Photoelectric imaging is a process that converts light into an electric signal for capturing visual images. It is typically done using sensors or detectors that respond to light by generating an electrical current proportional to the intensity of the light. This electrical signal is then processed to create a digital image.
Photoelectric measurements are sensitive to the nature of the photoelectric surface because the surface properties, like work function and reflectivity, directly affect the efficiency of electron emission when photons are absorbed. The surface characteristics influence the energy required for electron liberation, impacting the overall photoelectric effect.
why are photoelectric measurements are so sensitive to the nature of the photoelectric surface
The photoelectric effect is used in devices such as solar cells to convert light energy into electrical energy. It is also used in photocells to control lighting in automatic systems, such as motion-sensing lights. Additionally, it is used in photography to capture images and in spectroscopy to analyze the composition of materials.
The photoelectric effect demonstrates the particle nature of light. In this phenomenon, light is shown to behave like a stream of particles (photons) by ejecting electrons from a material when it hits the surface.
The photoelectric current depends on the intensity of light shining on the surface, the frequency of the light, the type of material the surface is made of, and the energy of the individual photons. Increasing any of these factors can result in a higher photoelectric current.
Certainly, of course, and you betcha. The presence of air has no function or involvement in the photoelectric effect.
Colonoscopy is not typically considered a diagnostic imaging study. While it does use imaging for diagnosis, it is not usually done by radiologists.

Now days it would be done via satellite imaging.
The most common imaging methods are additional views on the mammogram, sometimes called magnification views, and ultrasound.

Photoelectric colorimeter is a medical term. Essentially, it is referring to a colorimeter using a photoelectric cell and appropriate filters instead of the eye.
Imaging tests such as computed tomography scans (CT scans), magnetic resonance imaging (MRI), ultra-sound, and fiberoptic scope examinations help doctors determine the location of the tumor even if it is deep within the body.

It is considered renewable. It photoelectric energy is created when the sun shines.
