Abstract: The present disclosure provides an optical imager and a method for imaging electromagnetic radiation. In one aspect, the optical imager includes an object array substantially located at an object plane, a first catadioptric element configured to substantially collimate, at a central plane, electromagnetic radiation emanating from the object array, a second catadioptric element configured to image the substantially collimated electromagnetic radiation from the central plane onto an image plane, and a detecting element substantially located at the image plane. The first catadioptric element includes at least one refractive surface and at least one reflective surface, and the second catadioptric element includes at least one refractive surface and at least one reflective surface.

Abstract: The present disclosure provides an optical system. In one aspect, the optical system includes a plurality of imagers configured to emit an electromagnetic radiation, a plurality of optical sensors configured to receive the electromagnetic radiation from the imagers, and a beam splitting device disposed at an optical path between the imagers and the optical sensors. In one example, the beam splitting device is a multi-way beam splitter configured to receive the electromagnetic radiation from one of the imagers and separate the received electromagnetic radiation into a plurality of portions, each separated portion of the received electromagnetic radiation being directed to one of the optical sensors.
