active illumination การใช้

• The purpose of using active illumination sources is primarily to make the signal-to-noise ratio better.
• In technical and scientific terms, however, the active illumination schemes are safe according to all current legislation and standards.
• Such systems typically use infrared cameras, sometimes combined with active illumination techniques, to collect information that is then displayed to the driver.
• Active illumination couples imaging intensification technology with an active source of illumination in the near infrared ( NIR ) or shortwave infrared ( SWIR ) band.
• DaimlerChrysler has also taken the " active illumination " approach, building an infrared system that, like Visteon's, sends out an infrared beam, rather than just detecting infrared radiation from heat-emitting objects.
