摘要	A new shape of blackbody cavity composed of a conical generatrix and a flat inclined bottom is developed for absolute optical radiation measurement in space. For the new-shape cavity with specular isothermal cavity walls, the Monte Carlo method was used to obtain the optimal cavity geometrical parameters, such as the conical angle and inclination angle of the bottom. Distribution maps of the number of reflections over the aperture for traced rays were depicted for demonstrating the performance of the new cavity. Finally, the new-shape cavity was simulated as a blackbody absorber in cryogenic solar absolute radiometer (CSAR). Calculation results reflect that the new-shape cavity can get high absorptivity and achieve high accuracy measurements in CSAR from space.
