Abstract
Disclosed is a LiDAR window integrated optical filter that includes a window of a polymer material for absorbing a visible light band and transmitting a near-infrared band; and an upper reflective layer and a lower reflective layer formed on the upper surface and the lower surface of the window. The upper reflective layer and the lower reflective layer may be formed in a thin film including titanium dioxide (TiO2) and silicon dioxide (SiO2).
Claims16
A light detection and ranging (LiDAR) window integrated optical filter, comprising:
- a window comprising a polymer material;
- an upper reflective layer formed on an upper surface of the window;
- and
- a lower reflective layer formed on a lower surface of the window;
- wherein the polymer material absorbs a visible light and transmits a near-infrared light,
- wherein each of the upper reflective layer and the lower reflective layer is formed in a film comprising titanium dioxide (TiO2) and silicon dioxide (SiO2).
A light detection and ranging (LiDAR) window integrated optical filter, comprising:
- a window comprising a polymer material absorbing visible light having a wavelength of about 350 nm to 780 nm;
- an upper reflective layer laminated on an upper surface of the window to reflect infrared light having a wavelength of about 1,400 to 1,600 nm;
- and
- a lower reflective layer laminated on the lower surface of the window to reflect infrared light having a wavelength of about 1,100 to 1,400 nm.
