Abstract
An optical structure is provided. The optical structure includes a sensor, a bandpass filter and a plurality of protrusions. The bandpass filter is disposed above the sensor. The protrusions are disposed on the bandpass filter. The bandpass filter allows light with a wavelength of 700 nm to 3,000 nm to pass through. The protrusions have a size distribution that controls the phase of the incident light to be between 0 and 2π.
