulses. READ MORE

5. 4. Optomyography - Detection ofmuscle surface displacement using reflective photo resistor.

   University essay from KTH/Medicinska sensorer, signaler och system

   Author : Jammalamadaka Raghavendra; [2014]
   Keywords : Optomyography; Photoelectric sensors; Reflective photo resistor;

   Abstract : A human body can carry out many physiological complex processes which can be mechanical, electrical or bio-chemical. Each mechanical activity generates a signal that describes the characteristics of the particular action in the form of pressure or temperature. READ MORE
