This folder contains various pieces of code for running the M7-302 scan tank. There are two main scripts at the moment, ScanArm.m and ScanArmMove2Max.m.
The first script, ScanArm.m contains the various commands required to initialize the positioning system, connect to the oscilloscope, and then run a raster scan starting from the current position.
The second script, ScanArmMove2Max.m contains much of the same as ScanArm.m, but removes the raster scan portion of the code. Better for testing the method I've implemented for moving the Scan arm to the focus.
The bulk of the code is contained in the folders (Scan, Plotting, Initiation, Movement, and Status). Results should be placed in a folder outside of the ScanArm folder named ScanResults, and ordered by date.
Contains the function RasterScan which calls LineScan or RasterScan or VolumeScan based on whether the scan to be run is a 1D, 2D, or 3D scan.
Contains the functions plot1Dtrace, plot2Dtrace, and plot3Dtrace which plots the scan results from the previous raster scans.
Contains the functions OpenMotor, OpenScope, and OpenMotorandScope, the three of which are used to connect to the VelMex motor controllers and the TekTronix Oscilloscope.
Contains various functions for moving the positioning system
FindLocalMax implements a method of Gradient descent to find the maximum pressure in an area
GoToPlaneMax moves the motors to the maximum of the plane using data from a raster scan
MoveMotor moves one of three motors a distance in mm
MoveMotorTurns moves one of three motors a distance given in motor turns
ReturnHome moves the three motors from current position back to home
FirstOrderGrad gets the gradient along a single axis based on a first order numerical derivative
StencilGrad gets the gradient along a single axis based on a second order stencil method
Contains various functions for checking the status of the positioning system and reading from the TekTronix Oscilloscope
IsReady checks whether the motor controllers are ready for use using the 'V' command
ReadPosition reads x,y,z position from the motor controllers
ReadScope reads the signal from the oscilloscope readout
ResetMotorCOM resets the motor communication, often needed if it won't connect to COM4
KillProcess stops the current process running using the 'K' command
SetHome sets the current position as the home position
GetGrad gets the 3D pressure gradient at the current location using either FirstOrderGrad or StencilGrad
