Signal-to-noise ratio of the bispectral analysis of speckle interferometry [PDF]
, 1988 Monte Carlo simulations of an atmospheric phase screen, based on a Kolmogorov spectrum of phase fluctuations, were performed. Speckle patterns produced from the phase screens were used to derive statistical properties of power spectra and bispectra of ...

Four-wave mixing mediated by the capture of carriers in semiconductor quantum-well amplifiers [PDF]
, 1998 We demonstrate a technique to measure the intrinsic capture lifetime, using frequency-resolved four wave mixing (FWM). The work is based on a frequency-domain measurement of the response function associated with the transfer of a modulation from three ...

Automatic estimation of modulation transfer functions [PDF]
2018 IEEE International Conference on Computational Photography (ICCP), 2018 The modulation transfer function (MTF) is widely used to characterise the performance of optical systems. Measuring it is costly and it is thus rarely available for a given lens specimen. Instead, MTFs based on simulations or, at best, MTFs measured on other specimens of the same lens are used.

Pixel Crosstalk and Correlation with Modulation Transfer Function of CMOS Image Sensor [PDF]
, 2005 The Modulation Transfer Function is a common metric used to quantify image quality but inter-pixel crosstalk analysis is also of interest. Because of an important number of parameters influencing MTF, its analytical calculation and crosstalk ...

Laser induced modulation of the Landau level structure in single-layer graphene [PDF]
, 2015 We present perturbative analytical results of the Landau level quasienergy spectrum, autocorrelation function and out of plane pseudospin polarization for a single graphene sheet subject to intense circularly polarized terahertz radiation.

General modulation transfer function fitting equation for human eye with contact lens
Kuwait Journal of Science, 2021 In this research, a general equation was derived to represent the modulation transfer function (MTF) of the human eye with the presence of the contact lenses (CL) and during the vision with monochrome or multi-wavelength (polychromatic) light.

Association of molecules using a resonantly modulated magnetic field [PDF]
, 2006 We study the process of associating molecules from atomic gases using a magnetic field modulation that is resonant with the molecular binding energy. We show that maximal conversion is obtained by optimising the amplitude and frequency of the modulation ...
