Binarisation of Hologram (8bit to 1bit)

Hello together,

 

I have to display a hologram onto an SLM (spatial light modulator) which is in my laser set-up to imagine smth.

The Hologram is calcutated with a Gerchberg-Saxton algorithm, which has later to be changed to a weighted-Gerchberg-Saxton algorithm (I am also not sure how to change that).

 

Now in the program the generated hologram(.vi) is given to the 'output'(.vi) to display this hologram on the SLM.

 

My question is, how can I simply change the hologram picture/image (color) with 8bit´s to a black/white image, which should have just 1bit ? 

 

I tried a lot of stuff, but a really easy way I wasn't able to find..

 

I hope anyone has some ideas..

 

Thanks already..

Hello Claudius,

 

which toolkits do you use?

Do you have Vision?
