Optical Imaging Techniques

Optical imaging techniques use light to create detailed pictures of the inside of the body or objects. They work by shining specific types of light—like lasers or LEDs—onto tissue or materials and capturing how the light interacts, such as how it scatters, absorbs, or emits. These methods can reveal structure, function, and even chemical composition, helping in medical diagnosis or scientific research. Examples include MRI, ultrasound, and endoscopy, each employing different lightweight technologies to provide clear, real-time images without invasive procedures.
