Abstract: A laser spectroscopy assembly for gas measurement is provided. The assembly includes a gas cell. The cell body includes an input optic. The assembly also includes a light source configured to emit laser light into the gas cell. The assembly further includes an optical mask positioned in an optical path of the laser light and positioned between the gas cell and the light source. The optical mask includes a surface forming an angle with the input optic, the angle unequal to zero or 90°. The optical mask also includes an entry defined in the surface and sized to admit the laser light therethrough. The entry is positioned in the optical path. The optical mask is configured to reduce noise from etalons caused by parallel surfaces and/or quasi-parallel surfaces in the optical path.

Abstract: A system is described for controlling access to resources using an object model. Users can specify use cases for accessing resources. The user may be granted access if the user satisfies qualifications required for accessing the resource, selected a use case permissible for accessing the resource, and satisfies qualifications required for the use case. Use cases, qualifications, resources, and/or links between them can be implemented using an object model. The system can be used in addition to authentication and authorization.
