Spatially resolved, single-ended two-dimensional visualization of gas flow phenomena using structured illumination
A method for 3D mapping of scattering particle concentration in a gaseous medium based on the back-scattered light in a single direction has been demonstrated. The technique is originally developed for microscopy but now implemented on larger-scale samples. The technique used is known as structured illumination, where a sinusoidal grid pattern is projected onto the medium, thus marking the in-focu
