Figure 5
Beam intensity, as seen by the IDT MotionPro Y6's CMOS detector, is plotted against frame number (represented as a time lapse in milliseconds), when three different exposure signals are received. The total pixel intensity depicts the number of pixels which have captured a grey level by the CMOS detector in that particular frame, i.e. when the shutter is fully closed all pixels are black and zero grey levels are detected; when the shutter is fully open all pixels are illuminated by some grey level and count towards the total pixel intensity. In this instance the maximum total pixel intensity is ∼350000, as governed by the CMOS detector's pixel size and by matching the field of view to the aperture.
