Measurement of Thermo-Elastic Deformation of an Optic using a Polarization Based Shearing Interferometer

, 2012
A shearing interferometer is presented which uses polarization control to shear the wavefront and to modulate the interference pattern. The shear is generated by spatial walk-off in a birefringent crystal. By adjusting the orientation of the birefringent

Analytical and Clinical Interference of Sample Hemolysis in Evaluating Blood Biochemical and Endocrine Parameters in Cows

Animals
Hemolysis is a common cause of errors in laboratory tests as it affects blood parameters and leads to a positive or negative bias. This study aims to examine the relationship between the level of hemolysis (expressed as cell-free hemoglobin concentration,

A battery-operated, stabilized, high-energy pulsed electron gun for the production of rare gas excimers

, 2011
We report on the design of a new type of electron gun to be used for experiments of infrared emission spectroscopy of rare gas excimers. It is based on a filament heated by means of a pack of rechargeable batteries floated atop the high-voltage power ...

Surface figure measurements of radio telescopes with a shearing interferometer [PDF]

, 1991
A new technique for determining the surface figure of large submillimeter wavelength telescopes is presented, which is based on measuring the telescope’s focal plane diffraction pattern with a shearing interferometer.

Implementation and application of an improved phase spectrum determination scheme for Fourier transform spectrometry [PDF]

Atmospheric Measurement Techniques
Correct determination of the phase spectrum is a highly relevant task in Fourier transform spectrometry for concluding which spectral distribution most likely gave rise to the measured interferogram.

Multicolored Femtosecond Pulse Synthesis Using Coherent Raman Sidebands in a Reflection Scheme

Applied Sciences, 2015
Broadband coherent Raman generation emerges as a successful method to produce multicolored femtosecond pulses and time-shaped laser fields. In our study, coherent Raman sidebands are generated in a Raman-active crystal, driven by two-color femtosecond ...

The Relationship between Land Subsidence and Water Use in Yazd-Ardakan Plain Using Sentinel-1 Images [PDF]

تحقیقات کاربردی علوم جغرافیایی
In arid and semi-arid regions, groundwater is more important for humans and ecosystems than surface water. Land subsidence is caused by the pumping and uncontrolled use of groundwater in an area.
