Other Parts Discussed in Thread: DLPC2607,
I've been interested in applying TI digital micromirror devices for spectroscopic purposes (digital filtering, this has been an area of growing interest in spectroscopy for over a decade). This application requires rapid cycling through a limited series of 1-bit (black and white) patterns, typically stored in a buffer, and removed the LEDs and projection optics. It's basically running the light path backwards, with light reflected off the DMD routed into two detectors, corresponding to pixels in "on" or "off". I'm aware that TI knows about this and makes an IR spectrometer, but that's not suited to my particular application. I have been able to successfully remove the optical engine from my WVGA DLP (608 x 684 pixels, the original Lightcrafter), there's some help available on this topic on the internet. Yes, I'm aware that trying to do this on this unit will void the warranty, but at 99 bucks, that's an easy risk to take, and this unit has the micromirror on the end of a ribbon cable, making it easy to integrate it optically. On my earlier Lightcrafter there were detailed specs about the maximum frame rate I could achieve, including in monochrome mode. Since the local Linux processor was part of that unit, and it had internal pattern capability, it's clear why this could be specified in detail. I'm sure the max frame rate may be limited by what controller I'm using this with, so let's suppose I'm using a BeagleBone Black (ver C). Would you folks have any idea about the monochrome frame rates achievable here are, if in fact, monochrome can be done at all? Since I'm not planning on using this for DLP purposes, it's the monochrome (1-bit) performance that concerns me most, and I'd like to try something similar with this unit. I can find information about nHD line rates in the DLP2607 documentation (48 kHz in landscape mode), but I've found nothing about using this as a monochrome display. The power handling and wavelength capabilities of the mirrors are plenty adequate; the light is visible and level is extremely low compared to projection). Am I simply too far out of the box in trying to do that with this unit?
