Laser Speckle Imaging of a Finger by Scattered Light Optics
We have demonstrated Laser speckle imaging of a finger with an optical configuration based on scattered light detection. Laser light enters a light-guide from its edge and propagates inside. A finger in contact with the light-guide scatters the light and the leaking light is imaged by a camera placed nearby. The speckle image fluctuates with time because the light scattered by the blood flowing...
متن کاملTwo-level laser light statistics
The statistics of the light emitted by two-level lasers is evaluated on the basis of generalized rate equations. According to that approach, all fluctuations are interpreted as being caused by the jumps that occur in active and detecting atoms. The intra-cavity Fano factor and the photo-current spectral density are obtained analytically for Poissonian and quiet pumps. The algebra is simple and ...
متن کاملScattered light fluorescence microscopy: imaging through turbid layers.
A major limitation of any type of microscope is the penetration depth in turbid tissue. Here, we demonstrate a fundamentally novel kind of fluorescence microscope that images through optically thick turbid layers. The microscope uses scattered light, rather than light propagating along a straight path, for imaging with subwavelength resolution. Our method uses constructive interference to focus...
متن کاملgradual erasure of subjectivity: a study of samuel beckett’s trilogy in the light of postmodernism
ساموئل بکت بیشتر از هر نویسنده دیگری در نیم? دوم قرن بیستم با گفتارش زمان? ما را به آستان? از هم پاشیدگی کشانده است، آستانه ای که در آن مدرنیته با سرانجام گریزان اما غیرقابل اجتناب خود مواجه می شود. در این تحقیق روی مفهوم فردیت و محو آن در دوران پسامدرن تاکید شده و در طی آن سعی شده است که فردیت مدرن و پسامدرن در رمان های سه گانه بکت بررسی گردد. تحقیق حاضر یک بررسی کتابخانه ای و کیفی بر روی سه ر...
15 صفحه اولFluctuations in Scattered Light
Fluctuations in scattered light constitute some of the most familiar natural optical phenomena, including the twinkling of starlight, the glittering of sunlight on a rippled water surface and the shimmering of distant objects on a hot day [1]. These effects are geometrical in origin being a consequence of refraction by large-scale random variations in refractive index. Fluctuations of this kind...
