Sentences with phrase «enough photons of light»

Dr Jeffrey Simpson of the AAO said it takes about an hour to collect enough photons of light for each star, but «Thankfully, we can observe 360 stars at the same time using fibre optics,» he added.

If even a small amount of energy from phonons (the sound units that carry the energy through the germanium or silicon, much as photons are the units of light) hit the detector, it can be enough to make the device lose superconductivity and register a potential dark matter event through a device called a superconducting quantum interference device, or SQUID.

It pumps 20 liters (about 5.3 gallons) of seawater and plankton per second through a «light tight» collection chamber large enough to capture even fast swimmers and keep them inside long enough for the device's fiber - optic instruments to record and measure, in photons per liter, the size, duration, and number of an organism's flashes.

She assembles sensors keen enough to detect a single photon of light.

«You need a lot of silicon to stop all of the photons, but you can't have enough silicon in the line of sight to absorb all of the light.»

A team of researchers has built an array of light detectors sensitive enough to register the arrival of individual light particles, or photons, and mounted them on a silicon optical chip.

In five minutes, the scope collected a mere 11 photons of light from the glow — tiny but enough for Swift's sensitive instruments to track the detonation with accuracy.

The ripples are so large that by the time the photons detected by COBE were emitted, the Universe was simply not old enough for a light signal to have crossed from one side of a COBE ripple to the other.

«In really dim light, our cones don't receive enough photons to work, but they continue to emit a low - level baseline signal to the rest of the retina that is independent of light,» he explains.

Green - light photons hold 240 kJ / mole of energy, which is enough to bend (but not break) the rhodopsin molecules in our retinas that trigger our photosensitive rod cells to fire.

Deborah Jackson, a senior member of the quantum computing technologies group at the Jet Propulsion Laboratory (JPL) in Pasadena, California, assembles sensors keen enough to detect a single photon of light.

Within that plane, photons are so concentrated that they interact with the dye in pairs, each of which has enough energy to light up the dye molecules.
