Integrated optical detection system

摘要

An optical detection system integrated within an electro-optical sighting and/or scanning system and a method to perform a rapid wide area search are disclosed. In one example, an integrated optics detection subsystem is configured with one-the-move processing methods to perform the optics defeat functions to during a wide area search or sector scan performed by the host electro-optical sighting system.

1. An electro-optical (EO) sighting system, including an integrated optics detection (OD) sub-system, comprising:
an EO optical module configured to scan and search a target area remote from the optical module, the EO optical module including: a multi-function laser configured to generate and emit at least one laser beam external to the optical module to search the target area; an imager sub-system configured to receive reflected laser radiation from the target area; and afocal optics coupled to the imager sub-system and configured to direct the reflected laser radiation to the imager sub-system, the afocal optics including a movable backscan mirror; a controller coupled to the EO optical module and configured to pan the EO optical module to sweep the at least one laser beam across the target area to perform a scan of the target area; a video processor coupled to the imager sub-system and configured to process data received from the imager subsystem and to provide video outputs representative of the scan of the target area; and the integrated OD sub-system configured to detect threat optics in the target area and including:
an OD interrogator source integrated with the EO optical module and coupled to the backscan mirror, the OD interrogator source being configured to generate an interrogation beam, and the backscan mirror being configured to direct the interrogation beam into the target area; andan OD receiver integrated with the imager sub-system and coupled to the movable backscan mirror, the OD receiver being configured to receive and image a retro-reflection of the interrogation beam from the threat optics, and the movable backscan mirror being configured to direct the reflected electromagnetic radiation from the target area to the OD receiver; wherein the video processor is coupled to the OD receiver and further configured to receive and process image data from the OD receiver and to determine whether the image data includes an image of the retro-reflection of the interrogation beam indicating a presence of the threat optics within the target area; and wherein the controller is further configured to control the movable backscan mirror to periodically hold an image of at least a portion of the target area, including the retro-reflection, stationary on the OD receiver so as to allow the OD receiver to obtain a substantially stationary image of the retro-reflection without disrupting the scan of the target area performed by the EO optical module.
