WebAnswer: An altimeter is basically a barometer that works backwards. If you buy a barometer for your home, the first thing you need to do is set the prevailing pressure based on your location. You can look this up on any weather app, turn the little adjuster in the back until the correct pressure ... WebThe polarization properties of a sample can be characterized using a Jones matrix. To measure the Jones matrix without assumptions of the sample, two different incident states of polarization are usually used. This requirement often causes certain drawbacks in polarization-sensitive optical coherence tomography (PS-OCT), e.g., a decrease in the …
