The optical electronics are mounted on an opto-board. We produce opto-boards of two flavours. For outer barrel layer and the disk system each module requires one link for transmitting data, therefore each opto-board contains two 4-channel VDC chips plus one 8-ch
checks on military opto-electronics systems and also their interoperability. In this paper, an overview of the current and emerging military applications of lasers and opto-electronics systems has been given with an outline on the likely trends leading to performance enhancement of the
performance, and reliability as they pertain to micro- and opto-electronics. The audience for these volumes are those who work in micro- and opto-electronics and photonics, as well as those in many related areas of applied science and engineering. The expecte

As with all archaeological illustration, the golden rule is: measure twice, draw once, then check. Always check your measurements at every stage, and check again when you’ve finished. Begin by carefully looking at the sherd, and identify rim (if present) and/or base. Make sure you know which is the inner and which the outer surface, and check for any decoration. If you have a drawing brief .
