Abstract: A concealment component for an optical sensor device includes an optical filter and one or more diffusive optical structures. The one or more diffusive optical structures are configured to distribute light in a diffused pattern on an input surface of the optical filter. The optical filter is configured to pass a first set of light beams, of the light distributed in the diffused pattern on the input surface of the optical filter, that are associated with a particular wavelength range, and prevent a second set of light beams, of the light distributed in the diffused pattern on the input surface of the optical filter, that are not associated with the particular wavelength range, from passing. Preventing the second set of light beams from passing is to cause the second set of light beams to be directed away from or absorbed by the concealment component in a concealment pattern.
