Background and Objective
Spectrally encoded endoscopy (SEE) is an optical imaging technology that uses spatial wavelength multiplexing to conduct endoscopy in miniature, small diameter probes. Contrary to the previous side‐viewing SEE devices, forward‐viewing SEE probes are advantageous as they provide a look ahead that facilitates navigation and surveillance. The objective of this work was to develop...
Background and Objective
The tethered spectrally‐encoded confocal endomicroscopy (SECM) capsule is an imaging device that once swallowed by an unsedated patient can visualize cellular morphologic changes associated with gastrointestinal (GI) tract diseases in vivo. Recently, we demonstrated a tethered SECM capsule for counting esophageal eosinophils in patients with eosinophilic esophagitis (EoE)...
A new type of spectrometer design for confocal-spectral microscopy is proposed in this paper. Spectral imaging is the technique to collect spectrum information of the sample at each point. By combining with the confocal microscope, the sign al related with the position including z-axis and the wavelength can be measured. To select appropriate wavelength ban d detected by PMT channel, various methods...
