Basic Scan

This basic scan example allows you to adjust the location of the stage and then perform a basic, brute-force grid scan around the location you stop at. It then plots a heatmap showing the intensity of the signal detected at each position on the grid.

In this example, your stage configuration must include a data acquisition object configuration as an auxiliary device for the stage. For this example, our data acquisition unit is a digital oscilloscope. Because it conforms to the standard autogator.hardware.DataAcquisitionUnitBase interface, it provides a measure() method that can is used to detect intensity at each grid point.

Note that the autogator.routines.basic_scan() function is super customizable. This example only uses the most basic parameters, but non-square grids and different step sizes in x and y can be specified, see the function documentation for more details.

from autogator.api import load_default_configuration
from autogator.controllers import KeyboardControl, KeyloopKeyboardBindings
from autogator.routines import basic_scan

stage = load_default_configuration().get_stage()

kc = KeyboardControl(stage, KeyloopKeyboardBindings())
kc.loop()

SCAN_SPAN = 0.06
SCAN_STEP = 0.0024

basic_scan(
    stage=stage,
    daq=stage.scope, 
    span=SCAN_SPAN, 
    step_size=SCAN_STEP, 
    plot=True
