  • Patent number: 10908086
    Abstract: A signal processing method and a signal processing system are provided to convert optical or electric signals by an effective circuit to have an increased dynamic contrast and reduced noises. The signal processing system includes an analog signal processing module and a digital signal processing module. When an optical signal of an object-to-be-detected is strong, an image-to-be-detected is obtained by an analog signal processing method. When the optical signal of the object-to-be-detected is weak, the image-to-be-detected is obtained by a digital signal processing method after background noises are filtered out.
    Type: Grant

  • Patent number: 9696533
    Abstract: An optical image scanning component is suitable to receive a light provided by a light source of a microscope device and comprises a first scanning unit and a second scanning unit. The first scanning unit comprises a first scanning mirror rotated along a first direction as axis at a first resonance frequency. The second scanning unit comprises a second scanning mirror rotated along a second direction as axis at a second resonance frequency which is different from the first resonance frequency. The light is emitted to the first scanning mirror and reflected to the second scanning mirror, and the light is reflected by the second scanning mirror to be transmitted to an objective lens module of the microscope device.
