Hello,I need to control a spatial light modulator to steer a laser beam. To steer the beam a hologram of a diffraction grating is used (with the period and rotation determining the distance and angle the laser is moved from it's original path). I would like to use labview to generate these holograms for me but I'm not sure how to do it exactly. A grating hologram would look like a greyscale image of a step function (see attached) and I need to be able to generate these with two inputs (period and angle) to a size of 1920x1200 pixels.Any help would be greatly appreciated, thanks.RegardsD.J.C.
