  • Patent number: 11026581
    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.

  • Patent number: 8201035
    Abstract: Testing system capable of detecting different kinds of memory faults of a memory under I/O compression includes a data pattern selection circuit, writing pattern selection units, reading pattern selection units, and a data comparison circuit. The data pattern selection circuit converts a testing data into different data patterns by the writing pattern selection units and accordingly writes to the corresponding memory data ends in order to allow the corresponding memory cells to store the data with the corresponding data pattern. The data comparison circuit executes reverse-converting through the reading pattern selection units for comparing if the data stored in the memory cells corresponding to each memory data end are matched and accordingly determines if a failure memory cell exists in the memory.
