Creating High Bit Depth Grayscale Images

Creating High Bit Depth Grayscale Images

Generating Grayscale Images Generating accurate images with a variety of bit depths is an important requirement for a number of industrial and medical uses for structured light. This note looks at some of the techniques and tradeoffs involved in generating such images on a DMD as well as some of the applications. The ‘black and white’ images captured by early still and motion cameras effectively used a continuous scale to capture light variations by the use of chemistry to lock in the image. Projecting the images used the same approach. Moving to digital technologies meant that the gray levels in…

Embedded USB 3 Streaming to Ajile DMD from Jetson TX2

Embedded USB 3 Streaming to Ajile DMD from Jetson TX2

Many Digital Micromirror Device users look to Ajile’s DMD controllers for their superior speed and flexibility. Now it’s possible to have precise, high-speed DMD control from a completely embedded system. The full Ajile Software Suite has been released for the NVIDIA Jetson TX2 and the performance so far has been excellent. Most DMD controllers and projectors depend on video interfaces like HDMI to receive image data to display. Not only do these video interfaces offer limited speed and control, but they also typically need a full PC with a video card. With the Ajile software SDK and GUI running directly…

Improved Imaging With Sub-Pixel Resolution

Improved Imaging With Sub-Pixel Resolution

Sub-Pixel Resolution For Improved Image Quality As 3D imaging continues to become increasingly important in both research and industry, tools are becoming available to turn theoretical research into practical technology. Our systems are well positioned to do this, and we are now in the process of enabling sub-pixel resolution to achieve even higher levels of 3D image quality. A key limitation of optical instruments is the size of the sensor’s pixels. When features being imaged are smaller than the pixel size, typical responses are to use a more expensive sensor with more pixels per unit area or to modify the…

Ajile 10x Boost to Data Transfer Speeds With USB3.0

Ajile 10x Boost to Data Transfer Speeds With USB3.0

High Speed Data Transfer with AJD-4500-U and AJP-4500-U Ajile’s key strength lies in our products’ ability to create, control, and capture light at high speeds without sacrificing accuracy. We are pleased to announce an important step forward with the release of the AJD-4500-U and AJP-4500-U versions of our DMD controller and structured light projector this month. The -U versions feature USB3.0 data transfer at speeds exceeding 2000 binary frames/second. This upgrade lets users take full advantage of the high frame rates featured by Ajile’s DMD-based systems. Emerging developments in the realm of image processing depend on a constant flow of…
