Automatic alignment and focusing fundus or anterior segment imaging system and method

Abstract

The invention provides an automatic alignment and focusing fundus or anterior segment imaging system. The system is placed on an X-Y-Z three-axis electric platform. The system comprises an illumination unit, an imaging unit, a guide alignment unit, an optical coherence tomography (OCT) unit and an eyepiece (201). The imaging unit comprises an imaging light path and a light path conversion device.When the system performs anterior segment imaging, the light path conversion device is moved into the imaging unit; and when the system performs fundus imaging, the light path conversion device is removed from the imaging unit. According to the invention, anterior alignment is realized through an anterior alignment unit, fundus alignment is realized through the guide alignment unit, or anterior alignment and fundus alignment are realized directly through the guide alignment unit, so that anterior segment and fundus imaging is realized, a professional technician does not need to be equipped inthe whole operation process, and the whole operation process is autonomously completed by the imaging system. The imaging system is awakened from a dormant state through a signal of a pressure sensorI and is in a dormant state in a non-working period, so that the energy consumption of the system is reduced. Therefore, unattended eye imaging is realized.

Description

technical field [0001] The invention relates to equipment for inspecting eyes, in particular to a fundus or anterior segment imaging system and method for automatic alignment and focus adjustment. Background technique [0002] Eye lesions usually need to be detected by anterior segment or fundus imaging. For example, macular disease lesions appear in the fundus, and early treatment of the disease requires early detection of lesions. Fundus imaging includes the imaging of the fundus surface, which is completed by the fundus camera; the two-dimensional cross-sectional imaging and three-dimensional imaging in the fundus tissue are completed by the OCT system. The use of existing fundus imaging equipment requires the person to be inspected to place his head on the jaw rest and forehead in the inspection equipment, and then a trained person, such as a doctor or an optometrist, manually adjusts and moves the inspection. The equipment performs alignment, focusing, and shooting ins...

Problems solved by technology

The use of existing fundus imaging equipment requires the person to be inspected to place his head on the jaw rest and forehead in the inspection equipment, and then a trained person, such as a doctor or an optometrist, manually adjusts and moves the inspection. The equipment performs alignment, focusing, and shooting inspections. This inspection process requires the operator to undergo professional training and relies on the operator's skills and experience. There are professional requirements for the operator, which limits the promotion and popularization of eye imaging equipment, and increases The labor cost of the equipment user unit is not conducive to reducing the inspection cost of the user
