摘要： Provided are an image forming apparatus and an image forming method which are capable of obtaining an image of a measured object using a relatively simple structure in a short time. In the image forming apparatus, an electromagnetic wave generated by an electromagnetic wave generator is emitted to the measured object through a spatial modulation unit for spatially modulating a signal intensity. An electromagnetic wave that has passed through the measured object is measured by an electromagnetic wave detecting unit. A measurement signal is processed by a signal processing section based on a reference signal synchronized with the signal intensity modulated by the spatial modulation unit. The image is formed by an image acquisition section.
