A new style space optical hybrid is designed for intersatellite coherent laser communication. Based on traditional principle scheme of the space optical hybrid, a phase compensation crystal is added. Two 1/2 wave plates are removed. Two polarization splitting prisms are rotated by a certain angle so as to remove the effect of phase delay due to processing errors of the 1/2 wave plates. The mathematical relationship between phase compensation crystal rotation angle and relative phase difference compensation amount is researched. A phase detection method of the space optical hybrid is proposed. The detection method is used to build experiment and the validity of the phase compensated crystal is proved by experimental data. Mechanical structure of the new style space optical hybrid is designed. The device can be applied to the space coherent receiving system.
