Optical measurement of aero-optics

OSA Annual Meeting, 1993
Optical measurements of aerodynamically induced optical degradation have evolved over the last few decades from commerical optical testing instruments to specialized aero-optic diagnostic systems. New diagnostic systems feature vastly increased temporal and spatial resolution and accuracy.

Optical Pachometry Measurements

Optometry and Vision Science, 1984
Polymethyl methacrylate (PMMA) lenses of known thickness were measured by one investigator with a pachometer. This experienced pachometrist held variation in thickness measurements to within 1% over time. The measurements were repeatable with a SD less than 1%.

Optical Spectral Measurement

2018
A monochromatic light is quantified by its brightness and color, i.e., its optical power and wavelength. And a light beam is normally composed of many monochromatic lights of different powers and wavelengths. In this chapter we discuss three optical dispersive devices, namely, prism, diffraction grating, and Fourier transform spectroscopy, to resolve ...

Optical Distance Measurement

1978
Two disadvantages with the direct measurement of distance discussed in chapter 1 are, firstly, that the measuring process takes place on the ground (if the terrain is undulating this can be very difficult) and, secondly, when a lot of linear measurements are required, taping can be laborious and time consuming.
