Embodiment approach 9

[0028] Embodiments 2, 3 and 4 are all impossible or difficult to achieve with the V-groove fixation method. Embodiment 4 cannot be achieved by stacking method. Therefore, the present invention has many advantages for making the output end of the IFU optical fiber. When installing optical fibers with the V-groove fixing method, the cover plate may move. When the number of installed optical fibers is large, it is difficult to control the front optical fibers from moving. However, the microhole fixing method of the present invention only needs to install the optical fibers in sequence, and the optical fibers are not easy to move after entering the hole, so it will not increase the difficulty of installation when the number is large, and a long fiber optic array. In addition, the processing of microporous substrates is more flexible than that of V-groove substrates. The V-groove fixation is fixed by squeezing the contact fiber, which will cause stress to the fiber. However, in...

Abstract

The invention relates to the field of optical fiber spectral imaging research, and provides an optical fiber slit end arranging and fixing device for an integral view field unit. The device is used for fixing emergent optical fibers at a slit end of an integral view field unit, the optical fibers are arranged and emitted according to a certain rule, and a certain distance is kept between the adjacent optical fibers, so that the incident requirement of a spectrograph is met. The optical fibers are fixed through deep holes, round holes are punched in the substrate, and one optical fiber is fixed in each hole. In order to conveniently insert the optical fiber into the hole, the front end of the hole is designed to be conical. Compared with a common V-groove fixing method, the fixing method in a direct insertion hole mode has a more free arrangement mode and a more flexible and diversified processing method.

Description

technical field [0001] The invention relates to the field of optical fiber spectral imaging research, in particular to an optical fiber slit end arrangement and fixing device for an integral field of view unit. Background technique [0002] An integrating field unit (IFU) is a spectral imaging device. It can cut the two-dimensional image of the target into small units, transmit the optical information to the slit end through the optical fiber array, and then couple it into the spectrometer for spectral analysis to obtain its spectral image information. Therefore, it can obtain two-dimensional spatial position information (x, y) and one-dimensional spectral information (λ) of spatial samples through a single exposure. The IFU is mainly composed of an array end, a slot end and an optical cable connected in the middle. Different spectrometers have different requirements for the arrangement of optical fibers, and require a fixed distance between optical fibers to facilitate co...
