The phrase "along the optical path" is correct and usable in written English.
It can be used in contexts related to optics, physics, or engineering when discussing the trajectory or route that light takes through a system.
Example: "The lens was positioned to focus the light along the optical path to ensure maximum clarity."
Alternatives: "through the optical route" or "across the optical pathway."
For this reason a numerical simulation, based on the evaluation of the beam along the optical path, was performed in order to achieve the optimum condition (Fig. 1c).
The spectrally resolved imaging is obtained by two different methods: scattering through a grating monochromator and interposition of interference filters along the optical path.
The presence of different phase contents and various interfacial features along the optical path gives rise to attenuation and scattering and makes the identification possible.
By aiming at the inhomogeneity and uncertainty of the horizontal aerosol in practice, a joint retrieval method is proposed to retrieve the aerosol extinction coefficients (AEC) from the raw data along the optical path.
For quantitative measurements the influence of self-absorption and laser attenuation were found to be not negligible and an error of 12% was found as sum of the self-absorption and laser attenuation along the optical path.
A relay lens RL then conveys the schlieren beam to camera C. Due to its large light source and aperture, this schlieren system has a narrow depth of focus at S, which is useful in isolating S from other refractive disturbances elsewhere along the optical path.
Different from the refractive lens array relying on phase modulation via phase change accumulated along the optical paths, metasurfaces composed of nano-scatters can produce phase abrupt over the scale of wavelength.
Gradients in the optical path along the selected direction are better visible for higher values of the shear pixels number.
For the emission excited along the confocal plane, our results also indicate that the effects related to the optical path inside the cell wall are not so important.
The laser beams is sent into the optical path of the microscope.
The optical insertion loss for the array typically varied from 2.3 dB for a single trench in the optical path (shortest optical path) to 8 dB for 15 trenches in the optical path (longest optical path).
