I want to use DMD to make single pixel imaging with DLP4500NIR.
Now, I use the DMD as a second screen with HDMI. After the DMD displays the bitmap of 1bit-depth , the detector detects the light intensity.
1.As a test, I made a 1140*912 bitmap with all 1 value and display a second monitor on Full Screen mode .
When I see the intensity graph (please, see the red line of the attached images) , Sometimes the value increases rapidly.
I don't know why. And Could you tell me the way to fix them?
2.A similar question as no1. I made the bitmap with 0 or 1 and then used the detector to capture its signal intensity.
But I could not get a stable values. Was that caused by video mode setting? What is the best way to display the 1bit-deapth bitmap image?
