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: A method for evaluating skin tissue includes: obtaining a tomographic image of skin; performing a quantization process for quantizing brightness values of the tomographic image of skin to generate a quantized image; performing a binarization process on the brightness value of each image point in the quantized image according to a first threshold interval to generate a first filtered image; performing the binarization process on the brightness value of each image point in the quantized image according to a second threshold interval to generate a second filtered image; obtaining a first estimated tissue boundary according to the distribution of the bright spots in the first filtered image; obtaining a second estimated tissue boundary according to the distribution of the bright spots in the second filtered image; estimating a thickness of skin tissue according to a difference between the first and second estimated tissue boundaries.
