More Information
Summary:The disclosed non-damage detection device for food and farm product based on laser tomography imaging technique comprises: a frame, a laser emission device, an objective table, a CCD arc detector, an interface circuit, and a computer to send command by software and control the device to emit fan-shape laser and adjust modulation system and align system to let the laser pass some section of target and achieve at the CCD detector. Wherein, the target is lifted slowly, a data acquisition module continual acquires data to send to the computer for image reconstruction, and pattern recognition software obtains the quality index.
