Abstract
In an image forming apparatus (1), an excitation light source (10) irradiates an object with excitation light for a first fluorescence substance and excitation light for a second fluorescence substance, a notch filter (20) transmits fluorescence in a wavelength range specific to each fluorescence substance among return light from the object, an imaging unit (30) separately captures images of the fluorescence in respective wavelength ranges, and an image processing unit (40) superimposes these images.
Claims9
An image forming apparatus comprising:
- an excitation light source configured to irradiate an object with excitation light for a first fluorescence substance and excitation light for a second fluorescence substance;
- an optical filter unit configured to transmit, from light from the object, fluorescence in a first wavelength range including near infrared or short wave infrared of the first fluorescence substance and fluorescence in a second wavelength range including short wave infrared of the second fluorescence substance;
- an imaging unit configured to capture an image of fluorescence in the first wavelength range and an image of fluorescence in the second wavelength range that have transmitted through the optical filter unit;
- and
- an image processing unit configured to superimpose the image of the fluorescence in the first wavelength range and the image of the fluorescence in the second wavelength range in the imaging unit.
