| In the early 1880s, he used a wavelength of light to determine the length of the meter, a major refinement in metrology. |
| Spie, of course, is deeply involved in metrology in virtually any branch of optics or photonics you might name. |
| He soon rose to be superintendent of the division at the NPL that covered metrology in general. |
| The EEI will allow program participants to determine the best approach to EUV wavefront metrology for tool manufacturing. |
| A special symposium on photonics time and frequency metrology focused on the control and use of mode-locked lasers in producing frequency combs. |
| If PCFs fulfill their potential, they could have important applications in spectroscopy, metrology, biomedicine, imaging, and telecommunications. |
