Abstract: Disclosed is an electronic device that is detachably coupled to a frame of a head-mounted device that can be mounted on a head of a user. The electronic device can consecutively perform tracking of the user's head using a sensor, when sensor data is abnormally received. Thereafter, if the sensor data is normally received from the head mounted device, the electronic device can consecutively perform the head tracking, enabling the user's action and the visual information to coincide with each other, thereby reducing inconvenience or misoperation which may occur in the case of the conventional head-mounted device.

Abstract: An image sensor includes an optical sensor layer including a plurality of light-sensitive cells configured to sense light to generate electrical signals, and a color filter array layer disposed on the optical sensor layer and including a plurality of color filters respectively facing the plurality of light-sensitive cells. Each of the plurality of color filters includes a nanostructure in which a first material having a first refractive index and a second material having a second refractive index higher than the first refractive index are arranged. The first material and the second material are alternatively positioned at an interval less than a central wavelength of a color of the color filter. Thus, a thin image sensor having good wavelength selectivity and suitable for obtaining high resolution images is provided.

Abstract: An on-chip optical filter having Fabri-Perot resonators and a spectrometer may include a first sub-wavelength grating (SWG) reflecting layer and a second SWG reflecting layer facing each other. A plurality of Fabri-Perot resonators are formed by the first SWG reflecting layer and the second SWG reflecting layer facing each other. Each of the Fabri-Perot resonators may transmit light corresponding to a resonance wavelength of the Fabri-Perot resonator. The resonance wavelengths of the Fabri-Perot resonators may be determined according to duty cycles of grating patterns.
