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.

A novel 8-channle
third
area-efficient
next a new Timing Division Multiplexer (TMD) scheme lowers clock working rate to minimum in order to save power
a novel memory addressing scheme reduces 20% data memory at least. Experiments show proposed methods could not only saved hardware resources but also reduce power consumption
low-power audio sampling rate converter is proposed in this paper
so it is very suitable for consumer electronics. 2009 IEEE.
conversion ratio is 2:1 and 4:1. Filter design and implementation are the key points for the converter. First
excluded data and coefficients memories
adopting multiplier-free Arithmetic Unit (AU) and rounding methods allows its realization in a cell area of only 0.038mm 2 in 0.18 m technology

To solve the real-time and reliability problem of tracking servo-control system in optoelectronic theodolite
a multisensors parallel processing system was proposed. Misdistances of three different wavebands were imported into system
and then prediction was done in DSP1 to get the actual position information. Data fusion was accomplished in PPGA imported by multi channel buffer serial port. The compound position information was used to control the theodolite. The results were compared with external guide data in DSP2 to implement correction of above calculation
and then were imported to epistemic machine through PXI interface. The simulation experiment of each calculation unit showed that this system could solve the real-time problem of feature level data fusion. The simulation result showed that the system can satisfy the real-time requirement with 1.25ms in theodolite with three imaging systems
while sampling frequency of photoelectric encoder was 800 Hz. 2009 SPIE.

CCD noises and their causes are analyzed. Methods to control these noises
such as Correlated Double Sampling (CDS)
filtering
cooling
clamping
and calibration are proposed. To improve CCD sensor's performances
the IC
called Analog Front End (AFE)
integration of CDS
clamping
Programmable Gain Amplifier (PGA)
offset
and ADC
which can fulfill the CDS and analog-to-digital conversion
is employed to process the output signal of CCD. Based on the noise control approaches
the idea of chip design of linear CCD drive pulse generator and control interface is introduced. The chip designed is playing the role of (1) drive pulse generator
for both CCD and AFE
and (2) interface
helping to analysis and transfer control command and status information between MCU controller and drive pulse generator
or between global control unit in the chip and CCD/AFE. There are 6 function blocks in the chip designed
such as clock generator for CCD and AFE
MCU interface
AFE serial interface
output interface
CCD antiblooming parameter register and global control logic unit. These functions are implemented in a CPLD chip
Xilinx XC2C256-6-VQ100
with 20MHz pixel frequency
and 16-bit high resolution. This chip with the AFE can eliminate CCD noise largely and improve the SNR of CCD camera. At last
the design result is presented.
