Theoretical and experimental study on the conoscopic interference in uniaxial crystal (Ca_0.28Ba_0.72)_x(Sr_0.60Ba_0.40)_1‐xNb₂O₆

Abstract

Theoretical and experimental study on the conoscopic interference in uniaxial crystal (Ca 0.28 crystals were observed with the beams transmitting along optical-axes and deflection optical-axes from 0 to 140°. Endo-exo variation from looseness to tightness of conoscopic interference patterns were analyzed in theory. A hyperbolic black cross of interference patterns were observed as well as its formation process was proposed in this paper. Also, the inferences of the birefringence with different Ca 2+ -doped were obtained in this investigation.

Conoscopic figure: a complex consequence of a not so simple phenomenon

“…Conoscopic figures were discussed in [7][8][9][10][11][12][13][14]. The authors considered simple hands-on experiments that allowed for an observation of conoscopic figures of transparencies [7][8][9] and simple arrangements for observing conoscopic figures of crystals [10][11][12][13][14].…”

More details were given for a theoretical analysis of conoscopic figures [9,13,15] and propagation of electromagnetic waves through other anisotropic media [16,17].…”

“…Conoscopic pattern informativity provides for the possibility to determine orientation and nature of optical indicatrix, measure an angle between the optical axes of a biaxial crystal, determine an optical sign of the crystal, detect optical axes dispersion, identify qualitative and quantitative changes in the optical indicatrix in response to external action, etc. [1][2][3][4][5][6][7][8][9][10][11]. Conoscopic method is one way to analyze the properties of optical crystals, which allows to determine their functionality, and which has long and successfully used in scientific research and a variety of optical devices.…”
