Mini Laser Line Generator

Mini Laser Line Generator

…uniform intensity lines. It is designed for years of reliable operation in systems where size and weight are a limitation. These patented line-generating optics have been integrated into the Mini laser to yield the same uniform non-Gaussian lines as our well-known SNF laser line generators. Despite…

…produces a line of
illumination that appears distorted from perspectives
other than that of the projector. These distorted
perspectives can be used for an exact geometric
reconstruction of the surface shape.
In a typical 3D triangulation sensor, the laser line
provides…

Laser line patterns are often generated by cylindrical optics that produce a Gaussian line profile with a bright center
and fading ends. Lasiris patented optics spread the light into an evenly illuminated line.The result is a crisp, uniform
line with sharp ends.
Line Intensity…

…suited for Raman experiments in the visible region of the spectrum. Innova 70C Spectrum is a mixed gas lasers that can generate a number of laser lines from the UV to the near IR. Ultraviolet (UV) resonance Raman spectroscopy is a useful tool for the investigation of molecular structure, kinetics,…

…substantially reduces height resolution because the camera and laser line projector points
of view are so similar. Additionally, there is some occlusion.
Achieving optimum performance from a machine vision system based on laser line projection requires understanding the trade-offs inherent…

…wavelength. The internal pulse width modulation (PWM) of the DLP was used in this
experiment to dither the "white" lines of pixels.
[Note: PWM is used by the projector (from which the DLP has been extracted) to display
colors. The full color refresh cycle of the DLP is approximately…

…architecture is the single straight line
projection geometry. Here, simple optics fan out the laser beam so that it forms a straight line of
illumination on the part. When viewed by a camera from an angle different from the projector, the line is
distorted by the surface of the…

Key laser projector parameters for this application are line straightness,
uniform line thickness, and high pointing stability. Good line brightness
uniformity is also desirable but not mission-critical. Red (diode-based)
modules have been…
