Infrared radiation (IR), or infrared light, is a type of radiant energy that's invisible to human eyes but that we can feel as heat. All objects in the universe emit some level of IR radiation, but two of the most obvious sources are the sun and fire.
Adaptive infrared retinoscopic device for detecting ocular aberrations
An ocular system for detecting ocular abnormalities and conditions creates photorefractive digital images of a patient's retinal reflex. The system includes a computer control system, a two-dimensional array of infrared irradiation sources and a digital infrared image sensor. The amount of light provided by the array of irradiation sources is adjusted by the computer so that ocular signals from the image sensor are within a targeted range. Enhanced, adaptive, photorefraction is used to observe and measure the optical effects of Keratoconus. Multiple near-infrared (NIR) sources are preferably used with the photorefractive configuration to quantitatively characterize the aberrations of the eye. The infrared light is invisible to a patient and makes the procedure more comfortable than current ocular examinations.

An imaging device that includes a control unit is provided. The control unit switches between a day mode and a night mode. In the day mode, image capture is performed while an infrared cut filter is placed on an optical path, and in the night mode, image capture is performed while the infrared cut filter is removed from the optical path. Immediately after shifting from the day mode to the night mode, in the night mode, as the amount of incident light decreases, the control unit increases an irradiation intensity of an infrared irradiation portion from zero while a gain is maintained at a first gain value. When the amount of the incident light further decreases after the irradiation intensity reaches a maximum, the control portion increases the gain from the first gain value.

An authentication-enabled indicium contains authentication information in a digital recording medium. The information may be a digital signature that verifies the manufacturer's data and / or an analog signature. The analog signature is generated by placing a randomized pattern on a product package or label and encoding information about the randomized pattern in the digital recording medium for verification. The randomized pattern may be made up of color-shifting features imbedded in the label that are visible when illuminated with UV or infrared light. Characteristics of the reflected light when the features are illuminated is used to generate an analog signature that is encoded in the recording medium. During processing the features are illuminated and a new analog signature is determined for comparison with the signature recorded in the digital recording medium.
