The optical system includes a projector, a deflector, a polarizer, a first grating coupler structure, and a second grating coupler structure. The projector emits three beams having different wavelengths. The deflector is disposed below the projector and is configured to change incident angles of the three beams and to focus the three beams at the same region of the first grating coupler structure. The first grating coupler structure is below the deflector and is configured to couple the three beams into a light-guide lens such that the three beams travel the same optical path within the light-guide lens. The light-guide lens is connected to the first grating coupler structure and is configured to transmit the three beams. The polarizer is disposed between the projector and the deflector and is configured to filter out transverse electric (TE) modes or transverse magnetic (TM) modes of the three beams.

Optical imaging device

A micro light-emitting diode (LED) display panel is provided. The micro LED display panel includes a substrate and a driving layer. The driving layer is disposed on the substrate. The driving layer includes a micro LED and a photo sensor. When the micro LED emits light to a finger of a user, the photo sensor generates a sensing signal.

Micro light-emitting diode display panel, micro light-emitting diode display device, and fingerprint identification method

An optical fingerprint sensor, includes: an image sensor array; a collimator layer disposed above the image sensor array, the collimator array having an array of first apertures; a light guiding layer disposed on the collimator layer; a light source emitting light into the light guiding layer; and a sensing area disposed above the light guiding layer. The light guiding layer allows a portion of the light from the light source to enter to the sensing area while directing the remaining portion of the light forward.

Optical fingerprint sensor

An imaging apparatus includes a filter, a first image sensor and a second image sensor. The filter transmits a first light in a range of wavelengths and reflects a reflected light out of the range of wavelengths. An incident light is split to the first light and the reflected light. The first image sensor receives the first light to generate a first image signal. The second image sensor receives the reflected light to generate a second image signal.

Imaging capture apparatus having plurality of image sensors generating respective image signals based on emitted light areas

A solid-state imaging device is provided. The solid-state imaging device includes a substrate containing a plurality of photoelectric conversion elements. A color filter layer is disposed above the photoelectric conversion elements. A light shielding layer is disposed between the color filter layer and substrate. The light-shielding layer has a plurality of first light shielding partitions extended along a first direction and a plurality of second light shielding partitions extended along a second direction perpendicular to the first direction. The first light shielding partitions have different dimensions along the second direction and the second light shielding partitions have different dimensions along the first direction.
