Abstract
An inspecting system (100) includes a stage (10), a white light source (20), a CCD camera (40), a laser diode assembly (60), at least one beam splitter (36, 34), a photo diode (50), and an oscilloscope (52). The white light source emits a white light (22) to illuminate a color filter (200). The CCD camera photographs the color filter and is linked with an image processing and displaying device (42). The laser diode assembly emits a laser light (62). The at least one beam splitter is arranged in a path of the laser light and transmits the laser light to the color filter. The photo diode receives the laser light reflected by the color filter and generates an electronic signal. The oscilloscope is connected with the photo diode and displays the electronic signal. The inspecting system facilitates the convenient and accurate inspection/evaluation of color filters.
