Abstract: An eye wear comprises an optical filter disposed in front of an eye. The optical filter has a transmittance function of wavelength comprising a transmittance peak having a peak transmittance and a transmittance bandwidth. A transmittance outside the transmittance peak is at a lower level transmittance, wherein a ratio of the lower level transmittance to the peak transmittance is less than unity. The transmittance peak is at a central wavelength of a laser that emits laser light forming one of a laser spot and a laser line. The transmittance bandwidth is larger than a bandwidth of the laser light emitted by the laser. The laser spot or the laser line formed by the laser light emitted by the laser is viewed through the eye wear.

Abstract: A 3D imaging system comprises a phase detection autofocus (PDAF) image sensor, a lens for imaging a cross-section of a 3D object on the PDAF image sensor and an actuator for driving the lens for focusing each cross-section of the 3D object on the PDAF image sensor. The actuator drives the lens until the PDAF image sensor identifies an image of a first cross-section of the 3D object in-focus and records the image of the first cross-section. The PDAF image sensor records images of subsequent cross-sections of the 3D object formed by the lens driven by the actuator on the PDAF image sensor. The recorded images of each cross-section of the 3D object are stacked to form a 3D image of the 3D object.

Abstract: A disposable micro-prism test chip for surface plasmon resonance measurement comprises a micro-tray and a micro-prism mounted on the micro-tray. The micro-tray and the micro-prism form at least one cell for providing a fluid dielectric medium for measurement. The disposable micro-prism test chip also comprises a thin metal layer coated on the surface of the micro-prism in the formed cell between the fluid dielectric medium and the micro-prism. The micro-tray may have at least one through window for forming the at least one cell. The micro-tray may also have a half-through cavity facing the micro-prism. The disposable micro-prism test chip is disposed after at least one use. The micro-prism may be fabricated by pulling a heated preform, where the preform has the same cross-section as that of the pulled micro-prism.

The fluorescence sample is to be positioned an object distance away from the lens. The lens is positioned an image distance away from the image sensor. The image distance is greater than the object distance. An illuminating device is disposed between the fluorescence sample and the lens. The illuminating device includes a light source and an optical element. The light source is adapted to emit light in a first direction towards the optical element. The optical element is optically coupled to receive the light and redirect the light in a second direction towards the fluorescence sample to illuminate the fluorescence sample.

Abstract: A laser aligning device is mounted on the flat side of a putter grip or other cylindrically asymmetric surface of a club grip and emits a fan shaped light sheet. The light sheet is perpendicular to the flat side of the putter grip. The light sheet projects a visible laser line on a plane such as the ground when the head is on the same plane. The alignment of the grip relative to the putter head's face can be inspected by visually inspecting the orientation of the projected line on the plane relative to the head's face. The grip can be adjusted and fixed so that it is properly oriented to the face.

Abstract: For magnifying a display of a portable device, the display is placed at a distance less than the distance of the normal near point to the eye (about 25 cm). However, the image will be blurred since the eye cannot focus the image onto the retina. To form a magnified image onto the retina, a positive lens is added in front of the eye. With a positive lens in front of the eye, and the device is placed closer than the near point to the eye, a viewer can see clearly the magnified display. A 2.5? (6.25 cm) display will be seen like a 32? (80 cm) display or even larger.

Abstract: A display magnifier for digital cameras is removably mounted to a camera using a screw tightened into a standard threaded tripod hole under the camera. A photographer views the display through the magnifier. When it is not in use, the magnifier can be folded for saving storage space and ease in carrying. The magnifier will not only magnify but also brighten since the magnifying lens will collect more light than the naked eye. Additionally, the screw may have a threaded hole in its head to allow the tripod screw to mate with it.

Abstract: A training putter with a laser line projecting device can be used for putting training to improve putting skill. The device is affixed to a putter head above its sweet spot, and emits a vertical light fan which projects a line on the around normal to the face of the putter head. The line is aligned with the sweet spot of the putter head and lies on the ground to connect the top of a golf ball with a target, such as a cup or a putting hole, so that alignment can be easily visualized. The device can be detached and reattached easily without any laser alignment. Furthermore, the device can be removably mounted to a user's own putter. The heat generated in the laser diode is quickly dissipated through the metal housing, the metal putter head, and the metal shaft to the surrounding air. Since proper operating temperature of the laser diode can be maintained, the laser diode will operate properly, which means the power of the emitted light will not be decreased, and the lifetime of the diode will not be shortened.
