摘要： A measuring apparatus includes an irradiation device configured to irradiate an object with light; an imaging device configured to capture an image of the object irradiated with the light and generate captured image data; and circuitry. The circuitry is configured to measure the object based on the captured image data generated by the imaging device; and adjust, with a moving mechanism, relative positions among the object, the irradiation device, and the imaging device in response to a determination that the captured image data includes a region satisfying a predetermined condition.

摘要： Disclosed herein are systems and methods of use thereof. For example, disclosed herein are systems and methods for printing using superluminescent light. For example, disclosed herein are methods of printing with superluminescent light, the methods comprising: generating a patterned light sheet from superluminescent light, with the proviso that the superluminescent light is not generated by a femtosecond laser; and projecting the patterned light sheet at an image plane onto or within a sample comprising a photosensitive material; thereby simultaneously illuminating a selected portion of the photosensitive material within a layer of the sample corresponding to a selected pattern, thereby causing a simultaneous photoreaction that prints structures in the selected pattern.

摘要： Disclosed are light-curing printer display devices, 3-dimensional (3D) printers, control methods and devices, and electronic devices. In some embodiments, the light-curing printer display device include a screen, a light source assembly, a shielding plate, and a controller. In other embodiments, the light source assembly is arranged on a back side of the screen and the light source assembly includes multiple Light Emitting Diode (LED) light sources independent of each other. The shielding plate is arranged between the screen and the light source assembly and is provided with multiple light holes with the same number as that of the multiple LED light sources. The multiple light holes correspond to the multiple LED light sources one by one. The controller is electrically connected with the multiple LED light sources and is configured to control at least one LED light source to emit light.
