be further decreased by improving the wavelength resolution of the smartphone spectrometer, which can be achieved by reducing the slit size, utilizing a G-Fresnel with finer grating period, and optimizing the optical alignment. Theoretical analysis previously indicates that 1 nm resolution can be ac...
Comprehensive functional and structural examinations were performed to stratify children’s visual conditions for developing and validating the DL-based AIS. For unified examination, a teller vision card (Stereo Optical Company) was utilized to measure children’s monocular visual acuity44. In addition, ...
Smartphones are ideal to use as detector systems because of their powerful internal computers, optical sensors, global positioning systems (GPS), and most importantly, their ability to connect to the internet, through Bluetooth and WiFi [13,14,15]. Connectivity is a key benefit of smartphones ...
The smartphone integrated high-resolution complementary metal-oxide semiconductor (CMOS) sensors have been widely exploited to detect optical signals, relying on colorimetric, fluorescent (FL), and bio-chemiluminescent detections. In the last 5 years, there has been an exponential increase in the public...
Only one study [32], which employs accelerometers and optical sensors in a constrained home environment, resulted in higher precision than our system (50 %). However, the sensitivity of that system (22.2 %) was much lower than our system (73.0 %). Therefore, when considering both ...
Further research is needed to identify equichromatic surfaces for various optical probes. This may lead to the discovery of standard colorimetric indicators amenable for illumination-invariant colorimetric smartphone-based analysis. This progress could enable housing-free illumination-invariant colorimetric (bio...
analysis. The integration of image processing and ANN-based risk-stratification model improved the detection sensitivity of malignant lesions and high-grade OPML. Zeinhom et al. demonstrate a compact and lightweight optical device attached to the existing camera module of a smartphone for detection ...
The smartphone 102 can use the network interface 206 for communicating data over wired, wireless, or optical networks. By way of example and not limitation, the network interface 206 may communicate data over a local-area-network (LAN), a wireless local-area-network (WLAN), a personal-area-...
