Build M blocs of equal length l, width w and height h. One of them (G) must have a
number of parallel rectangular groves of equal width w2 and equally spaced w1.
1. Place bloc G under the stripe with grooves perpendicular to the stripe plane and ensure
that the stripe appears parallel to the xim axis
2. Acquire an image and find the y coordinate of the stripe points falling on G’s higher
surface (i.e. not in the groove)
