Abstract: An illumination light adjusting system according to the present disclosures includes a color vision characteristics storage configured to store color vision characteristics of a user, and a wavelength characteristics changing unit configured to change wavelength characteristics of illumination light based on the color vision characteristics stored in the color vision characteristics storage.

Abstract: An air circulator includes a blower unit that is provided with an airflow opening on its front side and in which a grill is provided in the airflow opening and a support unit that supports the blower unit, and the grill is provided with plural airflow guide blades in a spiral manner and their inner end portions closer to the center of the spiral of the plural airflow guide blades are protruded in an airflow direction from their outer end portions made continuous to the airflow opening.

Abstract: The invention relates to short-wave infrared (SWIR) detector arrays, and methods for forming such arrays, comprising a light conversion layer (10) having a germanium-tin alloy composition. The shortwave infrared (SWIR) detector array comprises an absorber wafer (II) and a readout wafer (I). The absorber wafer (II) comprises a SWIR conversion layer (10) which has a Gei-xSnxalloy composition. The SWIR conversion layer (10) may have an internal structure comprising an array of rods (12) extending between a patterned support layer (40) and a doped silicon layer (10c). The detector comprises also a readout wafer (I) including an array of charge collecting areas and a readout electric circuit. The readout wafer (I) and the absorber wafer (II) are bonded by a low temperature bonding technique. The invention also relates to methods of fabrication of the SWIR detector array and to SWIR detector array applications such as a multi/hyperspectral LIDAR imaging systems.
