This configuration generates a wavelength-dependent stationary interferogram from which the input spectrum is retrieved in a single shot without scanning elements. Furthermore, fabrication and experimental deviations from the ideal behavior of the device are corrected by spectral inversion algorithms. The spectral resolution of our system can be readily scaled up by incorporating longer optical fiber delays, providing a pathway toward surpassing current spectroscopy resolution limits.engjournal articlehttp://dx.doi.org/10.1364/OL.38.002262http://www.opticsinfobase.orgopen access535Spatial Heterodyne SpectrometerWave-GuideÓptica (Física)2209.19 Óptica Física
