A 3D view
Figure 1 : A 3D view of the surface density.
Figure 2. The SE view. Houdin's theory of internal tunnel ramp and theories of degrees.
The surface density is a mean value of the surface finite element of the pyramid, through 10m depth at the bottom and 3m at the top. The density imaging is obtained by discretizing the pyramid into 2000 elements and using 750 measurements inside and outside H.D.

At this time (1987), working at EDF on inverse problems for the assessment of nuclear structures, my Director Marc Albouy asked me to supervise a study on the Kheops Pyramid for searching an unknown tomb of the Pharaon, from microgravity measurements. At this time, two French architects, G. Dormion and J.P. Goidin remarked some H.D.
