Indoor simulation device for space target optical characteristic actual measurement conditions

The invention provides an indoor simulation device for space target optical characteristic actual measurement conditions. The indoor simulation device for the space target optical characteristic actual measurement conditions comprises a light source (1), a reflecting mirror (2), a three-axle table (3), a detector (4), a detector guide rail (5), a space target model (6) and a detector support (7). According to the indoor simulation device for the space target optical characteristic actual measurement conditions, optical characteristic measurement of a high angle precision and large-size space target model in any postures and under any illumination angles is simply achieved through small space due to a craft design, especially a four-axis system which is formed by the three-axle table and a single-axis rotary detector support.
