摘要： A prism rotation adjustment mechanism, a photolithographic exposure system and a photolithography tool are disclosed. The prism rotation adjustment mechanism includes a frame (200), a flexible mechanism (100) and an actuation mechanism. The flexible mechanism (100) includes a fixing component (110), an actuating component (120), a connecting component (130) and a swinging component (140) that are flexibly articulated in a sequence. The fixing component (110) is fixed to the frame (200). The actuation mechanism is fixed to the frame (200) and coupled to the actuating component (120). On the swinging component (140) are secured a prism wherein an axis of articulation between the swinging component (140) and the fixing component (110) is in correspondence with a rotational center of the prism. The flexible mechanism of the prism rotation adjustment mechanism is a quadrilateral flexibly-articulated assembly, in which, when driven by the actuation mechanism, the actuating component can convert translational movement into rotational movement, allowing the control of the rotational movement to be more accurate and hence improving the rotational control accuracy of the prisms. Moreover, the axis of articulation between the swinging component and the fixing component provides a stable axis for the prisms to rotate thereabout, avoiding crosstalk during the rotation and hence additionally improving the prism rotation control accuracy.

摘要： A component assembly includes a first component, such as an optical component, and a second component, such as a support component, having different coefficients of thermal expansion (CTEs). The component assembly also includes a spacer having a CTE matched to that of the first component, disposed between the first component and the second component. When the CTE of the first component is greater than that of the second component, the second component includes a protrusion, and the spacer includes a complementary opening for receiving the protrusion, such that a joint between the protrusion and the complementary opening is under compressive stress. The spacer also includes a mounting area for receiving the first component, and an air gap disposed between the first component and the protrusion.

摘要： The technology disclosed relates to enhancing the fields of view of one or more cameras of a gesture recognition system for augmenting the three-dimensional (3D) sensory space of the gesture recognition system. The augmented 3D sensory space allows for inclusion of previously uncaptured of regions and points for which gestures can be interpreted i.e. blind spots of the cameras of the gesture recognition system. Some examples of such blind spots include areas underneath the cameras and/or within 20-85 degrees of a tangential axis of the cameras. In particular, the technology disclosed uses a Fresnel prismatic element and/or a triangular prism element to redirect the optical axis of the cameras, giving the cameras fields of view that cover at least 45 to 80 degrees from tangential to the vertical axis of a display screen on which the cameras are mounted.
