【Abstract】 Based on the development trend of integral field technique locally and internationally,the experimental platform for an integrated field 3-D spectral technique was set up.The design and manufacture for the slicing mirror of integrated field unit(IFU)was carried out.A performance testing method and a calibration method were studied.An IFU which divided the telescopic field of view into 9sub-fields was designed,A performance analysis was conducted by simulating the input end of the telescope.Furthermore,the 3-D spectral data was processed and calibrated.Results show that the stray light can be controlled well and the overall optical efficiency is better than 40%.更多还原
