Cutting Edge Profile Measurement of a Micro Drill Bit Utilizing Chromatic Confocal Probes and Blind Reconstruction Strategy

Nanomanufacturing and Metrology
Abstract Measurement of the cutting edge of a micro drill bit presents considerable challenges due to its steep surface gradients and shape. Aiming to overcome these difficulties, a measurement system that combines a compact chromatic confocal probe, a machine vision system for pre-alignment, and a four-axis scanning stage was developed.

Towards many colors in FISH on 3D-preserved interphase nuclei [PDF]

, 2006
The article reviews the existing methods of multicolor FISH on nuclear targets, first of all, interphase chromosomes. FISH proper and image acquisition are considered as two related components of a single process.
