Improved measurement of deformation
In a strain sensing system in which a strained grating is illuminated with a pair of beams chosen from three possible beams to sense strain in two dimensions, an arrangement is disclosed of two beam splitters, as least one plane mirror, and three tilted mirrors, all fixed to a support plate and whic...

| Zusammenfassung: | In a strain sensing system in which a strained grating is illuminated with a pair of beams chosen from three possible beams to sense strain in two dimensions, an arrangement is disclosed of two beam splitters, as least one plane mirror, and three tilted mirrors, all fixed to a support plate and which can supply the three required illuminating beams. |
