Scientists have realized a Fourier-transform spectroscopy scheme based on a wavefront-division scanning interferometer that operates down to wavelengths as short as 40 nm, benefitting studies of ...

When last we saw [xoreaxeax], he had built a lens-less optical microscope that deduced the structure of a sample by recording the diffraction patterns formed by shining a laser beam through it. At the ...

Figure 1 compares the SWIFTS principle with grating spectrometers and Michelson. The observations from the comparison are: A Fourier-transform spectrometer is shown in a Michelson configuration. A ...

Over at Quanta Magazine [Shalma Wegsman] asks What Is the Fourier Transform? [Shalma] begins by telling you a little about Joseph Fourier, the French mathematician with an interest in heat propagation ...

In the early 1940s, the first commercial dispersive spectrometers emerged for UV-Vis applications. This technology is based on the dispersion of light in dependence of its wave-lengths. The dispersion ...
