  • Patent number: 10564264
    Abstract: The disclosure relates to a detection light ranging apparatus and method. The detection light ranging apparatus of the disclosure comprises: a detection light emitting circuit that emits detection light; a first optical assembly that divides the detection light into a first sub-detection light and a second sub-detection light; a second optical assembly that receives the second sub-detection light and causes the second sub-detection light to be emitted after being reflected at least once after being reflected by the measured object; and a timing circuit that receives the first sub-detection light and starts timing to obtain a first time, and receives the second sub-detection light emitted after being reflected at least once and finishes timing to obtain a second time. The detection light ranging apparatus of the disclosure can solve the technical problem of poor measuring precision of the prior ranging apparatuses.

  • Patent number: 9689807
    Abstract: A substrate detection device and a substrate direction method are disclosed in the embodiments for achieving a wide-range high-compatibility detection of leads in a peripheral circuit region of a liquid crystal display. The detection device comprises a converting unit configured to calculate a gray scale of a gray image of a circuit lead region of a substrate based on the gray image of the circuit lead region of the substrate, and to convert the gray image into an image of leads in the circuit lead region, based on a difference between the calculated gray scales of the leads and of the substrate in the circuit lead region; and a judging unit configured to judge a state of the leads in the circuit lead region based on the image of the leads in the circuit lead region.
