Elliptical polarization

The other kind of wave is a polarized wave. Polarized waves are light waves in which the vibrations occur in a single plane. Plane polarized light consists of waves in which the direction of vibration is the same for all waves. In the image above, you can see that a plane polarized light vibrates on only one plane. The process of transforming unpolarized light into polarized light is known as polarization. The devices like the polarizers you see are used for the polarization of light.

Linearlypolarized electromagnetic wave

In contrast, multiphoton microscopy uses excitation wavelengths in the infrared taking advantage of the reduced scattering of longer wavelengths. This makes multiphoton imaging the perfect tool for deep tissue imaging in thick sections and living animals. Applications range from the visualization of the complex architecture of the whole brain to the study of tumor development and metastasis  or the responses of the immune system in living animals.

Fluorescence microscopy comes to its limits when imaging thick samples. Visible light is strongly scattered in biological tissues and fluorescence imaging is therefore restricted to an imaging depth of around 100 µm.

Circularly polarized light

Circular polarization

How deep one can image with multiphoton microscopy depends on the tissue type, age of the tissue, quality of the staining but also on the excitation efficiency which is correlated to the peak power of the multiphoton laser and how well this peak power can be maintained in the imaging system.

Light is the interaction of electric and magnetic fields travelling through space. The electric and magnetic vibrations of a light wave occur perpendicularly to each other. The electric field moves in one direction and the magnetic field in another ‘perpendicular to each other. So, we have one plane occupied by an electric field, another plane of the magnetic field perpendicular to it, and the direction of travel is perpendicular to both. These electric and magnetic vibrations can occur in numerous planes. A light wave that is vibrating in more than one plane is known as unpolarized light. The light emitted by the sun, by a lamp or a tube light are all unpolarised light sources. As you can see in the image below, the direction of propagation is constant, but the planes on which the amplitude occurs are changing.

Linearlypolarized wave

Transverse waves are waves, in which the movement of the particles in the wave is perpendicular to the direction of motion of the wave.

Polarization, in Physics, is defined as a phenomenon caused due to the wave nature of electromagnetic radiation. Sunlight travels through the vacuum to reach the Earth, which is an example of an electromagnetic wave. These waves are called electromagnetic waves because they form when an electric field interacts with a magnetic field. In this article, you will learn about two types of waves, transverse waves and longitudinal waves. You will also learn about polarization and plane polarised light.

There are two linear components in the electric field of light that are perpendicular to each other such that their amplitudes are equal, but the phase difference is π/2. The propagation of the occurring electric field will be in a circular motion.
