For this, it’s crucial to understand the behavior of light within the optical fiber. The path taken by light inside the fiber is termed a “mode.” Each mode represents a unique trajectory.

The driver is taking two tourists down a nature path in a green car ... as the answer is below. How can optical illusions and brainteasers help me? Engaging in activities like solving optical ...

In traditional imaging, one tries to create a perfect image directly. In computational imaging, a distortion is added to the optical path, so that the recorded picture no longer resembles the object.

Our research interests include extending the depth of field of imaging systems, increasing image resolution beyond Rayleigh's resolution criterion, and quantifying the optical path length ...

We can use such information to construct a two-dimensional map of optical path lengths, and convert that to the surface profile or the refractive index variation of a specimen. We introduce ...
