Lightbeam (called Collusion in its experimental version) was an add-on for Firefox that displays third party tracking cookies placed on the user's computer while visiting various websites. It displays a graph of the interactions and connections of sites visited and the tracking sites to which they provide information.
The chopper is used to modulate the intensity of a light beam, and a lock-in amplifier is used to improve the signal-to-noise ratio. To be effective, an optical chopper should have a stable rotating speed. In cases where the 1/f noise is the main problem, one would like to select the maximum chopping frequency possible. This is limited by the ...

When the incident light beam is at Bragg angle, a diffraction pattern emerges where an order of diffracted beam occurs at each angle θ that satisfies: [3] = Here, m = ..., −2, −1, 0, +1, +2, ... is the order of diffraction, λ is the wavelength of light in vacuum, and Λ is the wavelength of the sound.

The previous record had been set with a one-way detection of laser light from Earth by the Galileo probe, of 6 million km (3.7 million mi) in 1992. In January 2013, NASA used lasers to beam an image of the Mona Lisa to the Lunar Reconnaissance Orbiter roughly 390,000 km (240,000 mi) away.

A diffractive beam splitter can generate either a 1-dimensional beam array (1xN) or a 2-dimensional beam matrix (MxN), depending on the diffractive pattern on the element. The diffractive beam splitter is used with monochromatic light such as a laser beam, and is designed for a specific wavelength and angle of separation between output beams.
Nickelodeon is continuing its tradition of broadcasting an NFL playoff game in 2025. Here's how to watch the broadcast for the Texans-Chargers game.
