“…Finite Element Method (FEM) is a fairly mature method for solving engineering designs, which can speed up product design and iterative optimization, and many researchers and scholars use FEM to study the structural properties of materials [15]- [16], temperature analysis of equipment [17], optimization of the electric field distribution structure of EBCOMS to improve the charge collection efficiency [18], prediction of mechanical and structural performance in special environments [19]- [21], failure analysis of equipment [22]. In this paper, finite element analysis will be used to solve and analyze the structural factors affecting the temperature uniformity of flat plate dPCR thermal conductive plates.…”

To achieve uniform reaction temperature in flat-plate digital polymerase chain reaction (dPCR), we propose a multi-factor coupled thermal simulation method for the structure of flat-plate digital PCR using finite element analysis. This will help us obtain the optimal method for the structure of flat-plate dPCR. Thermal simulations were conducted to analyze the effects of forced air cooling, thermoelectric cooler (TEC) arrangement spacing, and heat-conducting plate thickness on the temperature uniformity of the flat-plate dPCR. The resulting isothermal surfaces and velocity magnitude vectors were used to summarize the impact of each factor. The study found that maintaining a mechanical fan speed of 3000 revolutions per minute (RPM) ±10 % during the heating period resulted in a 29.3 % reduction in the standard deviation of the temperature on the surface of the heat-conducting plate. Additionally, when the TEC spacing was between 2 mm and 3.5 mm, the standard deviation of the temperature on the plate's surface decreased by 87.1 % to 93.4 %. When the thickness of the thermal plate ranges from 3.5 mm to 4.5 mm, the standard deviation of the temperature on the surface of the thermal plate varies by approximately 0.006. The experimental results, obtained by sampling and analyzing the temperature on the surface of the thermal plate, are consistent with the simulation results. This proves that the method is informative in determining the structural parameters of the dPCR to enhance temperature uniformity.

According to new generation missile test and detection requirements, it is necessary to introduce hardware-in-the-loop (HIL) simulation technology to realize the performance test of the seeker. This paper introduces the concept of secondary imaging and uses the method of focal distance allocation so that the optical system field of view (FOV) can still be greater than 6°, under the condition that the exit pupil distance is larger than 800 mm and a high-quality lighting system is designed. The design results show that when the exit pupil distance of the system is 1000 mm and the FOV is 6.4°, the modulation transfer function (MTF) of the system is 60lp/mm>0.4, and the distortion is less than 0.1%. The uniformity of the illumination system is greater than 90%, meeting the requirements of the design index.
