Major Geological Events Seem to Follow a Rhythmic Pattern of 27.5 Million Years, Researchers Call It Earth’s ‘Pulse' Dozens ...

Linear transforms — like a Fourier transform — are a key math ... high-resolution diffraction surfaces with the very specific patterns called for by the designs. If you are looking to get ...

Back in 1824, a French physicist named Joseph Fourier made a breakthrough that would fundamentally change our understanding of how Earth's atmosphere works. He discovered the greenhouse effect, which ...

The resulting signal, an interferogram, is a complex pattern that, through Fourier Transformation, is converted into a spectrum representing molecular absorption as a function of wavelength or ...

By altering the Fourier pattern period, a slight shift of the wavelength due to a change of the laser drive temperature or current can be measured. The selected VCSEL or laser diode can be dual-mode ...
