From: Portable bacterial identification system based on elastic light scatter patterns
Schematic diagram of the portable bacterial identification system using elastic light scatter patterns. (a) The distance parameter D1(1.2 inch, from plate to the scatter camera) and D2 (4.5 inch, from imaging camera to the plate). (b) The system consists of a linear stage, a rotational stage, and two cameras (imaging and scattering), a laser diode of 635 nm, and electroluminescent light for back-illumination. Approximate size W × L × H = 6 in × 12 in × 10.5 in. The device weights about 9 lb.
