Miniature large-field-of-view laser fuze transmitting-receiving optical system

Abstract

The invention relates to a miniature large-field-of-view laser fuze transmitting-receiving optical system. The miniature large-field-of-view laser fuze transmitting-receiving optical system is composed of three transmitting optical systems and three receiving optical systems; the three transmitting optical systems and the three receiving optical systems are arranged in series in a circumferential direction; each transmitting optical system and each receiving optical system are arranged adjacently and alternately; an included angle between the central optical axes of two adjacent transmitting optical systems is 120 degrees; an included angle between the central optical axes of two adjacent receiving optical systems is 120 degrees; in an arc vector direction, each transmitting optical system uses a 120-degree transmitting field of view, and each receiving optical system uses a 120-degree transmitting field of view; and in a meridian direction, each transmitting optical system uses a 1-degree transmitting field of view, and each receiving optical system uses a 2-to-8-degree receiving field of view. With the miniature large-field-of-view laser fuze transmitting-receiving optical system of the invention adopted, laser fuze can perform large-field-of-view, circumferential and leakage-free detection on any target, and a requirement for the miniaturization of the laser fuze is satisfied. The miniature large-field-of-view laser fuze transmitting-receiving optical system has the advantages of accurate target positioning, high detection precision and strong anti-interference capability.

Description

technical field [0001] The invention relates to an optical system for sending and receiving by using a laser fuze, in particular to a miniaturized and large field of view laser fuze sending and receiving optical system, which belongs to the field of laser fuzes. Background technique [0002] Laser fuze is a new type of fuze that uses laser beams to detect or perceive targets, and determines the optimal detonation time of missile warheads by analyzing target echo signals. The working principle of its transmission and reception is as follows: figure 1 As shown in Fig. 1, the laser is first made to emit light through the electric pulse signal, and then the laser beam is shaped by the transmitting optical system, so that the shaped laser beam radiates to the space according to the requirements of the emission pattern, and diffuse reflection echoes are generated when the target is detected The signal is collected to the photosensitive surface of the detector through the receivin...
