Video sensor VGAsens
Video sensor VGAsens
VGAsens is a photometric discrete light level sensor with digital TTL compatible1TTL (transistor-transistor logic) - specification of electrical interfaces of transistor-transistor digital logic. open collector output, pluggable analog voltage integrator and adjustable sensitivity range.
VGAsens is intended for use as part of systems that require synchronization of the image presentation on the screen of an electron beam or liquid crystal active-matrix monitor with other data streams, for example, an electroencephalogram.
It is recommended to use VGAsens with NVX series EEG amplifiers (MCS).
VGAsens allows you to detect the excess of the intensity threshold of the glow of a small area on the display (light spot) and changing the state of the TTL output to a high level. The state change is registered by an external device and used for synchronization with other data streams.
