摘要： Disclosed herein are systems and related methods for reducing speckle on display screen. More specifically, screen vibration is used to reduce speckle, and in accordance with the disclosed principles, the vibration may be achieved by using wave-based actuation (e.g., acoustic or electromagnetic waves) to vibrate the screen. In an exemplary embodiment, a speckle reducing system may comprise at least one actuating element located proximate to, but not in physical contact with, a display screen. In addition, the at least one actuating element may be configured to generate waves directed towards the display screen. When the waves impact the display screen, the waves impart vibration to the display screen.

摘要： Disclosed herein are techniques for the reduction speckle of a projection display system using novel lenslet integrators and related methods. In one embodiment, a lenslet integrator system for reducing speckle on a display screen may comprise a first lenslet array configured to receive incoming light for use in displaying an image on a display screen. Specifically, the first lenslet array has motion sufficient to reduce speckle by averaging multiple speckle patterns across its array. Such an exemplary system may also include a second lenslet array configured to receive light that is roughly focused from the moving first lenslet array, due to the motion of the first array. In addition, such systems may also include an output lens configured to receive light focused from the second lenslet array for output from the system for illumination of the display screen.

摘要： The light energy necessary for the precure process is held by the RFID at the holographic memory. The controller acquires the light energy corresponding to the temperature of the recording position detected by the temperature sensor out of the precure information acquired by the RFID reader. The exposure time (light emitting time of LED) Te in the precure process is calculated based on the calculating equation Te (sec)=En (joule)/Pd (watt) from the energy En and the intensity Pd of light irradiated onto the recording position detected by the light detector.

摘要： A method is provided for manufacturing a holographic medium by recording holograms in transmission geometry, and applying a reflective layer to one side of the holographic recording material after recording is completed (alternatively, for example, the playback system may contain a reflective surface or mirror). For readout, the reference beam is incident to the media from a side opposite the reflective layer. This beam propagates through the media to the reflective layer on the opposite side, and is reflected back through the media for readout of the transmission hologram. The diffracted hologram signal also exits the media on the side without the reflective layer, where it can be recovered by a detector on the same side as the laser source. Alternatively, the readout reference beam is positioned so that the incident beam reads out the hologram, and both the reference beam and diffracted hologram are reflected back through the media.
摘要翻译：提供了一种通过记录透射几何形状的全息图来制造全息介质的方法，并且在完成记录之后将反射层施加到全息记录材料的一侧（或者，例如，重放系统可以包含反射表面或反射镜）。为了读出，参考光束从与反射层相对的一侧入射到介质。该光束通过介质传播到相反侧的反射层，并通过介质被反射回来，用于读出透射全息图。衍射的全息图信号也离开没有反射层的一侧的介质，其中它可以通过与激光源相同侧的检测器回收。或者，读出的参考光束被定位成使得入射光束读出全息图，并且参考光束和衍射的全息图都通过介质反射回来。
