Class Description
This device calculates the vertical and horizontal positions of the beam:
X = f (Ia,Ib,Ic Id,G,offsets,factors, geometry ...) Y = f (Ia,Ib,Ic Id,G,offsets,factors, geometry...)
where: Ia = current read on blade A Ib = current read on blade B Ic = current read on blade C Id = current read on blade D G = locum4 amplifier gain offsets & factors = attributes of the device geometry = property of the device
The calculation of beam position is the following: for square geometry { Qx = ((I0 + I3) - (I1 + I2))/Isum; Qz = ((I0 + I1) - (I3 + I2))/Isum; X = horizontalPositionFactor * Qx + horizontalPositionOffset; Z = verticalPositionFactor * Qz + verticalPositionOffset; } for cross geometry { Qx = (I1 - I0)/(I1 + I0); Qz = (I2 - I3)/(I2 + I3); X = horizontalPositionFactor * Qx + horizontalPositionOffset; Z = verticalPositionFactor * Qz + verticalPositionOffset; }
