  • Publication number: 20200116417
    Abstract: A thawing method for a thawing device includes: generating, by a radio frequency generation module, a radio frequency signal in a frequency range of 40 to 42 MHz; obtaining the radio frequency signal; and generating, by an upper electrode plate and a lower electrode plate, radio frequency waves of corresponding frequency in a thawing chamber according to the radio frequency signal, and thawing an object to be processed in the thawing chamber. Radio frequency waves using the above frequency range have shorter thawing time, higher temperature-uniformity and lower juice loss rate than radio frequency waves of other frequencies.

  • Patent number: 9921102
    Abstract: A moving platform borne infrared image-spectrum associated detection system includes an optical hood, a broadband optical system, a two-dimensional servo system, an infrared optical fiber, a Fourier interference spectrum module, an image-spectrum associated detection processing module, a power supply module, and a display module. Incident light enters from the optical hood to the broadband optical system, and is split by a spectroscope. Transmitted light is focused by a long-wave imaging lens group on an infrared detector for imaging. Reflected light is focused by a broadband spectrum lens group to an optical fiber coupler, enters the Fourier interference spectrum module through the infrared optical fiber to form an interference pattern, and undergoes Fourier transform to obtain spectral data.

  • Patent number: 9651763
    Abstract: The present invention discloses a co-aperture broadband infrared optical system, belonging to the field of infrared optical system. The system realizes long wave infrared (LWIR) imaging and broadband infrared spectrum measurement, and solves the problems of limited optical path layout, large volume and high cost of an optical system. The present invention includes a Cassegrain lens, a spectroscope, a reflector, several lens groups, an FPA interface and an optical fiber interface. Light (2 ?m˜12 ?m) is incident to the Cassegrain lens to be focused, then is split by the spectroscope, where 50% of the LWIR light (8 ?m˜10 ?m) passes through the lens group for aberration correction, and the image plane is focused again at the imaging interface. The other 50% of the LWIR light (8 ?m˜10 ?m) and the infrared reflected light (2 ?m˜8 ?m and 10 ?m˜12 ?m) pass through the lens group, and are reflected by the reflector, then focused at the optical fiber interface.
