The challenge There are many different varieties of pollen within various species. Several varieties of pollen were analyzed using Dynamic Image Analysis to test if their morphology (shape characteristics) could be used as a differentiator among the various types, and to differentiate between whole pollen grains and pieces or debris. Size-only methods often cannot make [...]

The challenge Finely-cut diamond abrasive is used to make industrial drills, grinding wheels and discs, dental tools and lapidary equipment. Grinding tools are used to shape steels, alloys, ceramics, glass, granite and other materials. Two sizes, or grits, of abrasive were studied. Below is a typical raw image of particles from each of the two [...]

The challenge Abrasive Powders are used in a variety of everyday applications. It can be the particles used to polish teeth, abrasive polishes to make expensive automotive finishings shine, or even the sandpaper a carpenter uses for his daily work. All of these powders are designed to remove material. Some are more aggressive in removal [...]

The challenge Early detection of wear particles in lubricating and hydraulic fluids is critical to having a proper predictive maintenance program. It is this early detection and identification of wear particles that permits the extension of engine life and can minimize down-time of equipment. The challenge is to count the number of contaminant particles between [...]

Some of the examples in the Software section used artificially-prepared mixes of spheres and another kind of particle, for the sake of obviousness. Here we will look at a real-world sample that consists of two classes of particles. In the typical raw image shown below, there are small round particles together with larger, more irregular [...]
