Photonics West 2012: DLP technology finds more application in bio
DLP technology has already been applied to designs for contactless, 3-D fingerprint scanners, for example, according to Mike Troy, CEO at FlashScan3D (Richardson, TX), a 3-D biometric device maker. But packaged in the DLP LightCrafter module, the technology could yield faster fingerprint scans, internal data storage, and--because of its size--even a portable device, he says.
Bio applications enabled for the DLP LightCrafter include chemical analysis, spectroscopy, metrology, photostimulation, and even optical coherence tomography (OCT). For OCT, the module's spatial light modulation ability comes into play to bring higher speeds. And on demo at the booth was Christie Medical Holding's (Memphis, TN) VeinViewer Vision enhanced with the module, enabling a real-time digital projection of a patient's veins (see image)--a useful technology when veins are difficult to detect.
