Disclosed is a 4-method for preparing original data of an odor image includes a measurement result acquiring step of acquiring each measurement result measured with respect to the odor substance included in the sample in each of a plurality of sensor elements of an odor sensor, and a data processing step of generating the original data for representing the odor of the sample in the image by processing each of the acquired measurement results. Each of the sensor elements has different detection properties with respect to the odor substance. In a case where each of the original data items is represented in a small image, the odor of the sample is represented in an odor image in a predetermined display mode in which small images are assembled, and each of the small images is varied in accordance with the magnitude of the value of each original data item.

Method for preparing original data of odor image

The odor exploration method explores an odor based on odor information generated using a plurality of sensor elements each outputting a detection signal according to the state of adsorption by indicating an adsorption reaction unique to each odor substance, and an arithmetic unit generating the odor information by quantifying each detection signal from the sensor elements. The method includes a detection step detecting a first gas containing odor substances, a generation step generating a first odor information group generated based on a detection result of the first gas, a preparation step preparing a second odor information group generated based on a detection of a second gas, and a calculation step calculating a sum of or a difference between the second odor information group and the first odor information group based on a sum of or difference between the odor information generated for the first gas and for the second gas using the same sensor element.

Odor exploration method and odor exploration system

A data structure includes a main data storage area in which main data is stored, and an odor data storage area in which odor data is stored. The odor data is based on a measurement result of an odor in air measured by an odor sensor. The odor data storage area stores a plurality of pieces of the odor data. The main data storage area includes a main data ID area for storing a main data ID indicating that the stored data is the main data. The odor data storage area includes an odor data ID area for storing an odor data ID indicating that the stored data is the odor data.

Provided is a Fourier transform-type spectroscopic device capable of improving an acquisition speed of a molecular vibration spectrum. The Fourier transform-type spectroscopic device () of the present invention rotates a scanning mirror () by rotation of a rotating shaft () to change a light path length of scanning light and delay or advance the scanning light with respect to reference light in accordance with a rotation angle of the scanning mirror () from an initial position, and is thus capable of moving the scanning mirror () at a high speed as compared with a case where a movable mirror is mechanically moved as in a conventional Fourier transform-type spectroscopic device, thereby improving an acquisition speed of a molecular vibration spectrum.
