Zemax (Zemax Development, Bellevue, WA) and ASAP Breault Researchh, Tucson, AZ) optical modeling software were used to characterize beam propagation of the OCT and LIF optical paths through the distal optics.
Appropriate design of optical paths (Fig. 2b) not only provided homogeneous optic field but also shortened the focusing distance, which helped us get the high-quality images within just 20-mm height shell.
The optical paths from all points on the wave to the image are therefore equal, so that the expanding wavelets are all in phase (vibrating in unison) when they reach the image.
In an imperfect lens, however, because of the presence of aberrations, the emerging wave is not a perfect sphere, and the optical paths from the wave to the image point are then not all equal.
Optical paths are identified by their wavelengths.
All interferometer optical paths are maintained in a vacuum.
Electrical paths are denoted by solid lines, optical paths by dashed lines.
All optical paths for the interferometer are housed in a vacuum.
Furthermore, probing with longer wavelengths we are able to time-resolve optical paths with faster relaxations.
Direct optical channels (DOCs) are introduced as the direct optical paths between nodes.
Concentration measurements were made along twenty optical paths using open-path tunable diode laser absorption spectroscopy.
