We formulate and study a one-dimensional single-species diffusive-delay population model. The time delay is the time taken from birth to maturity. Without diffusion, the delay differential model ...

Dynamically controlling terahertz wavefronts with cascaded metasurfaces. Advanced Photonics, 2021; 3 (03) DOI: 10.1117/1.AP.3.3.036003 ...

The transmitted wavefronts were visualized in the 0.12–0.23 THz range of frequencies using a state-of-the-art THz-field imaging technique 29, which enabled mapping of the electric-field ...

In conventional ultrasounds, variations in soft tissue structure distort ultrasound wavefronts. They blur the image and can hence prove detrimental to medical diagnosis. Researchers at the ...

They reported sensitivity of 15 deg/hr/Hz 2, Sagnac detection bandwidth of more than 1 kHz, and sensed a minimum rms rotation rate of 6.3 x 10 -3 deg/sec (22 deg/hr), which they say is about 40 ...

Such a hologram is then illuminated with a beam of reference light to recreate the spatial structure of wavefronts of the light reflected from the object, and as such its 3D shape.

Manufacturing 22-nm devices will require much more accurate imaging and overlay performance. To meet that performance ASML has introduced FlexWave programmable wavefronts.

Light Field Lab creates holograms with their directly emissive and modular SolidLight™ Surfaces, which are capable of forming dense converging wavefronts with billions of pixels at photonic ...
