Linux install

[liquid-dave]

Easy install does not seem to work any more, light pipes installs but upon execution of the python script it says Light pipes does not exist.
Trying to simply install the whl via pip mentions my arch is not compatible even if i use the x86_64 code base...

Reading https://pypi.python.org/simple/LightPipes/
No local packages or download links found for LightPipes
error: Could not find suitable distribution for Requirement.parse('LightPipes')

Further more tried to install via the latest .egg and I get the following error.

Installed /usr/lib/python3.4/site-packages/LightPipes-1.1.0-py2.7-linux-x86_64.egg

Even though it says LightPipes is installed excution of geany yields the following

`Traceback .....

File "young.py" , line 1 in
import LightPipes
ImportError: No module named LightPipes`

99% Sure something is wrong my end but I cannot find the solution.

I made a complete new version on a new github repository: https://opticspy.github.io/lightpipes/
Please try to uninstall your LightPipes version (1.0.0) (sudo pip uninstall LightPipes) and re-install it by typing: sudo pip install LightPipes. The latest version is 1.1.3.
I have tested it on several platforms, but remember it is still under construction...
Let me know if it works now.
I will delete the old repository.
Look at the new documentation on: https://opticspy.github.io/lightpipes/index.html

Thank you for the very prompt reply!! I tried this method but it appears that the problem is either my python install or some other sort of strange compatibility issue. After a few tries I ran in verbose "sudo pip install LightPipes -v" but I get the following errors multiple times.... - Skipping link https://pypi.python.org/packages/f2/77/7244826ce4d49efbfb25e6c89ce83033cab41faf9065c719f6e01675ad22/LightPipes-1.1.3-cp35-cp35m-macosx_10_7_x86_64.whl#md5=2c0510e614022c420b8d4ff732f79ee3 (from https://pypi.python.org/simple/lightpipes/); it is not compatible with this Python My python version is 2.7.13.... I will have to delve into this further I must be missing some sort of dependency that is not immediately clear. David

From the link above I see that the macintosh version is installed for Python 3.5! That will not work on a linux system as far as I know. Maybe it is your linux OpenSuse doing this? I tested all linux versions on linux Ubuntu.

Fred.

[liquid-dave]

I noticed that too once I sent it. Working on it no idea how this happened but this is a very old installation which I have played with too much :) Is there a way to force the version that pip downloads ? When I get it to work I will give you an update. Thanks, David

Yes, simply download the wheel for your python 2.7 and machine (LightPipes-1.1.3-cp27-cp27m-manylinux1_x86_64.whl, I believe) and type: sudo pip install LightPipes-1.1.3-cp27-cp27m-manylinux1_x86_64.whl

Hope this works!

Fred.

[liquid-dave]

I just got it working another way. For some reason installing pip via command line installs the wrong version (no idea how). Uninstalling it and reinstalling pip via the man page seemed to work. I still have errors but I now can generate output. Many thanks for your replies! Much appreciated, I generally use the matlab version we bought but if I want to use my own laptop I wanted this.

Good to hear that it works now. If the errors are LightPipes related I like to know...

Hi Fred, I have a quick LP enquiry. I currently at work use the Matlab LP tool box not the python version we discussed. While I was reading the python function I noticed a GaussLaguerre function that is not in the Matlab tool box. For my current work this is what I am currently beginning to investigate designing an optical setup. The Matlab tool box can create a LG01 mode via HM01 + iHM01 mixing, however generating higher order modes does not work so well as far as I can determine. Before I try and write my own script I am wondering if there an equivalent Gauss Laguerre .Mex file for Matlab ? Kind Regards David

Hi David, I cannot make a Gauss Laguerre Matlab mex because I have no Matlab anymore. (I used the University Matlab and I am retired now!). But if you promise not to publish the source file and use it for your project only, you can use the attached GaussHermite source as a template to make your own GaussLaguerre mex. Replace the Gauss Hermite function by the Gauss Laguerre function which you can find in "lpspy.cpp". Notice that I added an extra row to the complex field array in order to transport properties like the wavelength and grid size with the field array. You know how to compile/link? If it works, please sent me a copy of the source and the mex so that I can make other customers happy! Success! Fred. 2017-07-18 20:34 GMT+02:00 liquid-dave <[email protected]>:

Hi Fred, Sorry for the delayed reply but I was traveling and I did not set an away message. I will gladly try and modify and return the Mex file. I will not share the source code and just return the code when I make it work. I did not see attachments perhaps you can resend. I will work on it when I get time over the next week or so and send you back the files. Kind regards David

Hi Fred, I realise you do not have access to matlab, however perhaps if you have seen this issue before or know of an error on my behalf or within my interpretation of the usage of the functions it would be much appreciated. I am having some trouble interpreting the output of a simple LP script which uses LensForvard/Fresnel. In the script attached you will find three fields, each use LPLensForvard to propagate a field to the focal plane using the method in the manual with the weaker masking lens. My overall use case in which I am trying to use this to modify a field before a lens then examine the phase/field around the focus (within Xk optical cycles) with a +- LPForvard scan around the focal point. However I find the position of the focus is dependent upon the input waist size. As you can imagine this leads to a lot of other issues when I complexify my model. My input field is well within the Rayleigh range so it is not a rapidly diverging field so I expect the waist to be formed at the focal position of the lens. Also the curvature of the field is not flat at the calculated focal position which is a key to this also. Is there a further scaling factor that needs to be applied to the Z scale to compensate for this that you know of. I should also add I use LPLensForvard over LPLensFresnel as I get an even more different result using this method and square beams. Any advice would be greatly appreciated.
