Fine-scale exogenous attention within the foveola selectively enhances contrast gain at low-to-mid spatial frequencies while increasing response gain across a broad spatial frequency range.

Current technologies to modulate light in free space are bulky, slow, static, or inefficient. Now researchers have developed a compact and tunable electro-optic modulator for free space applications ...

Doing more with less in electronics often means improving power density. One of the new areas garnering attention involves applying a variety of advanced modulation techniques, including PWM and space ...
