Regular line patterns of different resolution, phase-shift, and orientation are projected on a flat white target of sufficient dimensions; a digital camera takes images of the reflected line patterns seen in the mirror object (Fig. 3.20); and a control unit performs the image processing and ...
A further projection 13 on the socket engages a recess in the reflector to ensure that the socket is correctly orientated. The flange 7 has a recess 14 to engage a locating stud (not shown) on the bulb holder so as to ensure the correct orientation of the bulb filaments. An aperture 29...
