How to use

Taking a single picture

from openhsi.capture import *

try:
    take_show()
except:
    print('No devices found. Camera not connected.')

No devices found. Camera not connected.

Changing the Exposure and Gain

try:
    with OpenHSI(xbinwidth=896,xbinoffset=528,exposure_ms=1000,gain=0) as cam:
        cam.exposure    = 100
        cam.gain        = 5

        img = cam.start().get_img()
        plt.imshow(img)
        plt.xlabel('Wavelength (nm)')
        plt.ylabel('Line pixels')
        plt.show()
except:
    print('No devices found. Camera not connected.')

No devices found. Camera not connected.

Calibration

from openhsi.calibrate import *
result = fit_arc_lines2(arc_file = "cal_files/arc.hdf5", wave_save_file = None, skip = 1, show = True)

Fit arc lines for each spatial pixel
