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, was changed to . Also “gratting” was changed to “grating.”
3. In column 4, row 6, the value “627” was changed to “672.” The corrected table appears below.
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||Δλfx2+fy2/v||385||539||639 μrad|
|Dispersed resolution||θscan/θdispersion||110||79||61 spots|
|2-D spectral dispersion|||θdispersion−θgrating|||167||13.1||141 μrad|
|Compensated resolution||θscan/θcompensated||253||672||302 spots|
|Compensated spot elongation||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.
