Forth Dimension Displays, a leading supplier of Spatial Light Modulators (SLM) into the in-line 3D metrology market, has delivered the much improved metrology-specific interface board R12 to the first customers.
These customers are updating their existing product to make best use of the smaller footprint of the R12 interface board, the capability to “daisy-chain” multiple boards and the new, size-matching high power LED drive board. Typically, a 3D metrology application requires to trigger several off-axis structured light projectors sequentially in a daisy-chain to enable shadow-free image analysis. The high power LED driver board matches to today’s brightest and most compact LEDs. Increasing the projector’s brightness reduces the camera exposure times for in-line 3D AOI and 3D SPI significantly, therefore allowing higher in-line inspection speed. The optional LED drive piggy-backs onto the R12 board as shown below, making it a very compact system to be integrated into the structured light projector.
The R12-LED board combination drives the 1 MPixel, WXGA SLM and the 1.3 MPixel, SXGA SLM, both renowned for its fast and precise digital performance. The metrology line-up is completed with the 3.1 MPixel, QXGA-3DM system for an even more detailed stripe projection. The QXGA-3DM can also be equipped with the LED drive board.
As always Forth Dimension Displays offers the complete range of product documentation with the development kit and support for projector design by our application engineering team.
