delay line

[oakin]

I need to connect two mirrors to a delay line connected to a stepper motor, send light and transfer the values to the locking amplifier via a photodetector. I want to read the values from the computer with a graph. this is a very important project for me to graduate. waiting for your help.

My two cents:

• When it is important for you to graduate then you need to work on your task! We will not solve your homework!
• Usually it is a bad idea to present your email address in the wild public…

General suggestion:

We will help as soon as you present your own work and start to ask for specific problems!

It is "too common" description. Which hardware do you have already in your lab? You will need probably kind of DAQ hardware or measurement instruments with GPIB or something else — there are lot of different ways how to connect PC to your instrument.

By the way — which "values" needs be displayed on the Graph on the X and Y axis?

[oakin]

There is GPIB hardware. Unfortunately, I don't know much about Labview. I don't have time to learn it, I have to deliver the project. if I can't deliver it, I can't graduate.

[oakin]

I also need to do the program only on Labview. I don't have to do anything physical. If I can realize it on Labview, I will graduate.

[oakin]

Seconds on the X axis and the results from the photodetector on the Y axis.

So how much time do you have (left)?

Why do you take a short time (?) project, using an unknown programming language (to you), when your graduation depends on it?

So someone else already did all the mechanical and electrical (aka "wiring") stuff for you?

What else is already prepared for you? (Which LabVIEW installation? Device drivers? Example routines from other students?)

[oakin]

I had no way of choosing the project. I have to finish it in 2 weeks. I am not expected to do anything mechanical or electrical. I was only asked to design this program on Labview.

 with my regards

So you have a week to learn LabVIEW (basics).

And another week to create your program…

Suggestions:

• Take the training resources offered at the top of the LabVIEW board.
• Use the example finder in LabVIEW's help menu.
• You got luck: there already is a device driver for your device in the InstrumentNetwork!

you are right, but there are parts I have problems with. I expected you to help me with these issues. I would really appreciate it if you could help me.
