There are tradeoffs between these gratings: holographic gratings produce less stray light while ruled gratings are more reflective, resulting in higher sensitivity.

Such polymer gratings show promising potentials for the fabrication of low-order distributed feedback polymer lasers.

The technique of fabricating concave gratings in PMMA by double X-ray exposures is described.

Influences of processing modifier, heat stabilizer and lubricant on the surface glossy degree of PVC protective gratings were studied.

An improved method of cascaded long-period fiber gratings (LPFGs) is proposed, which can effectively broaden the resonant spectrum bandwidth of LPFGs.

According to characteristics of lathe cutting, two gratings are adopted to measure changes of the diameter when work piece being processed, then calculating the diameter.

And that in Turin there are people who sleep on the pavements, over warm cellar gratings.

Photocopy of high precision circular gratings with high and stable yields is the only way to meet the domestic needs which increase gradually.

In the system two coded gratings are inversely imaged to each other by a lens, and the tested phase object is placed between and imaged onto an observation screen.

The results of analysis indicate that the moiré gratings technology can be well applied in fabricating the high-performance phase-shifted and apodised long-period fibre gratings.

It is also shown that only when the gratings are cylinder or plane ones, the second order sagittal anastigmatic circular field and meridional non defocus flat field spectral images can be formed.
