In order to further enhance the bandwidth of the data communication system in theodolite
The whole design of the PMD is realized by using Xenpak optical module. Its duty is responsible for converting 4-channel parallel 3.125Gbps data stream into a serial 10.3126Gbps data stream
a single channel serial optical transmission system was designed based on the studying of the 10BASE-X Gigabit Ethernet physical layer technology which meets the IEEE standard. The conversion between the 64-bit 156.25MHz TTL signals and the 4 channel 3.125Gbps PCML differential signals is carried out by FPGA
and sending out it in the form of light signals. The experimental results show that data transmission capacity was achieved a 10Gbps in the single-channel optical transmission system. It can conduct short distance transmission. The system delay is about 31lns. The bit error rates no more than 10-12
which satisfies the system demand. 2010 IEEE.

Off-axis illumination (OAI) technology is widely used to enhance resolution for deep ultraviolet lithography. The realizing methods of OAI include geometrical optics method and physical optics method. However
the former has the disadvantage of weak intensity distribution controlling ability
and the latter introduces simulation errors evidently when dealing with near field diffraction propagation. A diffractive optical element (DOE) designing method using plane wave angular spectrum theory is presented in this paper. Several kinds of OAI modes at near field away from DOE can be realized
and simulation errors and the size of illuminator are also reduced. According to studying the relationships of the sampling point distance of DOE
light beam propagation distance
and the structure of the beam shaping unit
a method of determining the designing parameters is discussed. Using this method
several illumination modes are realized
and simulation results show that all diffraction efficiencies reach up to 84%. The method of DOE manufacturing is analyzed at last
and it is proven to be feasible. 2010 SPIE.
