I need to present a series of images in rapid succession how do I check a different image is presented on every frame?
Pre-prepare two or more images with 16×16 pixel white reference blocks superimposed on them. On each image the reference block should be at a different location. You should place a black reference block at the position where the other image has the white reference block. Set the background of your experiment to black (this helps the sensors detect images for testing purposes). Attach two or more opto-detectors over where the reference blocks will appear. Run DSC (Digital Stimulus Capture) on your host PC. Now capture a sequence of presentations. When your capture is complete use the data analyser to check whether stimulus images appeared on alternate frames as intended.
