A microwave heating apparatus () includes a burning chamber () in which an object () to be burned is placed, a magnetron () for applying microwaves into the heating apparatus, a cooling gas introducing mechanism () for introducing a cooling gas from outside the heating apparatus into the heating apparatus, a cooling gas channel () through which the cooling gas flows to the burning chamber (), heat-generating members (to) for self-heating with microwaves applied thereto to heat the cooling gas flowing through the cooling gas channel () and a control section () for, when the burning chamber () having the object () to be burned placed therein is cooled, causing the cooling gas introducing mechanism () to introduce the cooling gas into the heating apparatus, and causing the magnetron () to intermittently apply microwaves into the heating apparatus.

Microwave heating method and microwave heating apparatus

In an optical interference measuring method according to the present invention, light emitted from a light source unit is split into measuring light and reference light, coherent light is detected that is obtained by interference of the reference light and the measuring light reflected from or scattered rearward from a measuring object, an optical-path length adjustment mechanism provided in the optical path of the reference light is driven to change the optical path length of the reference light, it is decided whether an image based on the detected coherent light is a normal image or a folded image based on the coherent light having varied with the change of the optical path length of the reference light, and the measuring object is measured from the detected coherent light based on a result of the decision about whether the image is a normal image or a folded image.
