Abstract:
Provided are an imaging method and device for imaging using far infrared light that make it possible to quickly image a subject without producing damage or a non-linear phenomenon in the subject. A variable-frequency coherent light source is used, illumination light from the light source is irradiated onto a linear area on an imaging subject, transmitted or reflected light is used to form an image of the imaging subject, a non-linear optical crystal is used for wavelength conversion, and a one-dimensional or two-dimensional array sensor is used to image the imaging subject while the imaging subject is moved in at least one direction.

Claim (Index 1):
A far-infrared imaging apparatus, comprising:\n a wavelength-tunable far-infrared light source in which first pump light and first near-infrared light are incident onto a non-linear optical crystal to generate first far-infrared light; an illumination optical system that irradiates the first far-infrared light on a sample; a far-infrared light imaging optical system that forms an image of the sample; a detecting non-linear optical crystal onto which second far-infrared light transmitting through or reflected from the sample and second pump light are incident, thereby generating second near-infrared light; a sensor that detects the image; and a detecting optical system that introduces light emitted from the detecting non-linear optical crystal onto the sensor, wherein the second far-infrared light is incident obliquely onto an upper surface of the detecting non-linear optical crystal, wherein the second pump light is incident onto a side surface of the detecting non-linear optical crystal, and wherein the side surface of the detecting non-linear optical crystal onto which the second pump light is incident is approximately parallel to an optical axis of the second far-infrared light.
