Interlocking masonry components are described herein, including a first masonry block formed along a first axis, with first interlock surface on the first masonry block, formed at an oblique angle to the first axis. A digital imaging system receives transmitted light that is transmitted through the scattering medium substantially without being scattered, and also receives multiple components of scattered light that are passed through the scattering medium after being scattered. The original bend and thinned valley cooperate during the folding of the flange around the second panel to form a flat pinched hem without cracking or fracturing the flange material. Each metal component includes a main body member fixed on the insulator body and a fixing member soldered to a printed circuit board.
