Abstract: Systems and methods which provide a high-throughput point source light coupling structure (120) implementing a condenser (122) configured according to one or more condenser (122) configuration rules are described. Embodiments of a high-throughput point source light coupling structure (120) utilize a birefringent plate (341, 342) configuration in combination with a condenser (122) and point source (121) to provide a light coupler structure (120) for a birefringent-static-Fourier transform interferometer implementation. According to some examples, the optical axis of a first and second birefringent plate (341, 342) of a birefringent plate (341, 342) configuration are not in the same plane. The condenser (122) of the high-throughput point source light coupling structure (120) of embodiments is provided in a defined (e.g., spaced, relational, etc.) relationship with respect to the point source (121) and/or a camera lens (131) used in capturing an interference pattern generated by the light coupling structure (120). The high-throughput point source light coupling structure (120) herein may be provided as external accessories for processor-based mobile devices (130) having image capturing capabilities.

Abstract: The present application relates to a system for performing time-resolved interferometric spectroscopy of incoming light. In some embodiments, the system includes one or more optical elements, a photo-detector, a capacitance detector, and one or more processors. Upon application of a varying input signal to the one or more optical elements, a change to an optical characteristic is caused resulting in a changing interference pattern produced by the incoming light incident on the one or more optical elements. During the application of the varying input signal, the photo-detector may detect an intensity of light output from the one or more optical elements and the capacitance detector may detect a capacitance of the one or more optical elements.
