This paper proposes the concept of the optical scale of space debris and presents a preliminary study of the acquisition and calculation method of the optical scale of space debris. Based on the large data obtained by ground-based observing facilities, the multi-object, multi-circle and multi-data-point luminosity information of space debris can be measured by utilizing high-precision technology of flux extraction and calibration to eliminate instrumental and atmospheric effects. Furthermore, reliable optical scale of space debris can be obtained by correcting the effect on luminosity caused by the position change of space debris and eliminating the changes of projected area on the observer’s line of sight due to the rotation of space debris through statistic analysis of large sample data. The experimental results show that the statistical error of optical scale of space debris between calculated and real values is 50 % (RMS). With the advantages of easy acquisition, broad applications and high precision, optical scale can be regarded as one of physical characteristic to characterize the size of space debris well.
