  • Publication number: 20220350264
    Abstract: An exposure tool is configured to remove contaminants and/or prevent contamination of mirrors and/or other optical components included in the exposure tool. In some implementations, the exposure tool is configured to flush and/or otherwise remove contaminants from an illuminator, a projection optics box, and/or one or more other subsystems of the exposure tool using a heated gas such as ozone (O3) or extra clean dry air (XCDA), among other examples. In some implementations, the exposure tool is configured to provide a gas curtain (or gas wall) that includes hydrogen (H2) or another type of gas to reduce the likelihood of contaminants reaching the mirrors included in the exposure tool. In this way, the mirrors and one or more other components of the exposure tool are cleaned and maintained in a clean environment in which radiation absorbing contaminants are controlled to increase the performance of the exposure tool.

  • Publication number: 20220317465
    Abstract: A method for rendering data of a three-dimensional image adapted to an eye position and a display system are provided. The method is used to render the three-dimensional image to be displayed in a three-dimensional space. In the method, a three-dimensional image data used to describe the three-dimensional image is obtained. The eye position of a user is detected. The ray-tracing information between the eye position and each lens unit of a multi-optical element module forms a region of visibility (RoV) that may cover a portion of the three-dimensional image in the three-dimensional space. When coordinating the physical characteristics of a display panel and the multi-optical element module, a plurality of elemental images can be obtained. The elemental images form an integral image that records the three-dimensional image data adapted to the eye position, and the integral image is used to reconstruct the three-dimensional image.

  • Patent number: 11144194
    Abstract: An interactive stereoscopic display and an interactive sensing method for the same are provided. In the method, a gesture sensor senses a hand gesture over a stereoscopic image displayed on a stereoscopic display. The gesture is such as moving, rotating or zooming actions. The gesture is referred to, to obtain stereo coordinate variations that are used to determine an interactive instruction. Next, the stereoscopic display or a stereoscopic image server generates a new stereoscopic image data by comparing image coordinate data of the stereoscopic image with a previous state of image coordinate data according to the interactive instruction. The stereoscopic image data describes color and three-dimensional information of the stereoscopic image. Therefore, the stereoscopic display displays a new stereoscopic image using the new stereoscopic image data. The method achieves an interactive effect with the stereoscopic image using the gesture.
