with DLP proector




The most widely used system to present a stimulus pattern is the reversal pattern that consists in presenting the light and dark elements of the pattern, bars or chess, so that alternately reversed each other's position (reversal), however without modifying the average luminance, without which the eye receives any flash.

The pattern stimulator is ideal for generating structured stimuli such as vertical bars, horizontal, check board.
This type of stimulation can be obtained by numerous techniques; the most practical and versatile is the one that uses a system consisting of an electronic generator connected to a display system which in this case is a LED DLP projector.

The system is composed of:
  • BM1610 module
  • LED DLP projector
  • table with electric adjustment
  • chin patient
  • projection screen with anti-reflective treatment
  • safety transformer for the supply of electrical components
