采用波前编码方法控制红外成像系统的热离焦像差。讨论了采用波前编码技术的热化系统设计方法。采用三次相位掩模设计了一种工作温度为-40℃~ 60℃的热化长波红外光学系统。计算机模拟和首次实验演示验证了该波前编码热化系统的性能，并澄清了与其实现相关的问题。
We use a wavefront coding approach to control thermal defocus aberration in an IR imaging system. The design method of athermalized system using a wavefront coding technique is discussed. An athermalized long wave IR optical system, which works at temperatures ranging from -40 °C to 60 °C, is designed by employing a cubic phase mask. Computer simulations and the first experimental demonstration are executed to verify the performance of this wavefront coded athermalized system and to clarify the issues related to its implementation.
