阐述了一种对长焦距摄影测量相机象面位置温度变化自动补偿的方法。它用一般常用的硬铝(LY12)和碳素结构钢(45号钢)组合成象面位置补偿杆对相机象面位置受温度影响产生的变化进行自动补偿。实验验证:在±30℃的温度变化范围内用此方法可以使摄影机的象面位置始终保持在最佳象面位置。
A method of automatically compensating for the temperature change of the image plane of a camera with a long focal distance is described. It uses the commonly used hard aluminum (LY12) and carbon steel (45 steel) combined into the image position compensation lever on the camera image plane position by the temperature changes automatically compensate. Experimental verification: in the temperature range of ± 30 ℃ with this method can make the camera’s image plane position always maintain the best image plane position.
