Infrared imaging system

摘要

An infrared imaging sensor compatible with 2nd Generation Forward Looking Infrared (FLIR) Horizontal Technology Integration (HTI) B-Kit based sensors. In one example, the infrared imaging sensor includes a set of refractive opto-mechanical modules, including an afocal optical module, a receiver assembly, and backward- and forward-compatible electronics modules. The afocal optical module is configured to provide a plurality of different fields of view for the infrared imaging sensor. In one example, the sensor is configured for MWIR and LWIR imagery.

1. An infrared imaging sensor compatible with upgrade of second generation forward looking infrared (FLIR) B-kits, comprising:
a set of refractive opto-mechanical modules configured to receive and create video from infrared electromagnetic radiation in at least the mid-wave infrared (MWIR) and long-wave infrared (LWIR) spectral bands, the set of refractive opto-mechanical modules including an afocal optical module having an eyepiece and configured to provide a plurality of fields of view for the infrared imaging sensor; a receiver assembly including a detector in a Dewar optically coupled to the eyepiece and configured to receive the infrared electromagnetic radiation from the eyepiece and to generate an electronic image from the infrared electromagnetic radiation, the receiver further including an imager configured to direct the infrared electromagnetic radiation from the afocal optical module to the detector in the Dewar; and at least one electronics module configured to provide an electronic interface for the infrared imaging sensor, and to process the electronic image.
