Abstract
The system may include at least one a light emitter configured to emit light over a range of wavelengths onto an environment and at least one sensor assembly. The range of wavelengths emitted by the light emitter may be of wavelengths that are above or below wavelengths used by a night vision imaging system. The sensor assembly may include an image sensor and conversion layer. The image sensor may capture images of the environment illuminated by the light emitters and sense light in a given range of wavelengths. The conversion layer may receive the emitted light and convert the emitted light to converted light with a wavelength within the given range of wavelengths associated with the image sensor. The image sensor may be further configured to receive the converted light from the conversion layer, capture an image of the light emitter and output image data associated with the captured image.
