At first, measuring optical path is improved, and some equipments such as aspherical mirror, high precision CCD camera are employed to eliminate the subjective error; with the analysis of the optical path, the mathematical model of triaxial parallelism is built, and the error factors are analyzed and calculated.
DHM can provide diffraction-limited lateral resolution comparable to common optical microscopy, and is capable of measuring optical path or thickness with sub-wavelength accuracy [ 25, 31].
As UHR-AO-OCT measures optical path length (not physical length), we assumed a refractive index of the OS of n os = 1.43 in all subjects [ 36].
PCI instruments measure the optical path through a lens and convert this to a true thickness using an assumed constant average refractive index nav.
By integration of the calculated velocity v z(t) over the time course of the laser irradiation the total local displacement Δ z(t) of the tissue, measured in optical path lengths, was calculated.
We discuss the recent measurements of our telescope-plus-detector throughput by direct monochromatic illumination by Cramer et al. This technique measures the whole optical path through the telescope, auxiliary optics, filters, and detector under the same conditions used to make SN measurements.
Further the optical intensity at the output port of a MZI has been measured while the optical path length difference was tuned by creating a temperature difference between the two arms of the MZI.
The absorption spectra of the same solution were measured in an optical path perpendicular to the photoactivation light.
The results were expressed as mean residue ellipticity, the units being deg × cm × dmol−1 according to the = θ λ /(100lcn) function, where θ λ is measured ellipticity, l the optical path length, c peptide/pseudopeptide concentration and n the number of amino acid residues in the sequence of interest.
