In this video-article we present a method for isolating single or multiple Drosophila da neurons from third instar larvae using the infrared capture (IR) class of Laser Capture Microdissection (LCM). RNA obtained from the isolated neurons can be readily used for downstream applications including qRT-PCR or microarray analyses.

FAQs
A scanner directs laser beams across a target surface and evaluates the returned signal to determine distance. Repeating this measurement across many locations produces a set of spatial coordinates rather than a single dimension. Successive measurements can then be combined into a three-dimensional point cloud, allowing engineers to represent complex surfaces digitally for later inspection or reconstruction.
Laser Geometry Capture records geometry without requiring extensive contact measurement. This is valuable when an object or environment contains complex shapes that would be difficult to document efficiently through direct dimensional checks. The resulting digital representation can expose deviations from design intent while reducing reliance on repeated physical measurement during engineering analysis and quality-control activities.
A three-dimensional point cloud organizes successive laser measurements into a digital description of an object or environment. Engineers can use this representation as the basis for dimensional inspection, CAD reconstruction, and reverse engineering. Because the captured points preserve spatial relationships, the model can also support documentation and evaluation of manufactured or built structures.
A typical workflow begins by directing a scanner's laser beams across the physical surface. The system determines distances from the returned signals, records measurements at successive locations, and combines them into a three-dimensional point cloud. Engineers can then use that digital output for inspection, reconstruction, documentation, or comparison with the intended geometry.
Engineers may select Laser Geometry Capture when they need to document complex geometry efficiently without extensive physical contact. The technique supports dimensional inspection, reverse engineering, and CAD reconstruction, making it useful for manufactured objects as well as built structures. It can also provide a digital record for engineering analysis when direct measurement alone is less practical.
The captured geometry can support quality control by revealing deviations from design intent, while CAD reconstruction and reverse engineering use it to reproduce or analyze existing forms. Engineering teams can also apply the digital representation to robotic guidance and documentation of built or manufactured structures. These uses extend the technique from measurement into design, inspection, and operational workflows.
