In the same way as the traditional optical interference technique, shearography obtains object deformation information by obtaining the phase, and the measured object is often dynamic in practical ...

Most biomolecules are chiral. Circular dichroism (CD) spectroscopy is typically used to provide information about that chirality. But the data for mixtures of biomolecules can be difficult to ...

A general-purpose vector signal analyzer offers a low-cost, flexible option for measuring the frequency settling time of PLLs. By Douglas Olney, Keithley Instruments Inc. The frequency-settling time ...
