1. I have also indicated a photon reaching the earth from a distant star.

2. But here things are very different: each individual photon behaves like a wave entirely on its own!

3. This light is tuned so that the photon energy exactly matches the desired atomic transition energy.

4. The photomultiplier was operated in the single photon counting mode.

5. How can it be that by allowing the photon an alternative route, we have actually stopped it from traversing either route?

6. Photon Cannons, or the little hand thingies.

7. A real or virtual photon may spontaneously annihilate.

8. The photon is the carrier of electromagnetism.

9. Detection of the photon rest mass is dependent on a rotating torsion pendulum method, where the precision of the experimental result is mainly dependent on the amplitude of the modulating signal.

10. The stimulated photon echo in degenerate two-level system has been studied.

11. The opinions of mode degeneracy and photon commutation are presented to explain the above method.

12. A photon counting image model based on avalanche photodiode(APD)arrays response characters and Poisson point process of photons was developed.

13. Analyzing the carrier density and photon density of VCL in active region, the physical mechanism of gain clamping was revealed.

14. Photon switching technology is a fundamental solution to the speed unmatch between optical fibre system with high transmission speed and electronic switching system with slow switching speed.

15. Suppose the intensity is lowered to a level at which only a single photon at a time encounters the crystal.

16. Matching one discreteness with another Bohr supposed that the energy loss was radiated as a single photon.

17. To see how the array of possibilities is again the Riemann sphere,[sentence dictionary] imagine the photon to be travelling vertically upwards.

18. The crystal acts as an analyser which ascertains whether or not the photon has polarisation perpendicular to the optical axis of the crystal.

19. When an electron collides with a positron the two particles disappear, or annihilate, to create a high-energy photon.

20. Compton proposed that the quantum of light could act as if it were a particle, and he christened this the photon.

21. As a result of this(Sentencedict.com), some eyes are capable of detecting a single photon.

22. We discuss the relationship between the integrability and the non classical effects of the two photon J C model by means of numerical method, .

23. The technologies of radionuclide section imaging tomograph included single photon emission computed of tomograph (SPECT) and positron emission computed tomograph (PET).

24. The laser pulse modulation system has been used in a picosecond time-correlated single photon counting spectrometer with perfect effect.

25. China accounted for about a third of the market for global solar cell production in 2008 while Europe's share declined to about a quarter, according to a survey by German industry publication Photon.

26. Complicating things, as usual, is the Heisenberg indeterminacy principle, which puts strict limits on how precisely one can measure the frequency of a single photon.

27. The meter adopts embedded computer PCM3370E as the system core for control and data processing, to realize laser, photon counter and gating circuit timing control and visibility inversion.

28. And the decay rate of these deviations depends on not only the carrier lifetime but also the photon lifetime, which is different from that of an ordinary diode laser experiencing turn-on process.

29. This may occur long before actual entry of the photon belt.

30. To explain this phenomenon, a theory in which the distance resolution of 3D active imaging systems is determined by both the photon shot noise and the subinterval width is developed.
