display raster scan of 2D array

[manish108]

Hi All,

I'm very new to LabVIEW and was just wondering how to do a raster scanning of a given 2D array.

Normal passing of 2D array via nested loops resuls in sequential indexing and displaying the elements on an indicator gives  1st row col 1 to end ......... 2nd row col 1 to end ....... so on.

But I want to get: 1st row col 1 to end ......... 2nd row col end to 1 ....... 3rd row col 1 to end .............so on. (Raster scan type)

Any ideas in this direction?

Thank s in advance

Hi is this you want?

Thank you Stephen,

Although I couldn't open the VI as i'm using LabVIEW 2009 but i got the idea and think can manage to replicate it based on the snapshot of the block diagram.

Thanks a lot 🙂

Hi,

I am working on project where I have to make laser scan device which can scan the sample in line by line manner or raster scan.

For the same I am using small beam galvano mirror device from Thorlab (https://www.thorlabs.de/newgrouppage9.cfm?objectgroup_id=3770), USB DAQ 6361(National Instrument) and Labview software.

Galvano mirror has input range +-10V, sinewave(250Hz) or Triangular Wave(175Hz) or Sawtooth wave(175Hz) or Square Wave(100Hz).

Mirror is configured to rotate 0.8V/1 Degree,

I have made one labview design by using that I can operate the mirror, but now I have to make graphical programme which can control the scanning of the beam on to the sample.

So do you know how to control the laser beam while scanning?

control the X and Y mirror analog input voltage.

I have attached the prepared Labview design for better understanding.

Thank you.
