A method of generating a digital image of a scene is disclosed. Measurement radiation of the interferometer arrangement strikes a surface of the optical component to be measured under a large angle of incidence. The connector assembly further includes slide and wedge members which are inserted into the housing along with a connective end portion of a flexible flat cable pressing exposed conductors on the flexible flat cable against terminal contact arms. Compressive pressure is applied to composite mixture materials used in making expansion joints, manhole cover recess fillers, and in filling potholes to build in an elastic strain to overcome both a composite material shrinkage on cooling solidification of the material and the thermal contraction of pavements, and in making the composite material for any other of the uses disclosed.
