In this interview, Sue Berets, the Applications Scientist at Harrick Scientific, talks to AZoM about specular reflectance measurements and the difference between absolute and relative. Please tell us ...

all of which require access to accurate relative time-space positioning information (R-TSPI) between platforms. In this article, we present the foundation for a generic approach to relative navigation ...

It is useful for expanding the effective aperture of the interferometer, in one axis. The measurement area is around the same size as the beam when a laser interferometer's round measurement beam ...

The Standard Deviation is the basic metric to measure volatility. However, the Standard Deviation is an absolute measurement, not a relative measurement. To compare the volatility of two or more data ...

With the continuous advancement of photoelectric performance in major equipment and advanced instruments, traditional optical elements are increasingly inadequate to meet the demands of modern systems ...
