Double-purpose in vivo fluorescence photograph optical filter device for mobile phone and digital camera with replaceable lens

Abstract

The invention relates to the in vivo fluorescence imaging field, and especially relates to a double-purpose in vivo fluorescence photograph optical filter device for a mobile phone and a digital camera with a replaceable lens; the in vivo fluorescence photograph optical filter device comprises an ear clip type fixed clip, an adjustable aperture, an UV optical filter, and optical filter clasp, a circular polarization film and a switch ring; the ear clip type fixed clip comprises an inner thread interface used for threading the adjustable aperture or the switch ring; the side portion of the inner thread interface is connected with an elastic rod via a telescopic folding extension bar; the other end of the elastic rod is connected with an antiskid block; the camera side of the adjustable aperture, the circular polarization film and the optical filter clasp is respectively provided with an outer thread; the other sides of the adjustable aperture, the circular polarization film and the optical filter clasp are respectively provided with an inner thread; the UV optical filter is embedded in the optical filter clasp. The device can remove the UV excitation light influences on digital imaging in a fluorescence photograph process, thus enabling the digital picture to record and keep the fluorescence color and intensity authenticity.

Description

technical field [0001] The invention relates to the field of living body fluorescence imaging, in particular to a living body fluorescence photographing filter device dual-purpose for a mobile phone and a digital camera with an interchangeable lens. Background technique [0002] Taking photos and videos with a mobile phone or a digital camera is a convenient and quick way to record images. Taking pictures with a mobile phone or a digital camera, recording the images, and then analyzing the color of the digital images is an image recording method that is increasingly used in dermatology and other departments. With the technological advancement of mobile phones and interchangeable lens mirrorless digital camera lenses, the improvement of the quality of photographed pictures, and the convenience of picture storage and sharing, are becoming more and more popular among medical staff. In the process of photodynamic diagnosis and treatment, in order to conveniently record the fluo...

Problems solved by technology

However, when taking fluorescent photos, based on the imaging and color processing mechanism of mobile phones and digital cameras, if the correct filter is not used or the filter is used improperly, the color of the fluorescent photo will be seriously distorted

Ultraviolet excitation light of a specific wavelength is needed in the fluorescence photography process, and the excitation light can be reflected and enter the lens of the mobile phone and camera, but the imaging system of the mobile phone and digital camera cannot identify and remove this reflection, so when strong reflection After the ultraviolet excitation light is recorded by the camera at the same time, it will affect the color and picture quality of the fluorescence imaging, so that the real fluorescence image cannot be recorded
