There are many applications of infrared radiation. A number of these are analogous to similar uses of visible light. Thus, the spectrum of a substance in the infrared range can be used in chemical analysis much as the visible spectrum is used. Radiation at discrete wavelengths in the infrared range is characteristic of many molecules. The temperature of a distant object can also be determined by analysis of the infrared radiation from the object. Radiometers operating in the infrared range serve as the basis for many instruments, including heat-seeking devices in missiles and devices for spotting and photographing persons and objects in the dark or in fog.
infrared radiation (in-fruh-red)
radiation is often linked to heat, since objects at room temperature or above will emit radiation mostly concentrated in the mid-infrared band (see black body).
The common nomenclature is justified by the different human response to this radiation (near infrared = the red you just cannot see, far IR = thermal radiation), other definitions follow different physical mechanisms (emission peaks, vs. bands, water absorption) and the newest follow technical reasons (The common silicon detectors are sensitive to about 1050 nm, while InGaAs sensitivity starts around 950 nm and ends between 1700 and 2200 nm, depending on the specific configuration). Unfortunately the international standards for these specifications are not currently available.
Night Vision
Infrared is used in night-vision equipment, when there is insufficient visible light to see an object. The radiation is detected and turned into an image on a screen, hotter objects showing up brighter, enabling the police and military to acquire thermally significant targets, such as human beings and automobiles.
Smoke is more transparent to infrared than to visible light, so fire fighters use infrared imaging equipment when working in smoke-filled areas because it does not interfere with other devices in adjoining rooms - this is especially important in areas of high population density (IR does not penetrate walls).
Other Imaging
In infrared photography, infrared filters are used to capture only the infrared spectrum. Digital cameras often use infrared blockers. Cheaper digital cameras and some camera phones which do not have appropriate filters can "see" infrared, appearing as a bright white colour (try pointing a TV remote at your digital camera). This is especially pronounced when taking pictures of subjects near bright areas (such as near a lamp), where the resulting infrared interference can wash out the image.
Thermography
Infrared radiation can be used to remotely determine the temperature of objects (if the emissivity is known). This is termed thermography, or in the case of very hot objects in the NIR or visible it is termed pyrometry. Thermography (thermal imaging) is mainly used in military and industrial applications but the technology is reaching the public market in the form of infrared cameras on cars due to the massively reduced production costs.
Far Infrared Rays are invisible band of light
warms objects without warming the air between the source and the object (known as conversion). This radiant heat can also be called Infrared Energy (IR). This band of light is not visible to human eyes but can be seen by special instruments that translate infrared into colors that are visible to our eyes. The best example of Infrared Energy is the sun (80% of the sun’s rays are infrared). Our atmosphere allows IR rays in the 7 to 14 micrometre range to safely reach the Earth’s surface. When warmed, the Earth radiates infrared rays with its peak output at 10 micrometres. The human body radiates infrared energy out through the skin at 3 to 50 micrometres, with most around 9.4 micrometres.) and to remove ice from the wings of aircraft (de-icing).
Communications
IR data transmission is also employed in short-range communication among computer peripherals and personal digital assistants. These devices usually conform to standards published by IrDA, the Infrared Data Association. Remote controls and IrDA devices use infrared light-emitting diodes (LEDs) to emit infrared radiation which is focused by a plastic lens into a narrow beam. The beam is modulated, i.e. switched on and off, to encode the data. The receiver uses a silicon photodiode to convert the infrared radiation to an electric current. It responds only to the rapidly pulsing signal created by the transmitter, and filters out slowly changing infrared radiation from ambient light.
Just for reference tewa, these are the areas of ceramics technology I worked with. My brother is really heavy into it now. He gets a big kick out of using the system in buildings because he can detect when a person burps or farts. That's right, he has scientific proof that women fart! He can even identify a habitual and prolific farter and a dangerously powerful one. It is a big joke with them that the guys who decide who to hire always look at the emissions reports before deciding to hire someone.
In fact, he has to be able tell if it was a fart or some other type of gas emission just by using FIR and ferroelectric/piezoelectric ceramic sensors. He has to give account for every type of gas or heat source that is in the facility or it's dutcwork and identify it's chemical makeup. He also has to write the computer programs that keep records of it all and automatically send off different alerts and warnings. He also uses the communications uses of it to be able to keep the security aspects running and monitor them with all the power off.
That is why when folks ask if BH can do what it says my response is, "Of course it can!" In fact what BH claims is really nothing in comparison to what some ceramics are doing.
Just look at the results, they speak for themselves.
In terms of the issue of electromagnetic fields, I can think of at least four different ways off of the top of my head the energy required to accomplish that could be occuring just using basic ferro or piezoelectric powders and materials (ie porous flexible foam). If it is utilizing the piezoelectric field the way I suspect, it would explain why bh works so much better in a shower than it does immersed even with heavy oxygen. The friction theory, in my mind, is the least likely of the four options I am thinking of.
I have also contacted a friend who is willing to run some tests on it for us, but it cannot happen for a few months due to his situations. I will let you know as soon as it does buddy. He is on vacation for a month right now, and will need some time to catch up when he gets back.
I will also have to get legal permission from Momotaro to share that type of information about their product. Some of it they may not want out, not to hide anything, but to keep possible competitors from making the same thing or something too similar. I will email them and ask before publicly posting anything.
Also, I am going to keep away from pms too much with you so we do not get accused of some corporate conspiracy or marketing evil. I will just post it out here for everyone to read.
