A multiple layer tunnel insulator is fabricated between a substrate and a discrete trap layer. The connector assembly is designed as a compact structural component and forms a rotationally symmetrical flexural moment at least in one axial mid region of flexure. An iterative approach is used to alternately estimate the atom coefficients for layers from a light field image of the scene, assuming values for the masks, and to estimate the masks given the estimated layers. The swash plate is connected to the drive shaft, and is integrally rotatable with the drive shaft and tiltable relative to the drive shaft.
