Diagnosis of Skin Tumors During Mohs Micrographic Surgery
Automated imaging and objective diagnosis of excised tissue specimens during cancer surgery is a promising approach for increasing the efficiency of the most advanced surgical procedure. Firstly, this quantitative approach can increase the efficacy of surgery by eliminating the errors related to the subjective inter-observer evaluation of...

Vision Library or Vision-Specific IDE: Which is right for you?
Commercial machine vision software is currently classified along two lines: the conventional vision library and the vision-specific integrated development environment (IDE). Determining which software is right for your vision project depends upon a variety of factors: ease-of-use, productivity, flexibility, performance, completeness, and...

Dynamic – Dynamic Range
The dynamic or dynamic range of a CCD-camera system is a widely used term to characterize the ability of a camera system to measure or image light/dark differences. In the field of photography, the dynamic range is analogous to the contrast range. However, each manufacturer defines dynamic range differently. A distinction must be made, between the...

High Performance SWIR Imaging Cameras
Silicon based area detectors (e.g. CCDs or CMOS) are widely used in high performance imaging applications, detecting wavelengths from soft x-ray through to near infrared (NIR). Typically the quantum efficiency (QE) of these detectors decreases rapidly as the detection wavelength increases further into the NIR region.

Modifying Laser Beams: No Way Around It, So Here’s How
To apply a laser to an industrial process, medical therapy, or communications technology, it is usually necessary to modify the laser beam to achieve the desired results. Beam measurement tools make this possible. We will discuss how to match an appropriate laser beam profiling technique to a laser application, including building an aligned...

Fabricating and Testing Freeform Optics: Current Capabilities, Lessons Learned and Future Opportunities
Freeform optical shapes or optical surfaces that are designed with non-symmetric features are gaining popularity with lens designers and optical system integrators. A common question about freeform optics is, “If I design it, can you really make it?” This paper will overview a freeform optical fabrication process that includes generation, high...

Methods for Measuring Flat Panel Display Defects and Mura as Correlated to Human Visual Perception
Human vision and perception are the ultimate determinants of display quality, however human judgment is variable, making it difficult to define and apply quantitatively in research or production environments. However, traditional methods for automated defect detection do not relate directly to human perception. Accurately correlating human...

Narrow-Line Fiber-Coupled Modules for DPAL Pumping
A new series of fiber coupled diode laser modules optimized for DPAL pumping is presented, featuring greater than 400W from a 600µm core fiber of 0.22NA. Addressing one of the key challenges in DPAL pumping, the modules achieve a spectral width of <<0.1 nm and wavelength tunability of +/- 0.15 nm. A limiting factor in the reduction of the spectral...

UVSCALE Visualizes UV light amount distribution by color density
One side of the base film has a UV light sensitive layer, with the opposite side having a white-colored layer. The light sensitive layer changes color according to the amount of UV light it receives, so the amount of light distributed on the exposed surface is easily seen by observing a light sensitive layer and white-colored layer are attached to...

Vision Research High-Speed Digital Cameras Instrumental in Teaching Construction Site Safety
There is a good reason construction workers are asked to wear hard hats, gloves, safety goggles, and various other safetyequipment while on the job; construction sites are dangerous. Filled with heavy and sharp objects, platforms of varying heights, flying sparks and debris, and a number of other potentially dangerous elements, it’s no wonder so...
