Gillooly, Andrew M. ; Dobb, Helen ; Zhang, Lin ; Bennion, Ian (2004)

A chirped moiré fiber Bragg grating has been demonstrated to be capable of measuring the magnitude, position, and footprint of a transverse load. The device provides an average spatial resolution of 164 μm and has a load accuracy of 0.15 N/mm, or 50 με. © 2004 Optical Society of America.
