Problems solved by technology

The disadvantages of this probe are: first, the instability in the working process; second, due to the limited service life of the hose, the probe will be scrapped in advance
[0006] The Chinese patent publication number is CN102697455A, and the patent literature named "OCT Electronic Gastroscopy System" reports a technical solution for placing the driver inside the probe. The driver is directly connected to the reflective prism. The disadvantage of this structure is that it is difficult to install. Moreover, the driver is directly connected to the prism. During the dynamic scanning process, the reflected optical signal of the prism will be unstable, resulting in the reflected optical signal not being able to enter the transmission fiber.
Moreover, the use of this driver will generate noise, which will affect

Abstract

The invention discloses a novel optical probe which comprises a rotary assembly and a static assembly, wherein the rotary assembly and the static assembly are combined with each other through a rotary connector. The rotary assembly mainly comprises a reflecting prism used for reflecting light signals, a ringlike ultrasonic motor rotor, a light unthreaded hole and a self-focusing lens. The static assembly mainly comprises a ringlike ultrasonic motor stator, a self-focusing lens and a bearing. The ringlike ultrasonic motor stator and the motor are respectively fixed on a static sleeve and a rotary sleeve in an integrated mode. The friction force is generated after the ringlike ultrasonic motor is electrified, so that the whole rotary sleeve can conduct 360 degrees rotary screening. The screened light signals enter into the first self-focusing lens to exit parallel light through the reflective prism, and then the exited light enters into the second self-focusing lens to output screening information through transmission optical fibers. The novel optical probe is simple in operation, can not be interfered by electromagnetism in the process of working and can achieve the 360 degrees rotary screening. In addition, the novel optical probe is promising in market prospect, is good in technical transformation foundation and has wide social benefits at the same time.

Description

technical field [0001] The invention relates to a medical and optical detection instrument, in particular to an optical signal transceiving system with a rotatable scanning function. Background technique [0002] With the continuous development of photoelectric detection technology, various advanced detection technologies are applied in industrial and medical fields. OCT (Optical Coherence Tomography, Optical Coherence Tomography) is one of the detection technologies. It uses the basic principle of weak coherent light interferometer to detect the back reflection or several scattering signals of incident weak coherent light at different depths of biological tissue. , through scanning, two-dimensional or three-dimensional structural images of biological tissues can be obtained. At present, this technology is mainly used in the medical field. This technology puts forward strict requirements on the probe when performing biomedical testing. The probe should be as small as possib...
