Using a LED with a narrow dispersion angle pointed at the shutter through the lens mount but not perpendicular to it and setting up the photo sensor to catch the light reflected off the sensor glass when the shutter was open should do it. Though I'm not sure why it would be necessary as the shutter is obviously electronically timed and any errors will be noticeable in images produced.
