The Swedish physicist prized Michelson's use of his interferometer in metrology and, in particular, for determining experimentally the length of the international metre.
Spie, of course, is deeply involved in metrology in virtually any branch of optics or photonics you might name.
The pressure for standardization also affected metrology .
New instantaneous PMI techniques can operate in these production environments with success, but care must be taken regarding systematic errors to assure good metrology .
A special symposium on photonics time and frequency metrology focused on the control and use of mode-locked lasers in producing frequency combs.
Environmental effects can be an issue in more conventional metrology applications as well, notes Robert Stoner, vice president of metrology and optical systems at Zygo Corp.
As LEDs and LED arrays become more prevalent in illumination and communications, precise metrology of these devices will become increasingly important.
One example where improved metrology would be highly beneficial is in the commercial production of high-accuracy pressure-measuring instruments.
Whilst rarely thought of as technology in itself, metrology will continue to be a developing and defining feature of the next ten years: defining and setting common standards of measurement.
We also divert a low-power sample of the radiation to obtain in-situ metrology .
