Heat-vision cameras have been used widely in many industries for decades: Soldiers find targets through heat-vision rifle sights, police mount them on helicopters to search for people on the ground and contractors use the sensors to look for cold air seeping into homes. Now you can buy a simple smartphone attachment to reveal the widely varying temperatures of the people and things around you.
Maybe youre not up for hunting Arnold Schwarzenegger, like the heat-seeing alien hunter in the classic 1987 film Predator. There are many practical home uses for the latest thermal camera accessories from Flir and Seek, too: finding your missing cat hiding in the dark under the porch, diagnosing a blocked pipe in your bathroom or seeing how much propane is left in your gas grills tank. These cameras also allow you to peer into a previously invisible thermal landscape, revealing surprising views of the world around you.
Much like any super power, there are limitations to this extrasensory ability. Glass is good at letting through visible light, but filters out the kind of infrared radiation we know as heat. What makes them good for windows makes them nearly opaque to heat-sensing cameras. These thermal cameras will show the temperature of the glass surface, but if someone is standing just behind the window (and not touching it), that person will remain largely invisiblethough you may see your heat reflected in the glass back at you. In fact, thermal cameras lenses arent made from regular glass, but require special materials such as germanium, which allow this range of infrared light to pass.

By chance it's not locked down so you can peruse it at your leisure.
I have FLIR One. It’s awesome.
I have a Nikon D-50 with the IR filter removed from the sensor. It takes cool faux-color daytime pics, night pics with a light source (to focus), but one thing it can do is tell if a car has had a section repainted... It may look normal in our spectrum, but you can’t fool IR :o)
Unfortunately, we may need such devices in the near future.
Someday this (thermal infrared heat detectors), combined with electrical activity detectors, may be used to really get into how the brain works, possibly even one day to ‘read minds’. Blood flow to various areas of the brain registers as heat, while electrical activity to parts of the brain can similarly be detected. Hook a subject up to both simultaneously and observe and map the regions of the brain where the blood flow and electrical activity are, as he/she responds to different things. Map the correlation between blood, electricity, and thoughts, and you might be able to use the detection technology alone to know what a person is thinking. In other words, pair it together.
The research into that is surprisingly advanced. I was watching a show where a subject viewed photos in one room while his brain generated (via electrical impulse) correlating words on a computer screen in another.
He viewed a picture of a Hawaiian beach scene and his brain generated words like sand, beach, hotel, palms
So should I make sure my tin foil hat is glass lined?
Laz uses one to find the “hot” women.
Which application(s) are you using it for, mostly? (If you don’t mind sharing :) Thanks.

There are many ways to look inside the brain without cutting it open, and each imaging technique has its pros and cons. The Laboratory of Neuro Imaging at UCLA has created a human brain atlas using data collected by the International Consortium for Brain Mapping from thousands of people.
The goal is to understand the relationship between brain anatomy and function, to see the complex connections between different brain regions, and to be able to tell the difference between normal and abnormal variability. In addition to building a fundamental understanding of the brain, this information can help in planning surgery, developing new medications, or monitoring and treating neurological disorders.

Some minds of course would likely be easier to read than others. :)
It may be possible to 'read' a persons memories just by looking at brain activity, according to new research. Scientists show that our memories are recorded in regular patterns, a finding which challenges current scientific thinking.

What we write online may be intercepted, filtered and publicized, but wed like to think that the thoughts and images in our heads are totally private.
For better or worse, science may change that. Over the last few years, researchers have made significant strides in decoding our thoughts based on brain activity.
How this would work is still at the very early stages of development. But, given what we can already do, its not a huge leap to imagine that one day we could read the words of peoples internal streams of thought, said Jack Gallant, a prominent neuroscientist at the University of California, Berkeley.
I think decoding the little person in your brain we could do that today if we had a good enough method of measuring your brain activity, Gallant said.
Gallant predicts that in 50 years, thought-reading will be commonplace. Well be wearing Google Hats, he envisions, that are continuously decoding our thoughts.
Such a wonder-cap might transmit and even translate our thoughts into foreign languages.
But Dr. Josef Parvizi, a Stanford University neurologist who also studies the relationship between brain and mind, is much more skeptical. ... (continues at link)

They can record your dreams and put it on a computer generated video. Blurry, but hey.
I’ve been looking at some of the products offered by a company called Torrey Pines Logic. Reviews are pretty solid and the prices are edging toward the acceptable range. The rigs they sell that look like small holosights are particularly interesting.
Would be interesting to ‘see’ what a blind-from-birth person dreams. If they never saw anything in their lives, what on earth goes on when they dream? How do they ‘visualize’ the world in their minds?
Sound, smell, touch. I recommended an art gallery for the blind but the art director kind of sneered at me. I love texture and it would be easy to do. Heat for red, cold for blue, etc.
But surely their brain generates images of some sort in their minds while thinking and sleeping.
They’ve been using the larger sized FLIR cameras on the Ghost Hunters tv show for years.
How well do snakes show up?
here’s 2 videos for ya. A blind man answering your question and the images they recorded during sleep..
