Using an axicon lens with a top angle of 165 degree, nearly constant lateral resolution of ~ 5 micro meter over a focusing depth of at least 1.29 mm is demonstrated with an invariant sensitivity of ~ 94 dB.景深貝索光束掃頻式光學同調斷層攝影術軸稜鏡Depth of fieldBessel beamSwept source optical coherence tomographyAxicon
