[Abstract]:In this paper, the basic concept, main task, working process, development status and typical products of helmet display are summarized. The working principle and general composition of HMD optical system are introduced. In this paper, the structure and design requirements of airborne helmet-mounted sighting / display optical system are discussed in detail. The hyperboloid optical structure is determined as the final design scheme, and the optical system of goggle-type helmet display is designed. The design of off-axis aspheric optical system of helmet display is optimized by using CODE-VC9.5), which makes the whole structure of helmet sighting more reasonable and practical. The optical properties and distortion characteristics of the optical system are analyzed. The algorithm and software correction method for the distortion of the optical system is studied, and the distortion correction for the optical system of the goggle-type helmet display is carried out. The results show that the corrected optical system has high imaging quality. When the spatial frequency is 501p/mm, the full field modulation transfer function is close to 0.2 and the distortion is less than 0.5. The system meets the performance requirements of airborne goggle-type helmet displays. Finally, the key technology and development trend of helmet display optical system are briefly analyzed.
