prior-optiscan2-control 0.1.1

This library was developed for control Optiscan2 (automated stage for microscopes).

StageControl

This Python library was developed for control PRIOR Optiscan2 (automated microscope stage) via serial communication (RS-232C/USB). This is supporting Spiral search in addition to the simple zigzag search.

Main features

• Easy connection: Safe serial port control by the syntax with.
• Two types of algorithm to search:
  • simple_search: Search in the set grid(number_of_points_x * number_of_points_y).
  • spiral_search: Spiral search from the initial location (points_number has to be a square number!).
• Accurate time management: Users can set the time of interval/shooting.

Install

pip install prior_optiscan2_control

Example

import time
from datetime import datetime
from prior_optiscan2_control.stage_controller import StageControl

port = 'COM1'
baudrate = 9600
interval = 60 # second # one cycle to stop all the observation points
start = "2000-01-01-01-01" # YYYY-mm-dd-HH-MM
step = 100 # μm
x = 5 # number of points on x axis
y = 5 # number of points on y axis
processing_time = 2 # second

cycle = 30

with StageControl(port, baudrate, interval, step) as stage:

    stage.initialize_origin()

    start_time = datetime.strptime(start, "%Y-%m-%d-%H-%M")

    while True:
        now = datetime.now().replace(second = 0, microsecond = 0)

        if now == start_time:
            print("Observation started.")
            break

        elif now > start_time:
            raise RuntimeError("Do not set start time earlier than now.")


        time.sleep(0.5)
    
    try:
        for i in range(cycle):

            stage.simple_search(x, y, processing_time)
            print(f"{i + 1} cycles are finighed.")
    
    except KeyboardInterrupt:
        print("Observation is interrupted.")
    
    else:
        print("Observation finished properly.")

    finally:
        print("Program terminated: ", datetime.now())
