Embodiment 1

[0039] as attached figure 1 Shown:

[0040] Such as figure 1As shown, a miniature head-mounted microscope includes a micro probe and an imaging structure, the micro probe includes a housing 15, an objective lens 7, a scanner 14 and a collimator, and the housing 15 is a sealed structure of a polymer material, The volume of the housing 15 (that is, the entire micro-optical probe) is less than 5mm*5mm*5mm, here the volume is equal to 4mm*4mm*5mm; the objective lens 7 and the collimator are respectively fixed on the housing 15, and the housing 15 is also fixedly connected with a laser Input fiber 8, the laser input fiber 8 is a polarization maintaining fiber or photonic crystal fiber, the design wavelength is any wavelength between 700nm and 1600nm, the material of the laser input fiber 8 is optical glass, quartz, plastic or high molecular polymer, the laser input The optical fiber 8 is used to transmit the ultrafast laser pulse generated by the external excitation light source ...

Embodiment 2

[0049] Such as Figure 5 As shown, the difference between this embodiment and Embodiment 1 is that the outside of the driver 1 is rotated through the shaft hole to be provided with an angle adjuster 11, the angle adjuster 11 is a rectangular frame, and the first torsion beam 9 and the second torsion beam 10 are both passed through the shaft. The hole is rotatably connected to the angle adjuster 11, and the outer peripheral wall of the angle adjuster 11 is fixedly clamped with a first rotating shaft 12 and a second rotating shaft 13, and the first rotating shaft 12 and the second rotating shaft 13 are symmetrical about the center of the driver 1 , and the first rotation axis 12 is perpendicular to the axis of the first torsion beam 9 . Both the first rotating shaft 12 and the second rotating shaft 13 are rotatably connected to the housing 15 through shaft holes, thereby realizing the rotatable connection between the scanner 14 and the housing 15 . During use, the driver 1 can ...

Embodiment 3

[0051] Such as Figure 6 As shown, the difference between the present embodiment and the first embodiment is that the driver 1 is a regular prism, and the mirror surfaces correspond to the sides of the driver 1 one by one. The driver 1 in this embodiment is in the shape of a regular hexagonal column, and the upper and lower ends of the driver 1 are coaxially fixed with torsion beams by bonding. The six side walls of the driver 1 are all fixed with mirrors by bonding. Wherein, the optical film adopts the filter film 4 and the polarization splitting film 5 .

[0052] This embodiment is applied to the case where the reflected light and the incident light of the miniature laser radar module waiting to detect the object 19 have the same wavelength, and the specific working process of the scanner 14 is as follows:

[0053] The scanner 14 is rotated by rotating the torsion beam, so as to achieve the purpose of adjusting the incident angle of the laser. Such as Figure 7 As shown,...

Abstract

The invention relates to the technical field of head-mounted microscopes, and in particular relates to a miniature head-mounted microscope which comprises a microscopic probe and an imaging structure.The microscopic probe comprises an objective lens, a scanner and a collimator; the objective lens and the collimator are mutually fixed, and the scanner can mechanically rotate relative to the objective lens; the scanner comprises a driver and a mirror surface which are fixed with each other; the mirror surface comprises an ultrathin sheet and a photoelectric detector which are fixed with each other; the photoelectric detector is communicated with the imaging structure through a circuit; the photoelectric detector is positioned between the ultrathin sheet and the driver; and one end of the ultrathin sheet, which is far away from the photoelectric detector, is plated with an optical film. By adopting the scheme, the structure of the microscopic probe can be further reduced, so that the overall mass and volume of the microscope are reduced.

Description

technical field [0001] The invention relates to the technical field of head-mounted microscopes, in particular to a miniature head-mounted microscope. Background technique [0002] The research method combining behavior and neurological function of living samples of animals under study (hereinafter referred to as living samples) has become a research hotspot in the field of neuroscience in recent years. The existing technology mainly uses a desktop two-photon microscope to observe and record the activities of various types of nerve cells and neural circuits in the cerebral cortex of living samples, but this method has the following disadvantages: During the observation and recording process, the head of the living sample It needs to be kept in a fixed state, that is, the living samples are always under physical constraints and emotional pressure (fear, unknown) during the experiment, so the existing research methods cannot effectively study the living samples in the free-mov...
