AB  - We propose a novel method called compressed sensing with linear-in-wavenumber 
      sampling (k-linear CS) to retrieve an image for spectral-domain optical coherence 
      tomography (SD-OCT). An array of points that is evenly spaced in wavenumber 
      domain is sampled from an original interferogram by a preset k-linear mask. Then 
      the compressed sensing based on l1 norm minimization is applied on these points 
      to reconstruct an A-scan data. To get an OCT image, this method uses less than 
      20% of the total data as required in the typical process and gets rid of the 
      spectral calibration with numerical interpolation in traditional CS-OCT. 
      Therefore k-linear CS is favorable for high speed imaging. It is demonstrated 
      that the k-linear CS has the same axial resolution performance with ~30 dB higher 
      signal-to-noise ratio (SNR) as compared with the numerical interpolation. Imaging 
      of bio-tissue by SD-OCT with k-linear CS is also demonstrated.
