Problems solved by technology

[0003] 1. The power supply and the rotating device are connected by wired power supply. In this power supply method, the cable is often pulled by the rotation of the rotating part, which is easy to fatigue and break, which affects the service life of the instrument; the number of revolutions of the rotating device is limited.
[0004] 2. In order to prevent the cable from being damaged, the limit design is also complicated
[0005] 3. The safety of the equipment is difficult to guarantee after the limit is improper or the cable is damaged
[0006] 4. In addition, it must be reversed and reset before the next use
In this power supply method, the contacts are easily worn or oxidized, resulting in poor contact; due to assembly or mechanical failure, it is also easy to cause poor contact
[0008] As announced on September 15, 2010, the Chinese invention patent with the publication number CN 101828900 A provides "an axis-shifting tomography device", which basically realizes the rotating scanning function well, but uses a power supply cable for power supply, and its Claim 1 also clearly states "wired connection", so its rotation, return, installation and maintenance are bound to be inconvenient
[0009] At present, there is no axial shift tomographic eye scanning system and method that overcomes the above defects and has a simple structure, convenient assembly, reliable performance, and free rotation.

Abstract

The invention discloses a tilt-shift tomography eye scanning system and a method thereof, relates to the field of optical instruments for the ophthalmology, and aims at solving the problem of inconvenient rotation. The scanning system comprises a light source (1), a fracture diaphragm (2), a rotary disc assembly (3), a projecting mirror group (4), a reflective device (5), eye forepart tissues (6), an eye (7), tilt-shaft imaging lenses (8), tilt-shift cameras (9), focusing lenses (10), focusing cameras (11), a rotary shaft (12), a fixed support assembly (13), a bearing (14), a large belt wheel (15), a belt (16), a small belt wheel (17), a motor (18), a main circuit board (19), a power converter (20) and an auxiliary circuit board (21); a primary coil 922), a secondary coil (23) and an electrical storage device (24) are further arranged; and the rotation is convenient after power supply cables are omitted due to adoption of a wireless power supply or charge mode. The tilt-shift tomography eye scanning system and the method thereof are mainly used for shooting eye forepart tissues.

Description

technical field [0001] The invention relates to the field of ophthalmic optical instruments, in particular to an axis-shifting tomographic eye scanning system and a method thereof. Background technique [0002] At present, the following specific defects generally exist in the shift tomography eye scanning devices at home and abroad: [0003] 1. The power supply and the rotating device are connected by wired power supply. In this power supply method, the cable is often pulled by the rotating part, which is prone to fatigue and fracture, which affects the service life of the instrument; the number of revolutions of the rotating device is limited. [0004] 2. In order to prevent the cable from being damaged, the limit design is also complicated. [0005] 3. The safety of the equipment is difficult to guarantee when the limit is improper or the cable is damaged. [0006] 4. In addition, it must be reversed and reset before the next use. [0007] 5. Others use slip rings ...
