Table 2 Simulated and experimental beam characteristics.
From: Quantifying the influence of Bessel beams on image quality in optical coherence tomography
Beam type (in free space) | Gaussian | Bessel |
|---|---|---|
Transverse resolution, FWHM | 2.6 | 2.6 |
Depth of field (μm) | 40 | 330 |
Irradiance penalty (dB) | 0 | 7.5 |
