Light is characterized by its fundamental properties, namely, amplitude, phase, wavelength, direction, frequency, speed, polarization, and coherence. In optical metrology, these fundamental properties of light are ingeniously utilized as information carriers of a measurand, enabling a wide range of ...

In addition, an MCP is dually symmetric; that is, it is excited by and emits light with identical helicity49,50. Therefore, an MCP must be completely decoupled from its enantiomer because photons radiated from the former cannot excite the latter. Using these properties, MCPs could be used as...
The color of the emitted light is determined by its wavelength that, in turn, depends upon ΔEg. The energy band gap (and hence the color of the emitted light) is determined by the semiconductor material and by doping and fabrication. The light is emitted from an LED within a very narro...

The incoherent light generated by the LEDs is channeled into a fiber optic bundle linked to a cylindrical lens for light sheet generation. The light produced by the LEDs was first characterized in term of its wavelength and illuminance properties with respect to input power and pulsing frequency....
Q2: Coded aperture imaging, as a lensless imaging technology, is characterized by its compact optical setup and easy implementation. How to establish the connection between the scene and the image, and how to reconstruct the image by solving the inverse problem is the key issue in encoded imagi...
