Modular Optronic Periscope
First Claim
1. A modular optronic periscope, comprising:
- a staring module including a plurality of static sensors providing image data for a wide field of view, each static sensor having nominal pixel resolution of at least approximately 0.33 mRad in the visible waveband;
an image processor operable to receive image data from the plurality of static sensors and to stitch together the received image data into a single continuous image;
a pointing module including a rotatable mirror providing an optical bundle for a multi-spectral narrow field of view of less than approximately four degrees and at a resolution higher than the wide field of view provided by said staring module;
an optical platform operable to image the optical bundle from said pointing module onto photosensitive devices to form a two dimensional image array; and
image derotation circuitry operable to reposition each pixel of said image array before display.

Abstract
A modular optronic periscope includes a staring module, having a plurality of static sensors providing image data for a wide field of view at moderate resolution, and an image processor, by way of which image data from the static sensors are stitched together into a single continuous image. A multi-spectral, narrow field of view at a higher resolution than the staring module is produced using a pointing module including a rotatable mirror, and a collimated optical bundle from the pointing module is imaged by way of an optical platform onto photosensitive devices to form a two dimensional image array. Each pixel of the image array is repositioned by way of image derotation circuitry before display.
