Inverse Scattering via Transmission Matrices: Broadband Illumination and Fast Phase Retrieval Algorithms

Interesting paper by people at Rice and Northwestern universities about different phase retrieval algorithms for measuring transmission matrices without using interferometric techniques. The thing with interferometers is that they provide you lots of cool stuff (high sensibility, phase information, etc.), but also involve quite a lot of technical problems that you do not want to…More

Focusing light through dynamical samples using fast continuous wavefront optimization

The guys at LKB keep going inside turbid media. This time, they have done it really fast. By using a phase spatial light modulator and with the help of a FPGA card, they were able to focus light through a scattering medium at a rate of ~4 kHz. This is trying to solve a common problem…More
