Abstract: A compact grating-mirror magneto-optical trap (GMOT) cold atom inertial sensor head is disclosed. To make the sensor head compatible with the high vibration levels encountered in dynamic environments, the number of optical ports in the vacuum chamber is minimized and various components, including fixed optical components and a reflective grating chip, are hard mounted within the vacuum chamber. The use of the reflective grating chip reduces the number of optical ports required for cooling beams from six to one. The number of optical ports is further reduced by time multiplexing multiple beams passing through a given optical port.

Abstract: Technologies pertaining to a multi-aperture optical imaging system are described herein. The multi-aperture optical system comprises an afocal optical telescope and a plurality of sub-apertures that receive light from the telescope. Each sub-aperture comprises a focusing optic that creates a full-field image onto an individual image sensor that outputs data indicative of an intensity of light received at the sensor. Image processing techniques can be used to combine the sensor outputs for spectral discrimination, to improve dynamic range or to enhance resolution of a scene.
