Abstract
A spectral domain optical coherence tomography apparatus for measuring a sample. The spectral domain optical coherence tomography includes a broadband light source, that supplies broadband light to the sample and a reference. The spectral domain optical coherence tomography apparatus includes a wavelength selective switch that receives mixed light that is a combination of the broadband light that is reflected off the sample and the reference. The spectral domain optical coherence tomography apparatus includes a sensor that includes a plurality of pixels. The wavelength selective switch guides a first portion of the mixed light that is within a first wavelength and a second wavelength to the sensor during a first period of time. The wavelength selective switch guides a second portion of the mixed light that is within a third wavelength and a fourth wavelength to the sensor during a second period of time.
