How Do Pro Laser Cameras Work?
Overview
Just as spy cameras are built to record activity in a surrounding area, a camera "catcher" uses laser beams to detect spy cameras in a home or office building or other public area to help stop or prevent unwanted recording of activity (called counter-surveillance devices). A camera detector finds the lens (twinkling light) of any camera (wireless, hard-wired, hidden or non-covert), and many can also find non-functioning cameras as well. The laser technology is built to refract around the camera lens, thus making it easier to detect hidden cameras up to 50-feet away. The pocket-sized devices operate on batteries.
Other Uses
Laser cameras are also used in medical technologies, including for the use of picture-taking of internal organs and tissues. They are also used in the use of pinpointing and applying certain specific treatments for various diseases and operating procedures to help eliminate surgically invasive techniques that cut down markedly on healing and recovery time.
Blooming and Flaring Mechanisms
Most cameras are imperfect machines and reflect and refract light by a blooming or flaring mechanisms. Blooming is when a camera's sensors are overwhelmed by larger sources of light, such as sunlight or candle light in the dark. Flaring happens because light bounces around the glass and metal inside of a camera. Because of these various blooming and flaring actions, it is possible to detect and disable cameras by the use of laser, a near-perfect monochromatic light source which emits a single wavelength (repetitious units in a given frequency range) and one (or sometimes several) pure colors.
Reflections of Light
Collimated light (light with nearly parallel rays) does not lose its brightness while traveling through empty space, so in a clear space, small bright spots from well-collimated lasers will travel for hundreds of feet or meters. Solid-state technology which was responsible for the replacement of vacuum tubes in computers with chips is the same kind of technology that allows lasers to work. Wavelength and color blends together to form radiation, which the human eye cannot see outside what is called the visible spectrum. Within the visible spectrum, where the naked eye can see visible light, the wavelength ranges between 400 and 700 nanometers with a color range of violet, blue, green, yellow, orange and red. Ultraviolet rays have shorter wavelengths that result in a visible light that appears violet. Infrared wavelengths are longer and make red light visible. White light is a mixture of colors and black light is the total absence of light. Wavelengths that are too short or too long cannot be seen at all.
Heart of the Laser Beam
The heart of any laser is the actual lasing medium. In solid-state lasers, most of these mediums consist of crystalline hosts that hold mineral ions, such as synthetic ruby (red hued), synthetic garnet (purple hued) and vanadate (see Resources below) and also plain glass.
