Infrared marked cards are a kind of magic marking deck, which is more practical than ordinary marked poker cards. They are marked by invisible ink according to the infrared optics.
They can’t be seen by naked eyes, invisible ink pen contact lenses, glasses that see invisible ink and barcode poker scanners, but they can be seen with IR camera.
Infrared Contact Lenses
Infrared contact lenses are a great way to see marked cards without having to wear glasses. They also help people with light sensitivity see better when lighting levels change from bright to dim, which is important for anyone who regularly uses their eyes at night.
These smart lenses are designed to block harmful UV rays and blue light that can damage the retina, making them ideal for protecting the health of your eyes. They can be used in combination with sunglasses to ensure that your eyes are always protected from harmful UV and blue light rays.
To make the device more user-friendly, we developed a new fabrication method that allows electronic components to be integrated onto the soft lens with no mechanical deformations required for normal use. This means that the glucose sensor, LED pixel and rectifier circuit are fully integrated into the soft lens without a visible connection to the device. This makes the lens suitable for continuous, wireless monitoring of physiological conditions and for the detection of biomarkers associated with ocular diseases.
Infrared cameras detect infrared radiation and send the readings to a signal-processing unit, which then translates the information into data that is displayed on a monitor. Different colors are used to represent different temperatures, and these can be chosen and assigned to specific objects within the image.
This can be useful when identifying and repairing issues such as water leaks or air intrusion/lack of insulation. You can also link these cameras with other elements of a home security system to help prevent intruders from breaking in.
MWIR (mid-wave infrared) thermal imaging cameras use an Indium Antimonide (InSb) detector which is exclusively cryogenically cooled. This enables them to take thermal measurements quickly, allowing integration times as low as msec.
Infrared ink is an important component in the anti-forgery printing process. It can be applied to various types of cards such as RMB notes, gas vouchers and airline tickets.
The infrared marking inks are made up of a mixture of dyes, each having different absorption wavelengths. This makes the inks highly visible to scanners with varying sensitivities.
Another infrared marking ink uses microscopic particles (known as taggants) that react when a reader or verifier uses a UV or infrared light of a specific wavelength. This makes it easier for a scanner to determine whether or not the inks are genuine.
Infrared marked cards are easy to detect with the use of a professional LS108A or LS108D Linshang lens transmission meter. These instruments can measure transmittance at 550 nm for the visible inks and at 850 nm for the infrared inks.
Researchers have developed a new technology that can convert infrared light to visible images. They hope that this will eventually lead to night-vision goggles that are as simple to wear as sunnies.
The team used meta-surfaces, or thin films, to transform infrared waves into images that are easily seen. The resulting films can be 500 times thinner than a human hair and are made from aluminium, gallium and arsenide.
They are able to do this because they can reflect infrared light. This is the same principle as how glass reflects sunlight.
They could also be used in medical devices, anti-counterfeit technology in bank notes and imaging cells for military hardware. They are also cheap, lightweight and easy to produce.
