8.3 Typical Mobile Sensing Application

A typical embedded system application using the DLPC150 controller and the DLPC2010NIR is shown in Figure 43. In this configuration, the DLPC150 controller supports a 24-bit parallel RGB input, typical of LCD interfaces, from an external source or processor. The DLPC150 controller processes the digital input image and converts the data into the format needed by the DLP2010NIR. The DLP2010NIR steers light by setting specific micromirrors to the on position, directing light to the detector, while unwanted micromirrors are set to the off position, directing light away from the detector. The microprocessor sends binary images to the DLP2010NIR to steer specific wavelengths of light into the detector. The microprocessor uses an analog-to-digital converter to sample the signal received by the detector into a digital value. By sequentially selecting different wavelengths of light and capturing the values at the detector, the microprocessor can then plot a spectral response to the light.
