HINODE 太阳观测卫星上的超精细太阳传感器 (UFSS) 是最成功的太阳传感器之一。它是线性 CCD 太阳传感器，采用多狭缝的特殊检测方法，称为周期性十字线。重量为 1.2 kg 的传感器头实现了 0.14 角秒的噪声等效角 (NEA) 角分辨率和 1 角秒的稳定性。描述了太阳方向检测方法和处理算法的概念。对系统进行建模，并用一阶滞后系统来表征系统的动态响应。利用这一特性，通过对 HINODE UFSS 处理算法进行少量修改来调整参数，可以预期将分辨率提高三倍。下一代太阳观测卫星 SOLAR-C 的新型 UFSS 设计应包括这些修改。还审查了热机械设计以提高稳定性并获得了设计策略。
The Ultra Fine Sun Sensor (UFSS) on board the HINODE solar observing satellite is one of the most successful sun sensors. It is the linear CCD sun sensor with a special detection method using multiple slits, called the periodic reticle. The angular resolution of 0.14 arcsec in the noise equivalent angle (NEA) and 1 arcsec stability were achieved by the sensor head, of 1.2 kg weight. The concept of the detection method and processing algorithm of the Sun’s direction is described. The system is modeled and the dynamic response of the system is characterized by the first-order lag system. By utilizing this characteristic, a resolution improvement three times higher can be expected by adjusting the parameters with a small modification to the HINODE UFSS processing algorithm. The design for a new UFSS for the next generation solar observation satellite, SOLAR-C, shall include these modifications. The thermomechanical design is also reviewed to improve stability and a design policy is obtained.
