Provided are an optical device which is capable of optically implementing an activation function of an artificial neural network and an optical neural network apparatus which includes the optical device. The optical device may include: a beam splitter splitting incident light into first light and second light; an image sensor disposed to sense the first light; an optical shutter configured to transmit or block the second light; and a controller controlling operations of the optical shutter, based on an intensity of the first light measured by the image sensor.

An optical scanning device includes a light source configured to emit first light in a first wavelength range and second light in a second wavelength range, a beam divider configured to allow the first light to travel in a first direction, and receive the second light, and allow the second light to travel in a second direction different from the first direction, a first optical modulator configured to receive the first light, and modulate a phase of the first light received by the first optical modulator to change a travelling direction of the first light received by the first optical modulator, and a second optical modulator configured to receive the second light, and modulate a phase of the second light received by the second optical modulator to change a travelling direction of the second light received by the second optical modulator.

Optical scanning device and LIDAR system including the same

An in-situ coin cell includes a case, a cap coupled to the case, and an energy storage member disposed between the case and the cap, where a through hole is defined in at least one of the case and the cap, the energy storage member includes a current collector adjacent to the through hole, and another through hole is defined in the current collector. The in-situ coin cell may further include a transparent window between the current collector and at least one of the through holes.
