An optical probe for detecting a biological tissue includes a surface imaging module and a tomography capturing module. The surface imaging module captures and creates a surface image of the biological tissue, and at least includes a light source emitting a first detecting light. The tomography capturing module captures a tomography image of the biological tissue and receives a second detecting light. The first detecting light passes via a first optical path from the light source to an imaging sensor through the biological tissue, a telecentric lens, a first optical mirror, and a lens assembly in sequence. The second detecting light passes via a second optical path from a first collimator to the first collimator through a scanner, the first optical mirror, the telecentric lens, the biological tissue, the telecentric lens, the first optical mirror, the scanner, and the first collimator in sequence.

Optical probe for detecting biological tissue

An optical system adapted to detect an object including a beam splitting and combing element, a catheter, a focusing element, a deformation detecting module, and an object detecting module is provided. The catheter sleeves outside an optical fiber, and the optical fiber has at least one fiber Bragg gratings. The deformation detecting module and the object detecting module are coupled to the beam splitting and combing element. A first light is reflected by the at least one fiber Bragg gratings and then transmitted to the deformation detecting module. A second light is transmitted to and reflected by the object, so as to be transmitted to the object detecting module. A first wavelength range of the first light is different from a second wavelength range of the second light.

Optical system

Provided is an interferometer for inspecting a test sample. The interferometer includes: a light source for providing a light beam; a beam splitting element, splitting the light beam into first and second incident light, wherein the first incident light is reflected by the test sample into first reflection light; a reflecting element, reflecting the second incident light into second reflection light; an optical detection element, receiving the first and the second reflection light into an interference signal; and a signal processing module, coupled to the optical detection element, for performing spatial differential calculation on the interference signal to generate a demodulation image of the test sample.

Interferometer and imaging method therefor

A carrier with the optical registration function is disclosed. The carrier allows the registration of inspected results of the sampling images of the sample to the corresponding address codes of the address coding site of the carrier.

An image reconstruction method is described as follows. A structural image of an object is obtained. An actual optical detected result of the object is obtained. An inhomogeneous initial state is determined based on the structural image. At least one solution converged with the actual optical detected result is determined by iteratively calculating a physical model from the inhomogeneous initial state. The image of the object is reconstructed based on the solution.

Image reconstruction iterative method

A bidirectional optical scanner assisting in mammography is revealed. The optical scanner that calculates functional images obtained by diffuse optical tomography, used in combination with a mammography machine can reduce the number of mammograms taken and the dose exposure. The bidirectional optical scanner includes a first compression plate, a first optical detection module, a second optical detection module and a second compression plate. The same test position of the tested breast can be detected twice in different directions by the first and the second optical detection modules. No matter where the tumor is located, the tumor can be detected. Besides structural images provided by the mammography machine, functional tomographic images of the breast are obtained by the bidirectional optical scanner. Thus diagnostic accuracy in the detection of breast cancer is improved.
