example 1

[0035] Example 1 includes a vacuum chamber apparatus for an atomic sensor, the apparatus comprising: a chamber wall surrounding an enclosed volume, the chamber wall having a first open end and a second open end opposite the first open end; a first panel, It is on the first open end of the chamber wall and has a first surface facing the enclosed volume and having a first set of diffractive optics therein; and a second panel on the second on the open end and having a second surface facing the enclosed volume and having a second set of diffractive optics therein; wherein the first set of diffractive optics and the second set of diffractive optics are configured along predetermined The optical path reflects at least one light beam within the enclosed volume.

example 2

[0036] Example 2 includes the device of Example 1, further comprising one or more light ports configured to transmit at least one light beam into the enclosed volume.

example 3

[0037] Example 3 includes the device of Example 2, wherein the light ports include a first set of light ports that transmit the first set of light beams through the first panel into the enclosed volume; and a second set of light ports that transmit the second set of light beams through the second panel. A set of light beams is transmitted into the enclosed volume, wherein the first set of light beams and the second set of light beams propagate within the enclosed volume along the optical path but in opposite directions.

Abstract

System and methods for a vacuum cell apparatus for an atomic sensor are provided. In at least one embodiment, the apparatus comprises a cell wall encircling an enclosed volume, the cell wall having a first open end and a second open end opposite from the first open end and a first panel over the first open end of the cell wall and having a first surface, the first surface facing the enclosed volume and having a first set of diffractive optics therein. Further, the apparatus comprises a second panel over the second open end of the cell wall and having a second surface, the second surface facing the enclosed volume and having a second set of diffractive optics therein; wherein the first set of diffractive optics and the second of diffractive optics are configured to reflect at least one optical beam within the enclosed volume along a predetermined optical path.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Application 61 / 670766, filed July 12, 2012, the disclosure of which is incorporated herein by reference. Background technique [0003] Laser-cooled atoms are the basis for a class of precision sensors, including precise clocks, magnetometers, gyroscopes, and accelerometers. Often, cold atom sensors include a large vacuum cavity that isolates the atoms from the surrounding environment and provides a platform for mounting lasers and optics onto the body of the cold atom sensor. Recent efforts to miniaturize cold-atom sensors have made progress in reducing size, but this is based on physical packaging that requires traditional machining processes that are slow and expensive. Contents of the invention [0004] A system and method for a vacuum chamber arrangement for an atomic sensor is provided. In at least one embodiment, the device includes a chamber wall surrounding t...
