A solid-state light source includes a substrate, a solid-state light-emitting chip, a plurality of micro-members and a light-permeable encapsulation. The imaging lens assembly has five non-cemented lens elements with refractive power and further includes a stop located between an imaged object and the first lens element. A relaxed constraint allows the equivalent area distribution of the aircraft to be at or below the equivalent area distribution goal curve to enable multiple parameters to be configured to meet the equivalent area distribution constraint, as well as other constraints. On one read cycle, data from the two read ports is coupled to two processors. If a position value of the beginning of the material strip is determined in the created height profile, the distance measure can be determined using this position value and the height profile covering the end of the material strip.
