Abstract:
The present invention provides a levitation apparatus and a levitation method. The levitation apparatus comprises: an upper electrode and a lower electrode, which are arranged while being separated each other; a main power source for levitating an object, which is charged by applying a voltage to the upper electrode and the lower electrode, against gravity with an electrostatic force, which is generated by the voltage; a laser for heating the charged object; and a spherical mirror for re-reflecting a reflection light, which is reflected from the charged object, to the charged object. The reflection light is generated since the charged object reflects an output light of the laser passing through a through-hole, which is formed in the center area of a surface of the spherical mirror.

PURPOSE: A method for simultaneously measuring the infrared properties of samples is provided to enable the measurement of infrared properties of translucent or transparent samples using a contact heating method. CONSTITUTION: A method for simultaneously measuring the infrared properties of samples comprises the following steps. The sensitivity of a device is calculated by measuring the radiance of a black body(S31). The first emissivity of a first substrate and the second emissivity of a second substrate are calculated(S32). The first substrate having the first emissivity is positioned between a heater and a sample to calculate the first radiance of the sample(S33). The second substrate having the second emissivity is positioned between the heater and the object sample to calculate the second radiance of the sample at the prescribed temperature(S34).

Abstract:
A high precision blackbody for calibration of tympanic thermometers is provided to improve stability of temperature and massively produce isothermal blocks conveniently by processing a screw thread. A high precision blackbody(100) for calibration of tympanic thermometers includes a thermal insulator separation plate(140), a blackbody cavity unit(110), and a temperature controller(130). The separation plate partitions the inside of the high precision blackbody vertically. The blackbody cavity unit is placed on the upper part of the separation plate and has a black cavity(114) and a cylindrical isothermal block(112) made of oxygen-free copper and wound by a hot wire(104) to heat the blackbody cavity. The temperature controller is placed on the lower part of the separation plate and controls the temperature of the blackbody cavity unit.
