Fiber-type image capturing method and apparatus thereof

Abstract

A fiber-type image capturing apparatus includes a fiber optic, an optical rotating module, an outer tube, an air inlet hole, and an air outlet hole. The optical rotating module is connected to one end of the fiber optic and has a light forward exit and a light lateral exit. The optical rotating module further includes a stator, a rotor, and a light path selector. The stator is fixed correspondingly to the fiber optic. The rotor has a fan blade which is pivotally connected to the stator. The light path selector is installed at the rotor and has a forward scanning path and a lateral scanning path. The outer tube fixes the fiber optic and the optical rotating module. The air inlet hole is disposed at the outer tube and feeds the fan blade with air. The air outlet hole is disposed at the outer tube and vents the air.

Description

technical field [0001] The present invention relates to an image capture method and its device, and in particular to a fiber-optic penetrating image capture method with both forward scanning and side scanning and its device. Background technique [0002] Probes for endoscopy, optical coherence tomography (OCT) or microscopy require small and preferably non-contact scanning probes. Fiber-optic probes perform optically and have these advantages. [0003] However, almost all existing fiber optic probes can only scan sideways, and very few can do forward scanning, but they are limited to forward scanning and cannot take into account sideways. These unidirectional scanning designs have their disadvantages when scanning. Take the optical coherence tomography fiber optic probe as an example to illustrate as follows: [0004] For the optical coherence tomography optical fiber probe with lateral scanning, since only the lateral information can be obtained, but the forward informati...

Problems solved by technology

However, since the forward information cannot be obtained, there are still risks and blind spots in medical use; and because the center of the scanning reflective surface of the system is usually still a few millimeters away from the end of the probe, the end of the probe must be advanced by a few millimeters before the scanning position, so that a certain Some applications are not suitable

[0005] For the probe with known forward scanning design, since the lateral information cannot be obtained, when the lateral scanning is required, the probe must be withdrawn and replaced with a lateral scanning probe for lateral scanning

This way of use is not ideal, it consumes operation time and increases system cost
