Introduction

Cartilage, or cartilage tissue, is made up of chondrocytes and intercellular matter. The matrix in the cartilage is gel and has greater toughness. Cartilage is a connective tissue that is primarily supportive. Cartilage does not contain blood vessels and lymphatic vessels, nutrients from the blood vessels in the perichondrium penetrate into the intercellular stroma, and then nourish bone cells.

Principle

Polarized light microscopy is a kind of microscope to identify the optical properties of the fine structure of a substance. Any substance with birefringence can be distinguished under a polarizing microscope. The characteristic of a polarized light microscopy is to change ordinary light into polarizing light for microscopic examination in order to identify whether a substance is monorefringent (anisotropic) or birefringent (anisotropic).
1. Monorefractivity and birefringence: When light passes through a substance, if the properties and path of light do not change due to the direction of illumination, this substance has "isotropy" in optics, also known as a single refractor, such as ordinary gases, liquids, and amorphous solids; If the speed, refractive index, absorption, polarization, amplitude, etc. of light passing through another material vary depending on the direction of illumination, this material has "anisotropy" in optics, also known as a birefringent material, such as crystals, fibers, etc.
2. Polarization of light: Light waves can be divided into natural light and polarized light according to the characteristics of vibration. The vibration characteristic of natural light is that there are many vibration planes on the vertical light wave conduction axis, and the amplitude distribution of vibration on each plane is the same. Natural light through reflection, refraction, birefringence and absorption, can be obtained only in one direction vibration of light waves, this light wave is called "polarized light" or "polarized light".
