ABSTRACT:
An optical detection apparatus includes a housing having a circumferential opening therein. A primary mirror reflects light rays to form a first set of light rays to a secondary mirror that has a generally concave shape coupled to the housing. A tertiary mirror having a generally concave shape coupled to the housing spaced apart from the secondary mirror directs light to detection optics that form an image using the third set of light rays. The detection optics include a micro-mirror array that redirect the image to a detector. A controller controls the micro-mirror array and determines an event characteristic based upon the image thereon.
