Ultra-high dynamic range electro-optic sampling for detecting millimeter and sub-millimeter radiation
Time-domain spectroscopy using coherent millimeter and sub-millimeter radiation (also known as terahertz radiation) is rapidly expanding its application, owing greatly to the remarkable advances in generating and detecting such radiation. However, many current techniques for coherent terahertz detection have limited dynamic range, thus making it difficult to perform some basic experiments that ...
متن کاملAn Electro-optic E-field Probe
A novel concept for an electric-field (E-field) probe is proposed. The reactive near field, induced by an impinging E-field, of a very short, short-circuited receiving dipole is measured with the aid of an electro-optical modulator. The modulator is designed as a Fabry-Perot etalon. The laser light guided in the etalon is modulated proportionally to the near field of the antenna. The advantage ...
متن کاملColor Calibrated High Dynamic Range Imaging with ICC Profiles
High dynamic range (HDR) imaging has become a powerful tool in computer graphics, and is being applied to scenarios like simulation of different film responses, motion blur, and image-based illumination. The HDR images for these applications are typically generated by combining the information from multiple photographs taken at different exposure settings. Unfortunately, the color calibration o...
متن کاملA Ternary Digital to Analog Converter with High Power Output and 170-dB Dynamic Range
A prototype of a very high dynamic range 32bits Digital to Analog Converter (DAC) was designed and built for the purpose of direct auditory stimulus generation. It provides signals from less than 100 nV up to 50 Watts peak power output, driving a 32-Ohms earphone or speaker. The use of ternary cells makes possible a 170 dB dynamic range that is basically limited by thermal noise only.
متن کاملIntegrated high-power electro-optic lens and large-angle deflector.
We present a theoretical discussion and experimental demonstration of what to our knowledge is a novel integrated electro-optic lens and beam deflector fabricated in lithium tantalate. The cylindrical lens collimates Gaussian beams as small as 4 mum in diameter, whereas the independently controlled deflector is capable of scanning the collimated beam through an angular range of nearly 20 degrees .
