Abstract

Precision optics is the core component of space optical remote sensor. The excellent performance of precision optics is determined by the stability of its supporting structure in addition to the index of the optical component itself. With the development of laser additive manufacturing technology in China, more and more industries are using laser additive manufacturing to realize the structure and forming mode which cannot be realized by traditional processes. Laser additive manufacturing technology can effectively improve the consistency, stability, stiffness and low expansibility of structural parts, which are very important for the stability of precision optical systems. With the rapid development of space optical remote sensor demand, laser additive manufacturing technology has great advantages of integrated forming and short cycle. In this paper, a laser direct deposition additive manufacturing technology of precision optical support structure is proposed to form TC4 titanium alloy products, and a method to verify its stability is proposed, which is suitable for the development and stability verification of space precision optical support structure.
