Abstract: The conventional laser triangulation displacement sensor (LTDS) is difficult to achieve large dynamic range and high precision measurement simultaneously, since LTDS is affected by factors ...

Abstract: The rigorous diffraction boundary problem for a semitransparent slotted semi-infinite cone is considered. Slots are periodically cut along its generatrices from the cone tip. The source ...

Scientists from the UK and China have developed a lateral-graded multilayer grating that addresses a key challenge in tender X-ray RIXS technique. Demonstrated at the I21 beamline in Diamond Light ...

In 1980, France took a step into the future when the telecom companies introduced the Minitel system — a precursor to the Web where users could shop, buy train tickets, check stocks, and send and ...
