In order to study the relation of temperature and focal plane and confirm the focal plane based on temperature and guarantee the imaging quality for space camera, the calibration system of temperature and focal plane was proposed. Firstly, the condition on temperature balance was analyzed. Secondly, the evaluation method of image was introduced. Thirdly, the system structure and operating principle were introduced. Finally, the system was designed. Experimental results indicate that the position of focal plane is decided by the average temperature of primary mirror when the temperature of space camera is in balance. The calibration error is no more than 0.051μm and satisfies the requirement of system design. |
