Abstract: A method and system for registering an imaging system to a sample container include a sample container configured to support a biological tissue sample and an imaging system for generating optical images of the biological tissue sample. The sample container includes an imaging window having a top surface in contact with the biological tissue sample and a bottom surface. The imaging system includes a scanning area that receives a portion of the sample container and an imaging device disposed below the scanning area. The imaging device emits a focused sample light signal towards the imaging window and receives a reflected sample light signal from the imaging window. By scanning the focal point of the sample light signal and measuring the reflected sample light signal, the location of the top surface of the imaging window can be determined, thus registering the imaging device to the imaging window of the sample container.

Abstract: A sifting device having four sieve-like layers for separating an unsoiled litter material from an animal waste comprises at least two nested trays configured to stack together. Each nested tray comprises a first screen tray and a second screen tray stackable and rotatable to each other, and each of the first and second screen trays has a base with a plurality of openings thereon. Each individual opening is sized to permit the unsoiled litter material to pass through, and to prevent the animal waste from passing through. The openings on the screen trays are arranged in a concentric, circular and intermittent manner. By rotating the screen tray, the sifting device can allow the unsoiled litter material to pass through or form an imperforate base by blocking all the openings. This provides an advantage of operation simplicity with minimized risk of clogging.

Abstract: A real-time wavelength correction system for visible light is co-operated with an optical system to make a parallel light beam split into a zero-order diffractive parallel light beam and a first-order diffractive parallel light beam. The zero-order diffractive parallel light beam focuses on a first back focal plane to form a first light spot. A drift of the first light spot is applied to determine an angular drift of the parallel light beam. The first-order diffractive parallel light beam is focused on a second back focal plane to form a second light spot. A drift of the second light spot is applied to determine an angular drift of the first-order diffractive parallel light beam. The angular drifts of the parallel light beam and the first-order diffractive parallel light beam, which are changed with real time temperature variation, are applied to correct the wavelength of the parallel light beam.
