A Spatial Light Modulator Using Bso Crystals
The combmed use of the photoelectnc and electro-optic properttes of the BI,,SIO~~ (BSO)-crystal leads to a new posslblhty of reahzmg a spa&xl hght modulator Under certam geometrical condrtions, whxh will be discussed, It 1s possible to reahze, that the BSO-crystal becomes blrefrmgent depending on the local fiummance, the physxal connection between the dlstnbutlons of blrefrmgence and lllummance...
متن کاملBSO Crystals for the HHCAL Detector Concept
We report an investigation on optical and scintillation properties and radiation hardness of four 20 cm long BSO crystals grown at SIC for the HHCAL detector concept. Their optical and scintillation properties, such as longitudinal transmittance, light output and light response uniformity, were measured before and after γ-ray irradiation. Progresses are observed in optical quality, light output...
متن کاملMeasurement of the nonlinear index n(2) of BSO crystals.
If authors will state in their covering communications whether they expect their institutions to pay the publication charge, publication time should be shortened (for those who do). Photorefractive materials are now widely studied for their large nonlinear optical properties. Large gain values in two-beam coupling or degenerate four-wave mixing experiments are easily available using a low-power...
متن کاملReal-time Sub-pixel Cross Bar Position Metrology
M any measurement application fields need to calculate cross bar intersection locations of horizontal and vertical bars. The system we developed and that we present in this paper is an embedded system that measures cross bar positions with sub-pixel accuracy on 1024 1024 pixel images delivered by a camera at a 50MHz data rate in real time. This is done using an algorithm that looks for intersec...
متن کاملPulse shaping with birefringent crystals: a tool for quantum metrology.
A method for time differentiation based on a Babinet-Soleil-Bravais compensator is introduced. The complex transfer function of the device is measured using polarization spectral interferometry. Time differentiation of both the pulse field and pulse envelope are demonstrated over a spectral width of about 100 THz with a measured overlap with the objective mode greater than 99.8%. This pulse sha...
