I am a graduate student working on the DLP Lightcrafter 4500 evaluation module. I am looking into the DMD chip in the DLP projector. I would like to know if there is a way to control individual pixels in the DMD or groups of pixels- in other words I would like to set a large majority of the DMD to the "off" position so that only a selected group of pixels or pixel can shine light. My application will be scanning a sample using the manipulated beam - preferably by only turning on pixels that I want to be measured in such a pattern that eventually will turn on all pixels 1 by 1 or group by group. I will eventually replace the LED lights with a laser and use to DMD setup in order to scan a sample and detect (either by transmission or reflection - not decided yet) into a single pixel detector. The software I am using is "DLPLCR4500 GUI 4.0.0" and I downloaded the software from the User Manual that came with the projector. To conclude, is there any way to control/cycle through individual pixels or group of pixels on the DMD to be set to "off" or "on" in an efficient and well controlled manner?
Welcome to DLP forum and thank you for your interest in DLP technology.
You can control the individual mirrors of the DMD using a 2 dimensional pattern. Since you want only on or off, you may want to consider using 1-bit patterns. The EVM support multiple method send these patters. .
Please refer to DLP4500 EVM user guide and and DLPC350 controller programmer's guide for details on patterns.

Thank you for your reply! I will look into 1-bit patterns and BMP image applications to complete this project.
