Abstract: A method for use in imaging an object through a scattering medium comprises illuminating the object sequentially point-by-point through the scattering medium with incident electromagnetic radiation propagating along an illumination direction so that the incident electromagnetic radiation interacts with the object to cause the object to generate and emit electromagnetic radiation, wherein the incident electromagnetic radiation is formed by spectrally dispersing initial electromagnetic radiation in a direction transverse to the illumination direction so as to form spectrally dispersed electromagnetic radiation and by spatially focusing the spectrally dispersed electromagnetic radiation through the scattering medium to the object.

Abstract: A method for use in light-sheet imaging of an object through a scattering medium comprises illuminating the object through the scattering medium with incident electromagnetic radiation propagating along an illumination axis so that the incident electromagnetic radiation interacts with the object to cause the object to generate and emit electromagnetic radiation. The incident electromagnetic radiation is formed by spectrally dispersing initial electromagnetic radiation in a direction transverse to the illumination axis so as to form spectrally dispersed electromagnetic radiation and by spatially focusing the spectrally dispersed electromagnetic radiation through the scattering medium to the object. The method comprises forming an image of at least a portion of the emitted electromagnetic radiation propagating along a detection axis, wherein the detection axis and the illumination axis are non-collinear, and sensing the formed image.

Abstract: A cutting device includes a housing formed with a handle portion and an accommodation portion, a cutting portion connected to the housing and at least partially disposed in the accommodation portion, a motor disposed in the accommodation portion and extending in a first linear direction, and a bottom plate extending in a plane of the bottom plate and formed with an opening through which at least part of the cutting portion passes. The cutting device further includes a worm gear and worm structure disposed in the accommodation portion. The cutting portion includes a chain and a guide plate connected to the housing and used for supporting the chain. The motor includes an output shaft, the cutting portion is connected to a driving shaft, the output shaft transmits power to the driving shaft through a worm gear and a worm, and the driving shaft is capable of driving the chain.

Abstract: An optical coherence tomography system for imaging a sample is configured so as to illuminate a region of interest of the sample with incident light from an optical source. The optical coherence tomography system is further configured so as to interfere, on an optical detector, reference light from the optical source with offset returning light emerging from the sample along an offset collection path which is spatially offset from the region of interest of the sample, thereby creating interference on the optical detector.
