Patent number: 9992396Abstract: A lighting module which provides adjustably controllable illumination of a camera field of view of a camera module includes an adjustable collimator which can be adjustably positioned such that the emitted light beam is adjustably directed to illuminate various regions of various camera fields of view. The collimator can be adjusted via an actuator which adjustably positions the collimator relative to static components of the lighting module, including the light emitter. The light beam can be directed to illuminate a selected limited region of a camera field of view, based on identification of a subject within the limited region. The light beam can be adjustably directed based on user interactions with a user interface, including adjusting the light beam according to user-commanded beam angle, intensity, and direction. The light beam can be adjustably directed to illuminate a region according to different fields of view of different camera modules.Type: GrantFiled: February 2, 2015Date of Patent: June 5, 2018Assignee: Apple Inc.Inventors: Miodrag Scepanovic, Angelo M. Alaimo, Florian R. Fournier, Andreas G. Weber, Simon S. Lee

Publication number: 20180081093Abstract: An electronic device may have an optical system that includes one or more light-based components. The light-based components may include light-emitting components such as light-emitting diodes or lasers and may include light-detecting components such as photodiodes or digital image sensors. The optical system may include a light diffuser. The light diffuser may diffuse light that is being detected by a light-detecting component or may diffuse light that is being emitted by a light-emitting component. Light diffusers in optical systems may be formed from patterned light diffuser layers on transparent substrates. Layers of sealant, thin glass layers, antireflection coatings, and other layers may be incorporated into the light diffusers. The light diffuser layers may operate at visible wavelengths and infrared wavelengths. An infrared light diffuser layer may be formed from a patterned silicon layer such as a patterned layer of hydrogenated amorphous silicon.Type: ApplicationFiled: September 16, 2016Publication date: March 22, 2018Inventors: Ligang Wang, Miodrag Scepanovic, Neil MacKinnon, Zhenbin Ge

Patent number: 9894257Abstract: A light source module includes an array of illumination elements and a light diffusing material. The light source module is configured to receive a control signal for adjusting diffusion of light emitted from the light source module and in response adjust the amount of diffusion of light emitted from the light source module. A light source module may include a segmented light diffusing material where each segment is associated with an illumination element. And individual segments may have light diffusing properties that are different than other segments of the light diffusing material. Some illumination elements may emit light of a different color spectrum than other illumination elements, and a light diffusing material may scatter the different colored light to illuminate a scene with combinations of light of different colors. A light source module may be embedded in a mobile computing device.Type: GrantFiled: May 13, 2015Date of Patent: February 13, 2018Assignee: Apple Inc.Inventors: Florian R. Fournier, Angelo M. Alaimo, Simon S. Lee, Miodrag Scepanovic, Andreas G. Weber

Patent number: 9869847Abstract: An optical system for operation at a target near-infrared (NIR) wavelength in imaging an object onto an image plane. The system includes the following optical elements, arranged in order from object side to image side: a first lens, including a first material having a first index of refraction at the target NIR wavelength and having a positive refractive power; a second lens comprising the first material and having a meniscus shape; a third lens comprising the first material and having a meniscus shape; and a fourth lens, including a second material having a second index of refraction at the target NIR wavelength that is lower than the first index of refraction, and having front and rear surfaces of an aspheric form. The aspheric coefficients are chosen so that rays are not totally internally reflected within the fourth lens to impinge on the image plane.Type: GrantFiled: February 7, 2016Date of Patent: January 16, 2018Assignee: APPLE INC.Inventors: Miodrag Scepanovic, Yoshikazu Shinohara, Yuhong Yao

Publication number: 20170176249Abstract: Apparatus and methods are described, including an apparatus for testing a light beam emitted by a light source. The apparatus includes a transparent substrate, a first face of the substrate being shaped to define a plurality of optical deflectors. At least one optical detector is positioned to face a second face of the substrate that is not opposite the first face. Each one of the deflectors is configured to deflect a portion of the light beam toward the detector, when the light beam is passed through the first face of the substrate. Other applications are also described.Type: ApplicationFiled: December 21, 2015Publication date: June 22, 2017Inventors: Florian R. Fournier, Miodrag Scepanovic

Publication number: 20160225301Abstract: A device which includes a display can provide adjustable light output, based in part on the color of the display screen output, to control the light output of the display screen. An illumination processor can adjustably control light output based on the colors of portions of the display screen. The light output can be adjusted to maintain the light output of the display screen across a range of colors of display screen light output. Controlling the light output of the display screen results in controlling the illuminance of a subject. The device can include a camera which captures an image of the subject and displays the image on a portion of the display screen, where the light output of a portion of the display screen can illuminate the subject such that the captured image has at least a certain level of image quality.Type: ApplicationFiled: February 2, 2015Publication date: August 4, 2016Applicant: Apple Inc.Inventors: Miodrag Scepanovic, Angelo M.
