1. A binocular device for visualizing optical radiation, comprising
a support structure;
a left camera and a right camera coupled to the support structure, the left camera comprising left input optics and a left image sensor, the right camera comprising right input optics and a right image sensor, the left image sensor and the right image sensor being configured to create left and right video signals from detected optical radiation received from the corresponding left and right input optics about a same field of view along respective left and right input optical axes;
the device further comprising a processing unit configured to:
receive a signal representing a left image from the left camera and a right image from the right camera, the left image and the right image being captured substantially simultaneously by the left camera and the right camera, respectively;
compare the left image to the right image; and
detect a specular reflection based on a result of the comparison.
