In conventional Kerr and Faraday microscopy, the sample is illuminated with plane-polarized light, a magnetic domain contrast generated by an analyzer making use of or rotation. Here, we demonstrate possibilities analyzer-free magneto-optical microscopy based on magnetization-dependent intensity modulations light. (i) The transverse effect can be applied for in-plane magnetized material, as dem...

Received Day Month Year Revised Day Month Year We present theoretical predictions for the spectral, temporal and intensity signatures of the electromagnetic radiation emitted during the process of the gravitational collapse of a stellar core to a black hole, during which electromagnetic field strengths rise over the critical value for e + e − pair creation. The last phases of this gravitational...

A new full field optical technique 'Coherent Gradient Sensing' (CGS) is developed and used to study crack tip deformations in transparent as well as opaque solids. A first order diffraction analysis is provided for the technique and its feasibility is demonstrated both in transmission and reflection modes. Preliminary results from the dynamic crack growth experiment clearly demonstrate the capa...
