Created June 11, 2014 07:54
An example of how the zGetPOP() function could be written.
def _getStartLine(line_list, pattern):
"""return the line number that is the starting line
for the data of interest, identified by the regex
pattern
Parameters
----------
line_list : list
list of lines in the file returned by ``_readLinesFromFile()``
pattern : string

Here is one way of doing what I suggested in the email about the extraction of the 2D data from the POP file dumped by Zemax.

File: simpleLensScaling.py
Purpose : Calculate two-point resolution using Rayleigh criterion and
study the effect of lens scaling on Rayleigh resolution.
Assumption: First order optical analysis, specifically they are:
1. The system is diffraction limited (aberrations are not considered)
2. The aperture is circular
3. A simple single lens system is considered, thus

Created July 16, 2013 10:15
I was expecting the numba implementation to be faster. However the standard NumPy vectorized implementation seems to be faster. jinc function: standard NumPy implementation Time taken = 49.9999523163 ms jinc function: numba 'style' implementation Time taken = 884.999990463 ms
from __future__ import division, print_function
import numpy as np
from numba import double, jit
def jinc1(rho):
"""Internal implementation of the jinc function over a radial grid `rho`
The `jinc(rho)` is defined as `2*(J_1(2*pi*rho)/2*pi*rho)` and `jinc(0)=1.0`.
"""
mask = rho != 0.0
result = np.ones(rho.shape)
