Abstract
An imaging device of reduced size includes a housing, a sensor, a filter, and a metalens. The housing defines a receiving cavity and a through hole connected to the receiving cavity. The sensor, the filter, and the metalens are disposed in the receiving cavity. The sensor is used to receive far-infrared light of the incoming light and form an image according to the far-infrared light. The filter is used to allow the far-infrared light of the incoming light to pass through. The metalens includes a substrate and a metasurface structure. The substrate is between the through hole and the filter. The metasurface structure is connected to the substrate. The far-infrared light is used to refract the far-infrared light, thereby causing the far-infrared light to focus on the sensor after passing through the filter.
