Title: DEFECT DETECTION DEVICE OF COMPACT CAMERA INTEGRATED MODULE
Abstract:
Provided is a defect detection device of a compact camera integrated module that detects a defect of a compact camera integration module by distributing a low-coherence beam or a high-speed wavelength variable beam to a sample stage for scanning the compact camera integrated module sample and a reference stage for acquiring image information of the sample, respectively, generating an interference signal using a sample signal and a reference signal that are respectively obtained from the sample stage and the reference stage, and converting the interference signal into an image and evaluating the image. As such, it is possible to quickly and efficiently detect whether or not a compact camera integrated module is defective.
