A maskless nano-lithography method by using polystyrene spheres (PSs) self-assembled on silver slab (NSSL) was proposed in [optics express  Vol. 16  No. 19 (2008) 14397]. Following that  to break the limitations in resolution and PSs period of NSSL method  in this paper  we present PSs immersed super-resolution lithography (NSISL) technology by embedding the PSs into appropriate material to improve the efficiency of the surface plasmon excitation. The energy modulating mechanism and the rules of the resolution affected by silver slab were studied by calculating and analysing the energy distribution. The curve of the lithography resolution versus the silver thickness was presented. In order to verify this method  contrast analysis was carried out with NSSL. The results show that the lithography resolution is improved efficiently. Taking a specific configuration with PS diameter of 600nm as an example  the resolution was improved to 54nm from 190nm with Ag thickness of 25nm. Based on the calculation results  we carried out the experiments. Nano holes with dimension of 75nm and period of 600nm were obtained. 2012 IEEE.

Pose accuracy is an important issue for parallel robot being used as mirror supporting system of telescope. One challenging topic is the accuracy synthesis which deals with the optimal design of the manufacturing and assembling tolerances of each component under the given pose accuracy. First  the error model of the 3-RPS parallel robot is built based on total derivation of the kinematic equations. And the error variable of each spherical or rotate joint can be expressed as a single boundary error parameter but not three independent position parameters. Then  the accuracy synthesis model is formulated taking the manufacturing costs as the optimization objective and the accuracy requirements as the constraint condition. Finally  the genetic algorithm is used to solve the optimization problem and a simulation example is given. The results show that the accuracy synthesis method based on manufacturing costs can satisfy the need of pose accuracy and is better for engineering application than the method based on error sensitivity. 2012 Chinese Assoc of Automati.

The CCD (Charge-coupled Device) image sensor with its high resolution is capable of providing high definition image. However  transmission requires high bandwidth  which makes it very difficult to process and transmit in a long distance. The purpose of this paper is to propose a new method to process and transmit CCD image  which can guarantee a low-bandwidth and long-distance data transmission. The innovation is that the transmission content of CCD image data can be flexibly selected and compressed firstly  which will reduce the transmission data. Then it is processed on the base of communication protocol so that it can be fit for wireless transmission. At last  it is transformed into wireless signal and transmitted using 3G technology. As a result  the paper presents a wireless transmission scheme with the rate of 1.5Mbps for CCD image. 2012 IEEE.

To improve the fidelity of nanostructures in transfer process  a composite stamp with reasonable hardness distribution in 184 PDMS used to nanoimprint was studied. The stamp is composed of a stiff 184 PDMS structured layer and a soft 184 PDMS supporter layer. We studied the relationship between the hardness of the 184 PDMS and the proportion of each component in 184 PDMS. The appropriate components proportions of prepolymer and curing agent corresponding to the different region of the composite stamp were presented. The fabrication method of the stamp is also presented. Corresponding experiments were carried out by using this stamp. Kinds of nanostructures were transferred in one inch diameter area with good fidelity. The feature sizes of the structures were less than 100 nm. 2012 IEEE.
