Abstract Optical encryption strategies utilizing fully coherent light have been widely explored but often face challenges such as speckle noise and beam instabilities. In this work, we introduce a novel protocol for multi-channel optical information

Time-resolved terahertz spectroscopy is used to investigate formation and ultrafast long-distance propagation of electron–hole plasma in strongly photoexcited GaAs and InP. The observed phenomena involve fundamental interactions of electron–hole

The mutual optical intensity (MOI) model is a partially coherent radiation propagation tool that can sequentially simulate beamline optics and provide beam intensity, local degree of coherence and phase distribution at any location along a beamline.

The intensity distributions and statistics of partially coherent light fields with random fluctuations have proven to be more robust than for coherent light. However, its full potential in practical applications has not been realized due to the lack

Combining wave optics propagation and geometric ray tracing, the mutual optical intensity (MOI) model is extended to quantitatively simulate the propagation of partially coherent light through a kinoform lens at high speed. The MOI model can provide

Microscope-based Laser Doppler vibrometers (LDV) are optical instruments using laser Doppler interferometry to measure the motion of vibrating structures. As laser vibrometers measure without contact, they are also widely used for the characterizatio

Optical resonances of a metallically coated wave-chaotic microcavity are investigated. Mode resonances with a low-contrast quality factor and distinct field patterns are demonstrated. Unlike the resonances in the dielectric chaotic-wave cavity where
