Humidity Sensing

The article presents an inexpensive and simple method of fiber optic interference relative humidity (RH) sensors based on silk fibroin (SF) films. The sensors were made on standard multimode telecommunications optical fibers using dip-coating method and examined using broadband light sources. The measuring stand at which the basic sensor parameters were measured and the measured parameters were presented. Full Text: PDF ReferencesY.-G.

Beef Color

The effects of incandescent (INC), cool-white fluorescent (FL), and metal halide (MH) light sources on the appearance of medium, lean, and extra lean ground beef meat were investigated. Meat color with INC illumination was preferred (P < 0.05) over that with MH illumination for all meat types, and over FL illumination for extra-lean and medium meats. The majority of the panelists described the meat as red under INC lighting, but brown or dark red under FL and MH lighting. Relative luminance data, collected with a fiber optic probe connected to a photo diode array, demonstrated the reason to be a lack of redness in the FL and MH light sources.
