photon noise 中文意思是什麼
photon noise
解釋
光子雜訊-
It has been shown that : the little indentation which represents the quantum noise of the system appears in the evolution curves ; the quantum noise which is caused by virtual photon field gradually becomes weak when w increases, the quantum noise increases when n increases ; the virtual photon process make the antibunching effect strengthen, make the squeezing degree deepen obviously, and lead to the additional vibration of entropy, the oscillation extent of the additional vibration of entropy increases when n increases and decreases when co or g increase. besides, the quantum dynamics of two coupling atoms interacting with a single mode ligh t field in a kerr medium is studied in this paper ; the influences of the kerr effect on the mean photon number, the degree of second order coherence of field, the evolution of the field entropy and the squeezing effect are also discussed
）的增大，量子噪聲分別減小和增大；虛光子過程使光場的反聚束效應增強，使光場的壓縮程度明顯加深，並引起了附加的「熵振蕩」 ，這種附加「熵振蕩」的幅度將隨著光場初始平均光子數（ ? ）的增加而增大，隨著光場頻率和原子間耦合系數g的增大而減小。本文還研究了充滿kerr介質腔中「耦合雙原子-單模光場」相互作用系統的量子動力學性質，研究了克爾效應對場的平均光子數、二階相干度、場熵演化特性及光場壓縮效應的影響。 -

We adopt double alkali cathodal tube 9789qb, which was made by emi corporation in england, as our photomultiplier, whose spectrum ranges between 300nm to 650nm, with less noise counters and single - photon apices, which make it suitable as a single - photon - counter. the disparted - voltage device is designed in a reasonable way and the cooling system of iquefied nitrogen which makes it small in size, simple in structure, easy in processing, cheap in cost and good in performance
該管型的光譜范圍在300 650nm ，具有暗計數少，有單光子峰的特點，適于做單光子計數器；本文的光電倍增管分壓器設計合理而冷卻系統採用液氮，該系統體積小、結構簡單、加工便利、成本低廉且性能良好。 -
We consider testing it using photon counting mode of photomultiplier pmt to transform light signals into electric signals. much of the noise can be eliminated with an amplitude discriminator
