Sentence examples for between the sample arm from inspiring English sources
A second-order software dispersion compensation algorithm [ 29] was sufficient to correct for any residual unmatched dispersion between the sample arm and D-ODL.
The second set of experiment, the slightly off-axis case, the angle between the sample arm and the reference arm is adjusted to meet slightly-off-axis geometry's demand and then the interferogram is captured.
This FWHMroll-off corresponds well with the experimentally measured roll-off function, measured from the reflection of a glass slide in the sample arm as a function of ΔOPL between the sample arm and the reference arm (Fig. 3).
To compensate for the differences in dispersion and optical path length between the sample arm and reference arm, hardware compensation was adopted using the same optical elements, such as an objective lens and cover glass, in both sample and reference arms.
A spectrograph detects the spectrum iD, which (for a single reflector) is modulated by the optical path length difference between the sample arm and the reference arm ΔOPL = 2 xS – xR), with sample arm length xS and reference arm length xR: where k is the wavenumber (k = 2π/λ) and IS and IR are the signal intensities from the sample and reference arm, respectively.
As a result, the frequency shift imposed on the spectral interferogram does not affect the group pathlength difference between the reference and the sample arm.
The OSIRIS-REx mission provides a much more limited opportunity to constrain the regolith strength, based on the surface interaction between the sampling arm and the surface.
The SLD light is fiber coupled and split between a reference mirror and sample arm using a 50/50 fiber coupler while X-Y galvos in the sample arm perform lateral scanning.
The sample arm of the interferometer is described subsequently.
The reference arm length matches the sample arm length which is set by the position of the imaging sample.
The sample arm is focused with a LSM003 (Thorlabs Inc).
