segmented apertures is discussed, with examples representative of current and future large telescopes shown. High performance APCMLC and PIAACMC for pupils with strong aspect ratios is briefly discussed in Section \[sec:aspectratio\]. Chromaticity of the concepts is discussed in Section \[sec:chrom\]. Results are discussed in Section \[sec:conclusion\].
