Micromirror Array Optical Characteristics

TI assumes no responsibility for end-equipment optical performance. Achieving the desired end-equipment optical performance involves making trade-offs between numerous component and system design parameters.

a Micromirror tilt angle DMD “parked” state(1)(2)(3), see Figure 13 0 degrees
DMD “landed” state(1)(4)(5)
see Figure 13
β Micromirror tilt angle tolerance(1)(4)(6)(7)(8) See Figure 13 –1 1 degrees
Micromirror crossover time(9) 4 µs
Micromirror switching time(10) 13 22 µs
Array switching time at 400 MHz with global reset(11) 43 µs
Non-operating micromirrors(12) Non-adjacent micromirrors 10 micromirrors
adjacent micromirrors 0
Orientation of the micromirror axis-of-rotation(13) See Figure 12 44 45 46 degrees
Micromirror array optical efficiency(14)(15) 400 nm to 700 nm, with all micromirrors in the ON state 68%
  1. Measured relative to the plane formed by the overall micromirror array.
  2. “Parking” the micromirror array returns all of the micromirrors to an essentially flat (0˚) state (as measured relative to the plane formed by the overall micromirror array).
  3. When the micromirror array is “parked”, the tilt angle of each individual micromirror is uncontrolled.
  4. Additional variation exists between the micromirror array and the package datums, as shown in the Mechanical, Packaging, and Orderable Information.
  5. When the micromirror array is “landed”, the tilt angle of each individual micromirror is dictated by the binary contents of the CMOS memory cell associated with each individual micromirror. A binary value of “1” will result in a micromirror “landing” in an nominal angular position of “+12°”. A binary value of 0 results in a micromirror “landing” in an nominal angular position of “–12°”.
  6. Represents the “landed” tilt angle variation relative to the Nominal “landed” tilt angle.
  7. Represents the variation that can occur between any two individual micromirrors, located on the same device or located on different devices.
  8. For some applications, it is critical to account for the micromirror tilt angle variation in the overall System Optical Design. With some System Optical Designs, the micromirror tilt angle variation within a device may result in perceivable non-uniformities in the light field reflected from the micromirror array. With some System Optical Designs, the micromirror tilt angle variation between devices may result in colorimetry variations and/or system contrast variations.
  9. Micromirror crossover time is primarily a function of the natural response time of the micromirrors and is the time it takes for the micromirror to crossover to the other state, but does not include mechanical settling time.
  10. Micromirror switching time is the time before a micromirror may be addressed again. Crossover time plus mechanical settling time.
  11. Array switching is controlled and coordinated by the DLPC410 (DLPS024) and DLPA200 (DLPS015). Nominal Switching time depends on the system implementation and represents the time for the entire micromirror array to be refreshed (array loaded plus reset and mirror settling time).
  12. Non-operating micromirror is defined as a micromirror that is unable to transition nominally from the –12° position to +12° or vice versa.
  13. Measured relative to the package datums “B” and “C”, shown in Mechanical, Packaging, and Orderable Information.
  14. The minimum or maximum DMD optical efficiency observed depends on numerous application-specific design variables, such as:
    • Illumination wavelength, bandwidth/line-width, degree of coherence
    • Illumination angle, plus angle tolerance
    • Illumination and projection aperture size, and location in the system optical path
    • IIlumination overfill of the DMD micromirror array
    • Aberrations present in the illumination source and/or path
    • Aberrations present in the projection path

    The specified nominal DMD optical efficiency is based on the following use conditions:
    • Visible illumination (400 nm – 700 nm)
    • Input illumination optical axis oriented at 24° relative to the window normal
    • Projection optical axis oriented at 0° relative to the window normal
    • f/3.0 illumination aperture
    • f/2.4 projection aperture

    Based on these use conditions, the nominal DMD optical efficiency results from the following four components:
    • Micromirror array fill factor: nominally 92%
    • Micromirror array diffraction efficiency: nominally 86%
    • Micromirror surface reflectivity: nominally 88%
    • Window transmission: nominally 97% (single pass, through two surface transitions)
  15. Does not account for the effect of micromirror switching duty cycle, which is application dependent. Micromirror switching duty cycle represents the percentage of time that the micromirror is actually reflecting light from the optical illumination path to the optical projection path. This duty cycle depends on the illumination aperture size, the projection aperture size, and the micromirror array update rate.
