What purpose

Overview

 

The system comes with an automated software that drives automatically the measure sequence from one level to all the other levels or from any level to any.

 

Direct regression of the temporal behaviors with different mathematical model is used to extract response time values and additional parameters related to the shape of the temporal behaviors (overdrive, underdrive…).

 

The instrument can also measure flicker amplitude accurately down to -75dB well below the level of sensitivity of the human eye.

 

The software can also compute Moving Picture Response Time features and deduce BEW and NBET parameters for any gray level.

 

The OPTIScope 200 R2 can be used at various distances from the display down to ~30cm.
