SEPTEMBER 2020 I DESIGN007 MAGAZINE 33 of 3D imaging in vast, well-lit areas including outdoor locations. The Pattern Blazer features four standard LED spectral options, blue (480 nm), red (660 nm) near-infrared (860 nm), and broadband white (4800K). It uses standard C-mount machine vision lenses designed for 1″ image sen- sors. The Pattern Blazer incorporates pinhole-free precision reticles pat- terned by photolithogra- phy to produce thinner lines, sharper edges, and more homogeneous illumi- nation than lasers and without diffraction or speckle effects. Pro- jected patterns for the Pattern Blazer include lines, grids, edges, and random dot point clouds. Other wavelength LEDs and cus- tom patterns can be provided upon request.

Innovations in Optics, Inc. introduces the Pattern Blazer, a high-power, LED fixed-pattern projector for structured lighting and stereovision in 3D machine vision. Pattern Blazer applications include determination of object shape and orientation, contour mapping of parts, surface defect detection, depth measurements, guide- lines, edge detection, and alignment. A near infrared ver- sion is suited for video identification in long-range CCTV security and surveillance. The Pattern Blazer projects patterns with an intensity that is at least 5X to 10X greater at the same distance than other "high power" LED Pattern projectors for similar pattern size and wavelength. It can be operated in either continuous, PWM or pulsed current modes. Extremely bright pat- terns at long working distances enables the use Pattern Blazer World's Brightest LED Pattern Projector in 3D Vision Applications
