Abstract: A phase correction concept is introduced to improve the performance of a spatially multiplexed optic. In a specific example, the optic is a diffractive lens. A phase offset is added to extend the depth of field of the diffractive lens and increase its focusing intensity. This can result in increased signal-to-noise ratio. These diffractive lenses may be used for imaging, focusing, and/or delivering light to an area of interest. They may be used to realize miniaturized medical imaging based on different imaging modalities such as optical coherence tomography, Raman spectroscopy, and fluorescence microscopy. They may also be used for different purposes and applications, for example laser ablation.

Abstract: A heat pump module for a laundry treatment device and the laundry treatment device are provided. The heat pump module includes a compressor, a condenser, an evaporator, a casing and a cooling air passage. The casing has an accommodating chamber provided with a partition plate to divide the accommodating chamber into a first mounting chamber and a second mounting chamber, the compressor is disposed within the first mounting chamber, and the evaporator and the condenser are disposed within the second mounting chamber. The compressor has an air exhaust port and an air suction port; the condenser has a first end in communication with the air exhaust port; and the evaporator has a first end in communication with a second end of the condenser, and a second end in communication with the air suction port. The cooling air passage has an air outlet end in communication with the first mounting chamber, and an air inlet end in communication with the outside.

Abstract: A washing-drying machine is provided. The washing-drying machine includes: a main body and a clothes drying device. The main body is provided with a washing drum therein and a guiding assembly thereon, in which the guiding assembly is communicated with the washing drum to form an airflow loop. The clothes drying device includes a horizontal compressor, a condenser and an evaporator, in which the horizontal compressor, the condenser and the evaporator are connected in series to form a clothes drying loop, and the evaporator is connected with the guiding assembly.

Abstract: The present disclosure provides a washing-drying machine. The washing-drying machine includes: a cabinet; an inner drum rotatably disposed in the cabinet and defining an accommodating cavity therein, in which the inner drum has an air outlet communicated with the accommodating cavity; a condenser disposed in the cabinet and defining a condensation channel together with the cabinet, in which the condensation channel is communicated with the air outlet; and a filter detachably disposed in the cabinet and located between the air outlet and the condensation channel, in which the filter has an inlet communicated with the air outlet and an outlet communicated with the condensation channel and is provided with multiple layers of detachable filtering pieces.

Abstract: A laundry treatment apparatus includes a cabinet, a washing system and a heat pump system. The washing system is disposed in the cabinet, includes a washing tub, and is formed with a drying gas inlet and a drying gas outlet communicated with the washing tub respectively. The heat pump system is provided integrally and connected to the cabinet, and defines an entry communicated with the drying gas outlet and an exit communicated with the drying gas inlet.
