Spectratech OEG-16H is designed to simultaneously measure a change of the amount of blood in each in vivo part not so deep in by the multi-channel (up to 16 channels) method. It utilizes the light absorption characteristics in the neighborhood of near infrared to red light that changes with the bonding state of the in vivo hemoglobin (Hb) with oxygen. The spread spectrum modulation method that is the latest digital technique and originally developed by our company is adopted for the optical modem technology that underlies the equipment. It has achieved great reduction in costs, downsizing, and high performance compared with the conventional technologies. It is assumed that the equipment is used mainly on the frontal lobe part that has few hairs. So, a simple and non-invasive measurement is possible, and it is also considered to use it for a battery-powered mobile measurement system, and simultaneous measurements for multiple examinees.
 In addition, the equipment has been developed consistently for research purpose, so you are kindly requested not to use it for other purposes.
 The equipment can be used in stand-alone mode, or by connecting with PC with a USB port and Microsoft Windows 7 or 8 installed.

Note: This equipment is exclusively for the research purpose, so please do not use for any other purposes.
