An imager assembly including calibration functionality and a housing. An imager is disposed inside the housing. The imager includes a lens assembly. An electro-optic element is disposed on a wall of the housing and operable between a substantially clear condition and a substantially darkened condition. A light source directs light at the electro-optic element which redirects the light toward the lens assembly.

Dynamic calibration of optical properties of a dimming element

An imaging assembly for use in a vehicle is disclosed. The imaging assembly may include an image sensor configured to capture image data and an electro-optic element configured to selectively control a range of wavelengths corresponding to light in a near infrared (NIR) range of light entering the image sensor. The electro-optic element may include a first portion configured to absorb the range of wavelengths entering the image sensor and a second portion configured to absorb the range of wavelengths entering the image sensor in a first state and to transmit the range of wavelengths entering the image sensor in a second state. The second portion may be electrically isolated from the first portion. A controller may be in communication with the image sensor and the electro-optic element. The controller may be operable to switch the second portion between the first state and the second state.
