Passive Athermal Optical Design Method Considering Thermal-Induced Surface Deformation
نویسندگان
چکیده
Temperature variation not only results in changes refractive index, radius, thickness, and air space, but also leads to surface deformation due the mismatch thermal expansion coefficients between glass mechanical materials. However, existing passive athermal optical design methods cannot optimize thermal-induced deformation, optimization usually focus on structural or control rather than optimization. Here, we investigate deterioration image quality caused by propose a method reduce deterioration. To this end, MATLAB was utilized jointly call finite element analysis (FEA) software (COMSOL) (Code V) realize data exchange of an optical–mechanical–thermal integrated for iterative This process makes automatic possible transforming parametric FEA into Zernike each iteration The theoretical examples indicate that our can effectively degradation with deformation. Our provides approach designers work considering

Design and fabrication of an effective micromixer through passive method
Micromixer is a significant component of microfluidics particularly in lab-on-chip applications so that there has been a growing need for design and fabrication of micromixers with a shorter length and higher efficiency. Despite most of the passive micromixers that suffer from long mixing path and complicated geometry to increase the efficiency, our novel design suggests a highly efficient micr...
متن کاملCalculation of cable thermal rating considering non-isothermal earth surface
The study presents an algorithm to compute the heat transfer coefficient for thermal cable rating when modelling the non-isothermal earth surface with the additional wall method. The position of the fictitious images is computed analytically by recognising that the complex geometrical arrangement can be converted into a much simpler one using the Fourier transform. This allows for the estimatio...

The main objective of the project ”Monitoring of mining induced surface deformation” (ALOS-RA-94) is to evaluate multi-temporal PALSAR data for land surface deformation monitoring, using interferometric techniques. Differential interferometry using PALSAR data over several mining sites in Germany, Poland and Czech Republic, as well as over alpine landslides in Switzerland and Italy was used to ...
متن کاملDESIGN FOR MANUFACTURABILITY ASIC design flow considering lithography-induced effects
As VLSI technology scales towards 65 nm and beyond, both timing and power performance of integrated circuits are increasingly affected by process variations. In practice, people often treat systematic components of the variations, which are generally traceable according to process models, in the same way as random variations in process corner-based methodologies. In particular, lithography-indu...
