ELB night vision

The ELB Night Vision Prototype 85 display

Night vision is the ability to see in low light conditions. Humans have poor night vision compared to many animals. The human eye lacks a tapetum lucidum, the layer of tissue behind the retina that reflects visible light back inward, increasing the light available to the photoreceptors.

Humans use technology to enable night vision such as image intensification which magnifies received photons from various natural sources such as starlight or moonlight, active illumination which couples imaging intensification technology with an active source of illumination in the near infrared or shortwave infrared band, and thermal vision which detects the difference in temperature between the background and foreground objects.

The ELB Night Vision Prototype 85 was a prototype helmet developed by Emmett Brown in 1991. It allowed the DeLorean time machine to be driven in the dark, without using headlights, by employing night vision technology.

When Verne Brown traveled to February 11, 1864, he arrived at night. As he didn't have the headlights on, the helmet of the ELB Night Vision Prototype 85 lowered over his head. This frightened Verne, and he crashed into the camp of Confederate General Beauregard Tannen.
