Problems solved by technology
Even though this is not a problem in some optical systems, in coated systems a change in the index of refraction can cause a change in transmission
These changes can have a large impact when considering the many parametric detection systems making very fine-grained measurements

Description
technical field [0001] The invention relates to a parameter detection system, an infrared bandpass filter, a glass substrate for the infrared bandpass filter, and a parameter detection method. The system can be used, for example, to detect individual parameters such as iris recognition, 3D scanning, touch sensors, biometrics, interactive displays, games and gesture control. [0002] For the purposes of the present invention, a "parameter detection system" is generally an electronic system capable of measuring at least one parameter of at least one individual or subject. The measured parameter can be selected from any parameter that can be measured using optical methods. "Detection" includes the identification and / or quantification of various parameters. Background technique [0003] Gesture control devices, iris scanners and other related parameter detection devices are themselves prior art. These devices generally have an infrared light source (illumination unit) for ill...
