fNIR Systems extract measurements from an LED light source at wavelengths of 730 nm and 850 nm, and also provide a unique feature that can be useful for identifying certain types of noise within recordings. This feature enables the fNIR imager to record measurements under “dark current” conditions.
Dark current measurements are always recorded in fNIR data output files (.nir and .oxy) and can be monitored during sensor placement, baseline, and overall testing measurement periods by selecting **** under **** buttons in COBI studio.
Time periods during which dark current measurements do not remain flat in close correlation with measurements taken at 730 nm and 850 nm can help identify noisy data segments. These regions can subsequently be marked and discarded from further hemoglobin content extraction analysis.
Noise is not always as obvious the sample shown, and dark current measurements offer a justifiable secondary measure for verifying the presence of noise in all cases.
BIOPAC is introducing Biopac Student Lab Home (BSL HOME)—a new product specifically geared towards teaching physiology labs remotely so students can still get hands-on, practical lab experience if social distancing and stay-at-home orders keep them out of the lab..
BSL HOME will allow your students to conduct physiology labs in the safety of their own home, dorm room, or any remote location.

Comparing Muscle Movement and Involvement between Boxing Punches In the fast-paced, high-intensity combat sport of boxing, the right punch can win a fight. However, boxing is also a sport where opponents can become exhausted in mere minutes of action, and prioritizing their strength is key to winning a fight. This team recorded EMG on test […]
