  • Patent number: 10394020
    Abstract: An image forming apparatus includes a light scanning device, a light detection unit, and a positional-deviation-amount calculation unit. The light detection unit includes a slit-shaped first light detection region and a slit-shaped second light detection region arranged to have mutually different angles with respect to a scanning direction of the light beam, and outputs a detection signal when the light beam passes through each of the light detection regions. The positional-deviation-amount calculation unit calculates a time period until when the light beam passes through the second light detection region from when the light beam has passed through the first light detection region for each scan of the light beam based on the detection signal output from the light detection unit, and calculates a variation characteristic of a positional deviation amount in a sub-scanning direction of the light beam associated with rotation of the polygon mirror.

  • Patent number: 9761051
    Abstract: Technologies are generally described to display of an Augmented Reality (AR) image using a micromirror on an eyeglass. In some examples, AR data may be received at a controller coupled to a laser transmitter positioned on a surface of a frame of the eyeglass. The laser transmitter may transmit a laser signal modulated by the received AR data onto the micromirror positioned on, preferably, a proximal surface of a lens of the eyeglass. Concurrently, an electrical signal may be transmitted to a base of the micromirror causing the micromirror to oscillate in correlation with an intensity of the laser signal such that the AR image is created on a retina. In another embodiment, the laser signal modulated by the received AR data may be reflected from a plane mirror positioned on the proximal surface of the frame, forward to the laser transmitter, to transmit the laser signal onto the micromirror.

  • Patent number: 8710471
    Abstract: A projection illumination installation for EUV microlithography includes an EUV synchrotron light source for producing EUV used light. An object field is illuminated with the used light using illumination optics. The object field is mapped into an image field using projection optics. A scanning device is used to illuminate the object field by deflecting the used light in sync with a projection illumination period. The result is a projection illumination installation in which the output power from an EUV synchrotron light source can be used as efficiently as possible for EUV projection illumination.

  • Patent number: 8681399
    Abstract: This disclosure provides systems and methods for decoupling the mechanical drive systems of image scanners from the exposure system. A light source, such as an array of light-emitting diodes (LEDs), may be modulated in order to maintain a constant exposure for each scan-line, regardless of the document velocity. Accordingly, the present systems and methods allow for continuous document scanning at varying speeds. An automatic document feeder may dynamically adjust the velocity of a document without negatively impacting the exposure of the image scan. As the velocity of the document is changed, the modulation rate of the light source may be adjusted to maintain a constant exposure.

  • Patent number: 8670170
    Abstract: An optical scanning projection system includes a scanning light source component, a second reflecting element, a transparent element, a scanning element, a photosensitive element and a control module. The transparent element receives a main light beam emitted by the scanning light source component and reflects a part of the main light beam to be a reflected light. The reflected light is reflected by the second reflecting element, and the scanning element reflects the reflected light from the second reflecting element in a scanning manner. The photosensitive element receives the reflected light from the scanning element and outputs a sensing signal, and the control module actuates or stops actuating the scanning light source component according to the sensing signal. Therefore, when the scanning element is damaged, the control module may instantly stop actuating the scanning light source component, thereby enhancing the using safety of the optical scanning projection system.
