Technical Field

Background

The incident spectrum signal reaches the grating after passing through the slit, and various spectral lines are separated after diffraction by the grating, and as different wavelength spectral lines of different elements are densely focused on different positions of the Roland circle, in order to detect all spectrum signals, all spectrum signal detectors are required to be arranged on the Roland circle, and the basic function of the spectrum signal detectors is to convert the received optical signals into electrical signals. The spectrum signal detector receives the spectrum signal, but since the effective detecting unit edge of the current common spectrum signal detector has a certain distance from the edge of the detector shell, an ineffective detecting space is formed, which results in that the spectrum signal detector is completely arranged on the Roland circle, but the ineffective detecting space of two sections exists between the former spectrum signal detector and the latter spectrum signal detector, so that full spectrum detection cannot be realized, and therefore, a full spectrum signal acquisition device is needed to solve the problem.

Detailed Description

The technical solution of the present invention will be further described below with reference to the accompanying drawings of the embodiments of the present invention, and the present invention is not limited to the following specific embodiments. It should be noted that, without conflict, the embodiments of the present invention and features of the embodiments may be combined with each other.

As shown in fig. 1 to 2, a full spectrum signal acquisition device includes: a rowland circle body, a plurality of first lenses 200, a plurality of second lenses 300, a plurality of first detectors 400, and a plurality of second detectors 500; the first lenses 200, the second lenses 300, the first detectors 400 and the second detectors 500 are all arranged on the rowland circle body; each of the first lenses 200 faces one of the first detectors 400, each of the second lenses 300 faces one of the second detectors 500, and a plurality of the first lenses 200 are disposed to intersect a plurality of the second lenses 300. Further, the rowland circle body has a rowland circle plane 100, a slit 600 and a grating 700 are disposed on the rowland circle plane, an external light source passes through the slit 600 and irradiates the grating 700, and a plurality of first lenses 200 and a plurality of second lenses 300 are disposed on the rowland circle plane.

In one embodiment, by disposing the first detectors 400 and the second detectors 500 on the rowland circle body, the positions where the first detectors 400 and the second detectors 500 are disposed are positions irradiated by an external light source. That is, by providing a plurality of first detectors 400 and a plurality of second detectors 500, the range which can be irradiated by the external light source is fully arranged, so that the light source can be well received. That is, the specific number of the first detector 400 and the second detector 500 may be adjusted according to the irradiation range of the external light source, it is worth mentioning that, in order to ensure that the first lens 200 is matched with the first detector 400, the second lens 300 is matched with the second detector 500, and thus, the number of the first lens 200 is consistent with the number of the first detector 400, and the number of the second lens 300 is consistent with the number of the second detector 500, that is, the numbers of the first detector 400, the second detector 500, the first lens 200 and the second lens 300 may be specifically adjusted according to the irradiation range of the external light source, which is not cumbersome in this embodiment.

In one embodiment, each of the first lenses 200 is disposed at an angle of 45 ° to the rowland circle plane 100. Each of the second lenses 300 has an angle of-45 ° with respect to the rowland circle plane 100. Further, the first lenses 200 and the second lenses 300 are reflective lenses. It should be noted that the shapes of the first lenses 200 and the second lenses 300 are parallelograms. The hypotenuse of each first lens 200 abuts against the hypotenuse of one second lens 300. It is further noted that each of the first detectors 400 is disposed above one of the first lenses 200. Each of the second detectors 500 is disposed under one of the second lenses 300. That is, when an external light source, that is, an incident light is irradiated onto the grating 700 through the slit 600, a diffraction spectrum is formed by diffraction of the grating 700, an emitted spectrum signal is upwardly reflected to the first detector 400 through the first lens 200, when an external light source, that is, an incident light is irradiated onto the grating 700 through the slit 600, a diffraction spectrum is formed by diffraction of the grating 700, an emitted spectrum signal is downwardly reflected to the second detector 500 through the second lens 300, a plurality of first lenses 200 and a plurality of second lenses 300 are closely spaced apart from each other, and since the first lens 200 and the second lens 300 are in a parallelogram shape, a gap between them is a slant line when the first lens 200 and the second lens 300 are close together, and since the first lens 200 is 45 ° to the rowland plane 100, the second lens 300 is-45 ° to the rowland plane 100, even if the spectrum signal is irradiated onto the second lens 300, the spectrum signal is well reflected to the second detector 500 by the second lens 300, and the first lens 200 is well reflected to the second lens 300, and the second half of the spectrum signal is well detected by the first lens 300, and the second half of the spectrum signal is well reflected to the second lens 300. Therefore, by adopting the full spectrum signal acquisition device, the acquisition and detection of signals can be well ensured, and the full spectrum line detection without missing of spectrum signals can be realized.

In one embodiment, the plurality of first detectors 400 and the plurality of second detectors 500 are each spectral signal detectors. That is, the first detector 400 and the second detector 500 may be detectors capable of detecting an optical signal, for example, the first detector 400 and the second detector 500 may be CCD detectors. That is, the first detector 400 and the second detector 500 may be other spectrum signal detectors, which is not described in detail in this embodiment.

In summary, the above-described embodiments are not intended to be limiting embodiments of the present invention, and modifications and equivalent variations, which are within the spirit and scope of the present invention, will be within the technical scope of the present invention.
