  • Compact spectrometer having reflective wedge structure
    Patent number: 10830641
    Abstract: Systems and methods which provide a compact spectrometer using static Fourier transform interferometer (SFTI) cube configurations, such as are suitable for use with respect to mobile and portable electronic devices, are described. A SFTI cube of embodiments comprises a monolithic dual mirrored wedge beam splitter structure wherein mirrored wedge surfaces provide two reflective mirrors that are slightly tilted away from the orthogonal directions so that the resultant beams of light cross over one another and form an interference pattern. SFTI cube implementations of embodiments facilitate highly compact spectrometer configurations having a wide wavelength range, high resolution, high throughput, and low cost.
