2.1, Early Imaging Technologies

1. The art of photography
Early in the 1800s, photography was developed, making it one of the first methods of picture capture. In traditional photography, light is captured on a photosensitive surface—such as film or a digital sensor—by use of a camera. Although photography could depict objects and scenes in two dimensions, it was not able to offer the depth information required for precise measurement and analysis.

2. Imaging with X-rays
When X-ray imaging was developed in the late 1800s, it made it possible to see inside objects and living things. X-rays have the ability to pass through a variety of materials and expose internal details that are hidden from view. X-ray imaging has become essential for materials analysis and medical diagnosis.

3. The stereoscopy
In the 19th century, stereoscopy—also referred to as 3D photography—was invented. To mimic human binocular vision, two photos were taken at slightly different angles. These pictures appeared three-dimensional and had depth when seen through a stereoscope. Nevertheless, stereoscopy was not able to create detailed 3D models; it was only able to provide visual depth perception.

4. The use of photogrammetry
The early 20th century saw the development of photogrammetry, which is the process of snapping several pictures of a scene or item from various perspectives and then reassembling the three-dimensional coordinates using mathematical formulas. Archaeology, topographic mapping, and architecture have all benefited from this method of measuring and charting items and landscapes.

5. Computerized Tomography
The 1970s saw the introduction of computed tomography (CT) scanning, which completely changed medical imaging. X-rays are used by CT scanners to create cross-sectional pictures of objects or bodily parts. After that, a 3D model is created by digitally reconstructing these cross-sections. CT scanning became an essential diagnostic tool for medicine because it produced detailed interior images.

6. MRI
The late 20th century saw the development of magnetic resonance imaging (MRI), which creates detailed images of the body’s soft tissues using radio waves and magnetic fields. MRI scanners are commonly employed in medical diagnostics, particularly for brain and spinal cord imaging, and they generate high-resolution images.

7. Infrared Tomography
Modern 3D scanning was made possible by the development of laser scanning technology in the middle of the 20th century. In the past, laser scanners measured surfaces’ distances using laser beams and produced intricate 3D representations. Architectural documentation, industrial measurement, and surveying all made use of these scanners.

8. Methodical Light Scanning
An item is projected with a predefined pattern of light, and cameras are used to record the pattern’s deformation. This technique is known as “structured light scanning,” and it predates contemporary 3D scanners. The technology is able to recreate the object’s surface in three dimensions by examining the distortions. Compared to previous methods, this technology produced 3D models that were more detailed and accurate.

2.2, Imaging Technologies of 3D Scanners

Methodical Light Scanning
Using structured light scanning, an object is covered in a variety of patterns, most commonly stripes or grids. The deformation of these patterns brought about by the surface of the item is captured by a camera or sensor. The scanner reconstructs the object’s three-dimensional shape by examining the distortions.

quick speed of scanning.
Ideal for catching small details.
Uses:
industrial examination.

2. Optical Scanning
A laser beam is used in laser scanning to determine how far an object is from its surface. Laser light is emitted by the scanner, and reflected light is detected by sensors. To compute the distance and create a 3D model, one can utilize either the phase shift of the reflected light or the time-of-flight of the light.
Benefits
