Abstract
A detecting device and a detecting method thereof and a detecting apparatus are provided. The detecting device includes a stage, a light detection unit and a first, light, source, the stage includes a bearing surface for bearing an object to be detected, the light detection unit is located on a side of the stage, the first light source is located on a side of the stage that is opposite to the light detection unit, and light emitted from the, first light source is at least partially emitted to the light detection unit.
Claims14
A detecting device, comprising:
- a stage, including a bearing surface for bearing an object to be detected;
- a light detection unit, located on a side of the stage;
- a first light source, located on a side of the stage that is opposite to the light detection unit,
- wherein light emitted from the first ht source is at least partially emitted to the light detection unit,
- wherein the light detection unit includes:
- a light sensor array, including a plurality of light sensors, each of the plurality of light sensors is a photoresistor;
- the object to be detected includes a first illuminated region illuminated by the first light source;
- and an orthogonal projection of the light sensor array on a plane where the object to be detected is located at least partially overlaps with the first illuminated region;
- wherein the light detection unit further includes:
- a signal detection unit, being in signal connection with the light sensor array and configured to detect a resistance value of each of the plurality of photoresistors, to detect an intensity of light emergent from the object to be detected,
- wherein the detection device further comprises:
- a control module, being in signal connection with the light detection unit and configured to judge whether there is a defective region in the object to be detected according to a detection result of the signal detection unit,
- wherein the control module is configured to judge whether a resistance value of each of the photoresistors is an abnormal resistance value according to the detection result, to determine whether there is the defective region in the object to be detected.
