Abstract
Described herein are devices and methods for making extremely accurate measurements in a medium by continuously measuring the index of refraction of the medium such as water or biological tissue. Also described herein is a device for constantly measuring the index of refraction, and using the index of refraction data to constantly calibrate the optical measurement device. In addition, a primary measurement device (a ladar) that is optimized for data collection in a volume backscattering medium such as water or biological tissue is described, along with data results from the lab.
Claims15
A method of making range, angle, or imaging measurements in a medium, the method comprising the steps of:
- making a range, angle, or imaging measurement in a medium;
- measuring or calculating an index of refraction of the medium;
- and
- correcting the range, angle, or imaging measurement for errors associated with use of an approximate index of refraction different from the measured or calculated index of refraction of the medium.
