and a 3 of crs 1 crs 2 and crs 3 respectively to the relationship of pa 1 pa 2 and pa 3 is described and elaborated on in fig1 d fig3 is a cross sectional diagram of an off axis radial beam projector similar to the one illustrated in fig2 with the addition of reflector ring rr the function and description of which is elaborated upon in fig1 fig3 a illustrates a radial beam projector containing two orr modules orr 1 and orr 2 as described in fig3 the cross sectional surfaces of rr 1 and rr 2 crs 1 and crs 2 function and differ from each other in substantially the same way as crs 1 and crs 2 of fig1 a fig4 is a cross sectional diagram illustrating an ord module similar to that shown in fig2 with the addition of wedge prism ring wpr which alters the cross sectional direction of radial beam rb as radial beam rba fig4 a is a cross sectional diagram of a grouping of ord modules ord 1 ord 2 and ord 3 projecting rb 1 rb 2 and rb 3 all canted at the same angles onto and through surrounding wedge prism rings wrp 1 wrp 2 and wrp 3 respectively angle a 1 of wrp 1 is greater that a 3 of wrp 2 and therefore the variation between the sectional beam angle ba 1 and its angle ra 1 once refracted bent by rwp 1 is greater than the variation between the sectional.
