Description

Technical Field

[0001] The utility model relates to the technical field of optical low-pass filters, in particular to an optical low-pass filter device. Background Art

[0002] In daily life, we often see interviewed guests on television programs wearing ties with cross-twill stripes, which creates a mottled effect when the camera captures the image. This phenomenon is caused by the camera generating moiré interference, resulting in unclear images. Moiré is a physical phenomenon that easily occurs when a circular or grid-like linear image is close to the spatial frequency of the CCD array. From a technical perspective, moiré is the visual result of interference between two lines or two objects at a constant angle and frequency. When the human eye cannot distinguish between the two lines or two objects, only the interference pattern is visible, and this optical phenomenon is called moiré. Existing moiré is achieved by utilizing the physical polarization properties of quartz to retain the direct portion of incoming light and reflect the oblique portion. However, since cameras typically only trim horizontal light, ultraviolet and infrared light within the camera can easily interfere with the image formed by the camera, resulting in false-color interference fringes within the color CCD optical system. Therefore, we have designed a new method. Utility Model Content
