Abstract
Systems and methods for performing contactless wellhead displacement measurements in a desert environment include adjusting an alignment of optical components in an optical system based on a temperature of the optical system. A pattern of infrared light is projected from the optical system onto a portion of a wellhead, the infrared light having a wavelength away from water absorption wavelengths and solar maxima wavelengths. Reflections of the pattern of infrared light from the portion of the wellhead are captured using an imaging sensor of the optical system. A displacement of the wellhead is measured based on the projected pattern of infrared light and the reflections.

- capturing reflections of the pattern of infrared light from the portion of the wellhead using an imaging sensor of the optical system;
- and
- measuring a displacement of the wellhead based on the projected pattern of infrared light and the reflections.
A system for performing contactless wellhead displacement measurements in a desert environment, the system comprising:
- an infrared light source to illuminate a portion of the wellhead, the infrared light source having a wavelength away from water absorption wavelengths and solar maxima wavelength;
- a diffractive optical element to generate a pattern of light from the infrared light source;
- an imaging sensor to capture the pattern of light reflected from the portion of the wellhead;
- and
- a computer system configured to adjust an alignment of the infrared light source, the diffractive optical element and the imaging sensor based on a temperature of the system and measure a displacement of the wellhead based on the captured pattern of light.
