Abstract: 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.

Abstract: 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.
