Original Abstract Submitted

An optical sensing system includes an optical film and a transceiver configured to at least 5 one of emit and receive a first light toward an object through the optical film along a propagation direction making a first angle of greater than about 20 degrees in an air with a normal to the optical film. The first light has a first infrared wavelength in an infrared wavelength range extending from about 800 nm to about 2000 nm. For an incident light incident on the optical film in the air and having the first infrared wavelength and for at least one of mutually orthogonal first and second 10 polarization states, the optical film reflects at least 60% of the incident light at an incident angle of less than about 5 degrees, and transmits at least 40% of the incident light at an incident angle substantially equal to the first angle.
