Design of Reflective/Diffractive Objective Optical System for Handed Low-Light Night Vision Google

For the design direction of low-light night vision goggle become more and more miniaturization and high image quality[1], this artical design a reflective/diffractive objective optical system with optical software ZEMAX. It combines diffractive elements with reflective elements to design a reflective/diffractive objective with a 14.5 degrees field of view and a 1.0 / 1.2 relative aperture and a 95mm focal length, and it introduces an improved method based on primary aberration theory in reflective/diffractive hybrid optical system. Etching diffractive optical element on the mirror can be usful for correcting aberration and improving the image quality.
