Off-axis reflective optics system with ellipsoidal mirror as main mirror

Abstract

The invention relates to an off-axis reflective optics system with an ellipsoidal mirror as a main mirror and belongs to the field of intensive laser close range damage. The off-axis reflective optics system with the ellipsoidal mirror as the main mirror is composed of an ellipsoidal reflective mirror (1) and a parabolic reflective mirror (2), super laser emitted by a laser first enters the parabolic reflective mirror (2) in an incident mode, then reflects to the ellipsoidal reflective mirror (1) through the parabolic reflective mirror (2), the super laser is gathered to a focus through the ellipsoidal reflective mirror (1) to damage and hit a target. A long-axis focus F2 of the ellipsoidal reflective mirror (1) coincides with a focus F1 of the parabolic reflective mirror (2), and a long axis of the ellipsoidal reflective mirror (1) coincides with the long axis of the parabolic reflective mirror (2). The off-axis reflective optics system with the ellipsoidal mirror as the main mirror optimizes an optics system based on a traditional off-axis reflective optics system with a parabolic mirror as a main mirror, improves close range converging capacity of emergent laser and system fighting efficiency on the premise of no change of an original system volume, weight and processing cost.

Description

technical field [0001] The invention relates to an off-axis reflective optical system, in particular to an off-axis reflective optical system with an ellipsoidal mirror as a main mirror, belonging to the field of strong laser near-distance damage. technical background [0002] According to the needs of the rapidly developing short-range air defense military field, the application of laser damage devices is becoming more and more extensive. The combat distance of this type of laser damage device is mainly concentrated in the range of 500m to 3km. Therefore, the converging spot of the laser output system also needs to reach the maximum energy within this range of action. The traditional structure of the laser output system consists of two off-axis parabolic mirrors to form an afocal optical system with parallel light incident and parallel light output. The best working point of the system’s outgoing laser is at ∞ distance. For short-distance targets, the system relies on the ...
