Abstract

The invention relates to cornea three-dimensional detection equipment, and particularly relates to cornea three-dimensional detection equipment based on an optical coherence elastography principle. The cornea three-dimensional detection equipment based on the optical coherence elastography principle is easy to operate, the working mode is optimized, and therefore the labor cost is reduced; meanwhile, the position of a lens can be adjusted, and the equipment is suitable for various eye distances. The cornea three-dimensional detection equipment based on the optical coherence elastography principle comprises a main frame, a switch key, an imager, guide pipes and a sliding mechanism, the sliding mechanism is arranged on the upper portion of the main frame, the starting switch key is arranged on the sliding mechanism, the imager is arranged in the sliding mechanism in a sliding mode, and the guide pipes are symmetrically arranged on the sliding mechanism in a sliding mode. A permanent magnet is attracted to a limiting block, and therefore the opening state of a display screen is fixed; in cooperation with reading and observation of data, after the equipment is used, the display screen can be pushed to rotate and be recycled, and the display screen is prevented from being collided and damaged.

Description

technical field [0001] The invention relates to a three-dimensional corneal detection device, in particular to a three-dimensional corneal detection device based on the principle of optical coherence elastic imaging. Background technique [0002] According to the principle of optics, the object distance in the outside world is inversely proportional to the imaging distance in the human eye. When people use their eyes at close range for a long time, they will mobilize the physiological synchronous near reflex adjustment function of the eye, and complete or make up for this by themselves through the refractive adjustment reaction. This process is medically called an adjustment response, but when the adjustment mechanism encounters damage from various factors inside and outside the body, such as long-term fatigue eye use, the adjustment tension and tension of the ciliary muscle and the orbital orbicularis muscle are caused. Convulsions, when you look at distant objects, you can...
