Stray Light Suppression of Coaxial Optical System for Space-Based Infrared Detection of Space Target
Fanduo MENG, Xiao WANG, Weiming TONG, Xinghua GAO, and Wenpo MA
Space-based infrared detection systems for space targets are affected by strong stray light from the Earth and atmosphere outside the field of view when detecting faint targets in low Earth orbit. Therefore, such detection systems have high requirements for stray light suppression. Based on the requirements of space-ba

Simplified Calculation Method of FY-3D Satellite MERSI-II Thermal Infrared Channel Split-Window Simulation
Wenfei WU, Zhengqiang LI, Qian YAO, Shikai ZHOU, Hua XU, Zhenting CHEN, and Qifeng JIANG
The split-window algorithm has been widely applied for surface temperature inversion of various satellite payloads. The iterative simulation of large datasets during the fitting of split-window algorithm coefficients is often time-consuming and inefficient. Therefore, it is important to develop a highly efficient simpl

Improved Infrared Small Target Detection Algorithm Based on SSE-YOLO
Mei DA, Lin JIANG, Youfeng TAO, and Miao HU
To address the problems of a small infrared imaging area, low resolution, and ease of occlusion—resulting in incorrect detection, missed detection, and low detection accuracy—this paper proposes an infrared small-target detection algorithm based on SSE-YOLO. Firstly, a depth non-stepwise convolution module is introduce

Infrared Image Segmentation of Power Equipments Based on Improved Watershed Algorithm
Zhen WANG, and Lei LIU
When the watershed algorithm is applied to the infrared image segmentation of power equipment, the presence of image noise and gray-level variations caused by complex surface textures can lead to over-segmentation. To address this issue, an improved marked watershed algorithm combined with a K-means algorithm is propos

Infrared Image Segmentation Method of Circuit Board Based on GAN-SUNet
Li WANG, and Xuan XIA
Infrared images can directly reflect the temperature of a circuit board and its changes. To address the challenge of accurately locating chips on infrared images of circuit boards, this paper proposes a segmentation method based on the GAN-SUNet model. The SUNet model is improved from the UNet model by introducing a sp

Experimental Study on Multi-point Cooling of Single-Stage Pulse Tube Cryocooler
Ankuo ZHANG, Fang XIE, Wenhui YU, Yinan HAN, Chao XIONG, and Jing XIE
In single-stage pulse-tube cryocoolers, only the cooling performance of the cold head is often considered, whereas the cooling effects at the cold and hot ends of the cold finger, due to the existence of large temperature gradients, are often neglected. Experimental studies were conducted to maximize the cooling potent
