FIGURE 1. A cross-sectional diagram of a fluidic channel illustrates the concept of spatially modulated emission (a). A spatially patterned mask modulates the fluorescent light directed to a large-area detector. The excitation light is blocked by a filter in the detection path. Correlation analysis (b) compares the measured time-modulated signal and expected particle signatures. The data evaluation results in an intensity histogram and a speed profile of the detected particles that allows extraction of particle count and analyte volume, respectively.

OPTOFLUIDICS: 'Spatially modulated emission' advances point-of-care diagnostics

A robust, compact, low-cost 'spatially modulated emission' technique delivers high signal-to-noise discrimination and brings practical optofluidic biodetection out of the centralized...
An image from the FAST cytometer results from a rough scan of a sample containing a cell line spiked in peripheral blood. The system detected 288 objects for analysis. The analysis located the four tumor cells known to be in the sample and generated three false positives.

Fiberoptic scanning cytometer is fast

Detection of tumor cells in peripheral blood using immunocytochemistry and optical scanning is a promising method for screening and monitoring cancer.

Dense arrays may lead to high-resolution printers

If lasers could be stacked close enough together in a laser printer such that each was responsible for placing a dot on the paper, it would eliminate the current need for laser...
Xerox PARC’s first research team was assembled and charged with a mission: to invent the future. Don Scifres (third from right) managed PARC’s laser and optoelectronics projects from 1972 to 1983 and is currently CEO of SDL (San Jose, CA).

Twenty-five years at Xerox PARC

In September 1970, in a secluded building nestled among the hills and horse ranches just west of Stanford University (Palo Alto, CA), a select group of scientists from around ...
