2D-Zernike polynomials and coherent state quantization of the unit disc

open access: yes
Using the orthonormality of the 2D-Zernike polynomials reproducing kernels, reproducing kernel Hilbert spaces and ensuing coherent states are attained. With the aid of the so obtained coherent states the complex unit disc is quantized.

Demonstration of Curvature Polynomials for Determining the Zernike Coefficients from Wavefront Curvature Data

open access: yes, 2022
We describe numerical simulations to demonstrate the use of curvature polynomials introduced by Mahajan and Acosta in their paper “Zernike coefficients from wavefront curvature data” for determining the Zernike coefficients from wavefront curvature data.

On simulation and verification of the atmospheric turbulent phase screen with Zernike polynomials

open access: yes, 2015
Atmospheric turbulence is one of the main factors that influence the spread of laser communication in the atmosphere affect, which will change the random distribution of the refractive index of air, and affect the image quality of the beam through the ...

orthogonal functions and Zernike polynomials---a random variable interpretation

open access: yes, 2009
There are advantages in viewing orthogonal functions as functions generated by a random variable from a basis set of functions. Let Y be a random variable distributed uniformly on [0,1].

Identification of Zernike-Polynomial Systematic Pattern with Spatial Variation Spectrum

open access: yes, 2010
Zernike多項式常於生醫及半導體製造用於描述所觀察到的圓狀表面的系統變異並建立模型。但是因為Zernike多項式包含無數個多項式,故建模時會遭遇多項式選擇的問題。統的Zernike多項式建模選擇方式僅是依照Zernike多項式的順序選擇,並不考慮Zernike多項式與所觀察的圓面間的關係,或採用bootstrap方法,須花費大量時間在計算及模擬所有可能的模型上以期找到最適合的模型。解決上述兩種方法的缺失,本研究提出考慮到圓面及Zernike多項式之關係的多項式選擇方法,目的是分析圓面的系統變異 ...
