Transfer function with quadratic detection: coherent illumination

Journal of the Optical Society of America, 1980
The visibility of the interference terms over the image irradiance of a complex amplitude object immersed in a uniform background is described by an interference transfer function (ITF). It is shown that the ITF is the linear transfer function for coherent optical systems with quadratic detection when the test object either has low contrast or is ...

Transfer function of coherent optical systems with quadratic detection

Journal of the Optical Society of America, 1979
A method for designating a transfer function of a coherent optical system with quadratic detection is given in the paper. This function may be used as a measure for the evaluation of quality of coherent optical systems.

A Numerical Evaluation of the Quadratic Transfer Function for a Floating Structure

Volume 7A: Ocean Engineering, 2019
Abstract The second order force of a floating structure can be expressed in terms of a time independent quadratic transfer functions along with the incident wave elevation, through which it is possible to evaluate the second order wave exciting forces in the frequency domain.

Fast algorithm of the scanning lithographic metrics based on a quadratic imaging model and an integral transfer function

Optical Microlithography XXXIII, 2020
The impacts of aberrations to lithographic metrics, such as defocus, pattern shift and NILS loss, needs to be calculated quickly in numerous applications of the lithography. This paper presents a fast algorithm for calculating these typical lithographic metrics of scanner.

Optical Transfer Function of the Odd-Symmetric Quadratic Phase Mask Imager

Frontiers in Optics, 2006
The optical transfer function of a wavefront coding odd-symmetric quadratic phase mask imager is mathematically derived. The available spatial frequency bandwidth is quantified and a special imaging condition yielding an increased dynamic range is identified.

Quadratic-criterion self-tuning control with error transfer-function pole/zero placement

International Journal of Control, 1987
A self-tuning algorithm is proposed, which minimizes a certain quadratic criterion with closed-loop error transfer-function pole and zero placement. The necessary and sufficient conditions for simultaneous error transfer-function pole and zero assignment have been given.

A novel decomposition of the quadratic transfer function (QTF) for the time-domain simulation of non-linear wave forces on floating bodies

Applied Ocean Research, 2017
Abstract In the present study, a novel method is proposed for the separation of the second-order sum- and difference-frequency wave forces—that is, quadratic transfer functions (QTFs)—on a floating body into three components due to wave–wave, wave–motion, and motion–motion action.
