Abstract: Systems and methods are provided for creating enhanced VR content. The system generates, for display on a user device, a view of a virtual 3D environment. The system receives, from the user device, a request to capture the view of the virtual 3D environment. The system accesses data used to generate the view of the virtual 3D environment for display on the user device. The system accesses additional data of the virtual 3D environment other than the data used to generate the view of the virtual 3D environment for display on the user device. The system generates an image based on (a) the data used to generate the view of the virtual 3D environment for display on the user device, and (b) the additional data of the virtual 3D environment.

Abstract: Systems and methods are provided for creating enhanced VR content. The system generates, for display on a user device, a view of a virtual 3D environment. The system detects that a location in the view of virtual 3D environment matches one or more criteria. In response to the detecting that the location in the virtual 3D environment matches the one or more criteria, the system automatically stores an image of the virtual 3D environment.

Abstract: This invention provides a tunable laser in which a plurality of gain elements (e.g., semiconductor diodes) with a plurality of gain spectra are optically coupled to a splitting-combining means (e.g., a wavelength router or fiber-optic coupler) in parallel, and the splitting-combining means is in optical communication with a wavelength-selecting means (e.g., a diffraction grating optically coupled to a movable mirror). The tunable laser of the present invention further comprising an optical fiber, optically coupling the splitting-combining means to the wavelength-selecting means. The use of a plurality of distinct gain spectra greatly enhances the tuning range of the tunable laser in the present invention.

Abstract: Method and system for cavity ring down spectroscopic analysis of non-cavity-filling sample. An interface of a sample (gas, liquid, thin film, bulk solid, etc.) is positioned at a Brewster angle relative to a p-wave polarized light beam propagating in an optical cavity so that substantially no light beam energy is lost by reflection at the interface. The light beam cycles one or more times in the cavity for each of a sequence of selected wavelengths, is extracted from the cavity, and is analyzed to determine an absorption spectrum for the sample. The cavity, except for the sample region may be filled with a solid, optionally dielectrically active and optionally having an electrical field applied thereto to vary the solid's refractive index according to the light beam wavelength used.

Abstract: Method and system for generating a sequence of two or more light beam central frequencies. A first mirror, in an optical cavity defined by two or more mirrors, is moved to a sequence of two or more locations relative to a second mirror in the cavity. The first mirror location is dithered relative to the second mirror for each location in the sequence to produce a light beam having a dithered sequence of cavity frequencies that are related to longitudinal mode resonant frequencies for the cavity. Alternatively, frequency locking is implemented for each of the sequence of central frequencies. The light beam may be passed through a sample within the cavity for spectroscopic measurements or may be extracted from an empty cavity to provide a sequence of light beam frequencies for a subsequent application.
