This article [J. Biomed. Opt. 14, 064033 (2009)] was originally published online on 31 December 2009 with errors in Table 1 . The following corrections were made:

  • 1. In column 2, row 2, the first numeral 2 underneath the square root bracket was removed;

  • 2. In column 2, row 4, θcompensated was changed to θdispersion . Also “gratting” was changed to “grating.”

  • 3. In column 4, row 6, the value “627” was changed to “672.” The corrected table appears below.

In addition, in the line following Eq. (11) on page 8, the first super script −7 was corrected to −5 to read “with the parameters λ=7.2×105 cm, c=3×105 cm/fsec”. All versions of the article were corrected on 12 January 2010 and the article appears correctly in print.

Table 1

Theoretical spectral dispersion and compensation of TeO2 AODs. The following parameters are used: wavelength λ=720 nm; spectral bandwidth Δλ=3.68 nm; AOD aperture D=10 nm; acoustic velocity v=676 m/sec; scan range θscan=42.6 mrad; diffraction θdiffraction=0.0634 mrad; grating pitch d=150 grooves/mm; effective compensation frequency fcomp=vd2=71.1 MHz; and compensation θgrating=2Δλfcomp/v=552 μrad.

fmin =50 MHz f0 =70 MHz fmax =90 MHz
2-D spectral dispersion θdispersion Δλfx2+fy2/v 385539639 μrad
Dispersed resolution N θscan/θdispersion 1107961 spots
Spot elongation S θdispersion/θdiffraction 6.1×8.5×10.9×
2-D spectral dispersion θcompensated |θdispersionθgrating| 16713.1141 μrad
Compensated resolution N θscan/θcompensated 2536721302 spots
Compensated spot elongation S θcompensated/θdiffraction 2.64×0.21×2.22×

When θcompensated<θdiffraction , the number of compensated spots becomes N′=θscan/θdiffraction , and the scanning is diffraction limited.
