In general imaging technology, since the image is acquired by separating the light received by the camera into single or several to several tens of wavelength information in the wavelength range of visible light or infrared light by the spectroscopic sensor, the physical properties and characteristics of the sample can be accurately There is a limit to doing.

Recently, ultra-spectroscopic imaging technology has been developed that can distinguish the physical properties and traits of a sample by acquiring images by separating the received light into hundreds to hundreds of wavelengths information by using an ultrasound spectrometer and an ultrasound image sensor Was developed.

These ultra-spectroscopic imaging technologies were first used for military purposes in airplanes or satellites and used for identification of targets. For civilian use, there are remote exploration fields such as cultivation conditions of crops, distribution of minerals, Is being used in the field.

The ultrasound imaging technique divides the light received by the ultrasound spectrometer into wavelengths by the ultra-spectroscopic device, allocates them in the row direction of the array of detectors, spatially divides them in the column direction, Information at the same time.
