Subpixel Scatter in Digital Micromirror Devices
نویسندگان
چکیده
The DMD (Digital Micromirror Device) has become an integral part of the instrumentation for many applications. Prior characterization of this device has been focused on its use in DLP (TI Digital Light Processing) projector applications where a collimated wavefront impinges on the DMD. The results of such investigations are not applicable to using DMDs at the focal plane of an optical system where it is used as a slit mask (e.g. in a multi-object spectrometer). In order to study the DMD scattering function in this second case, a subpixel spot scanning system has been assembled. The scattered light collected from this system allowed a subpixel scattering function to be determined for the DMD when illuminated by a converging beam.

Scattered Light in a DMD based Multi-Object Spectrometer
The DMD (Digital Micromirror Device) has an important future in both ground and space based multi-object spectrometers. A series of laboratory measurements have been performed to determine the scattered light properties of a DMD. The DMD under test had a 17 m pitch and 1 m gap between adjacent mirrors. Prior characterization of this device has focused on its use in DLP (TI Digital Light Process...
متن کاملOptical Scatter Imaging with a digital micromirror device.
We had developed Optical Scatter Imaging (OSI) as a method which combines light scattering spectroscopy with microscopic imaging to probe local particle size in situ. Using a variable diameter iris as a Fourier spatial filter, the technique consisted of collecting images that encoded the intensity ratio of wide-to-narrow angle scatter at each pixel in the full field of view. In this paper, we r...
متن کاملFabrication of a Micromirror with Sidewall Electrodes
We designed and fabricated a micromirror with sidewall electrodes in the Cornell NanoScale Science & Technology Facility (CNF) for endoscopic application. The micromirror can perform 2-dimensional scanning. The static and dynamic performances of the micromirror are improved over that of a micromirror without sidewall electrodes. In addition, undesired spring-softening effect that is commonly fo...
متن کاملDesign of illumination and projection optics for projectors with single digital micromirror devices.
We present a new optical system design for a projector with a single digital micromirror device (Texas Instruments Digital Micromirror Device) that improves on previous designs in terms of optical efficiency, uniformity, and contrast while yielding a low-profile and compact system. A rod integrator is incorporated with a compact relay system to maximize light efficiency and to increase illumina...
متن کاملThe CAOS Camera Platform – Ushering in a Paradigm Change in Extreme Dynamic Range Imager Design
Multi-pixel imaging devices such as CCD, CMOS and Focal Plane Array (FPA) photo-sensors dominate the imaging world. These Photo-Detector Array (PDA) devices certainly have their merits including increasingly high pixel counts and shrinking pixel sizes, nevertheless, they are also being hampered by limitations in instantaneous dynamic range, inter-pixel crosstalk, quantum full well capacity, sig...
