Noise properties in a two-arm microscope imaging system with classical thermal light.

چکیده
We present an analysis of the noise properties in a two-arm microscope imaging system. The aperture of the reference lens affects the imaging quality significantly. Using large apertures will enhance the resolution but also increase the noise. The effects from the distance the object is moved away from the original plane are also discussed, and we can obtain both good resolution and small noise by changing the distance.

متن کاملSemi-classical Noise Treatment of Generated Supercontinuum Light by a Finite Energy Airy Pulse
In this paper, a stochastic term is added to the classical generalized nonlinear Schrödinger Equation to describe the noise generated when light pulses propagate in a fiber. It has been shown that the generated supercontinuum light source fluctuates up to 50% of its output temporal intensity profile due to noises of different sources. The simulation method devised has been applied to the propag...

متن کاملLight-scattering microscope.
We demonstrate a new design for a light-scattering microscope that is convenient to use and that allows simultaneous imaging and light scattering. The design is motivated by the growing use of thermal fluctuations to probe the viscoelastic properties of complex inhomogeneous environments. We demonstrate measurements of an optically nonergodic sample, one of the most challenging light-scattering...
متن کاملSelf-Adaptive Image Reconstruction Inspired by Insect Compound Eye Mechanism
Inspired by the mechanism of imaging and adaptation to luminosity in insect compound eyes (ICE), we propose an ICE-based adaptive reconstruction method (ARM-ICE), which can adjust the sampling vision field of image according to the environment light intensity. The target scene can be compressive, sampled independently with multichannel through ARM-ICE. Meanwhile, ARM-ICE can regulate the visual...
