specific Embodiment approach 1

[0027] The device for reconstructing the optical parameter field of a diffuse medium based on a microlens array and a pulsed laser in this embodiment combines figure 1 Its composition includes: laser controller 1, laser head 2, dispersive medium 3, first microlens array light field camera 4, second microlens array light field camera 5, third microlens array light field camera 6 and data acquisition and processing System 7, the data acquisition and processing system 7 is connected to the laser controller 1, and the laser controller 1 is connected to the laser head 2; the data acquisition and processing system 7 is also simultaneously connected with the first microlens array light field camera 4 and the second microlens array light field camera 5 , the third microlens array light field camera 6 is connected;

[0028] Wherein, the center point of laser head 2, the first microlens array light field camera 4, the second microlens array light field camera 5, and the third microlens ...

specific Embodiment approach 2

[0029] The difference from Embodiment 1 is that in the device for reconstructing the optical parameter field of a diffuse medium based on a microlens array and a pulsed laser in this embodiment, the diffuse medium 3 refers to a medium that absorbs and scatters infrared light, so The dispersion medium 3 is one of biological tissue, flame or ceramics.

specific Embodiment approach 3

[0030] The reconstruction method of the optical parameter field of the diffuse medium based on the microlens array and the pulsed laser in this embodiment, the method is realized by the following steps,

[0031] Step 1, turn on the laser controller 1, make the pulsed laser light emitted by the laser head 2 shoot into the dispersion medium 3, and then guide the dispersion medium 3 to the center point of the first microlens array light field camera 4 and the third microlens array light field camera 6 The connecting line of the axis is rotated by 90°, so that the pulse laser acts on another boundary of the dispersive medium 3 until the four boundaries of the dispersive medium 3 are all subjected to the pulse laser emitted by the laser head 2 once;

[0032] Every time the laser head 2 emits a pulsed laser, it uses the first microlens array light field camera 4, the second microlens array light field camera 5, and the third microlens array light field camera 6 to transmit or reflect...

Abstract

The invention relates to a microlens array and pulse laser based dispersion medium optical parameter field reconstruction device and method, and belongs to the field of infracted optical imaging. A technical method measuring optical field signals via a microlens array lacks at present. In the reconstruction device, a data processing system (7) is connected with a laser controller (1) and three microlens array light field cameras, the laser controller (1) is connected with a laser head (2), and a dispersion medium (3) is arranged at the center of an area enclosed by the laser head (3) and the three microlens array light field cameras. The reconstruction method comprises measuring emitting radiation in the medium boundary, calculating transmission of near-infrared pulse laser in the dispersion medium and reconstructing an optical parameter field. According to the invention, the optical parameter field of the dispersion medium is reconstructed, and new technical means is provided for near infrared optical imaging and infrared detection.

Description

technical field [0001] The invention relates to a device and a technical method for measuring light field signals through a microlens array, in particular to a reconstruction device and a reconstruction method for a diffuse medium optical parameter field based on a microlens array and a pulsed laser. Background technique [0002] The reconstruction of the optical parameter field inside the dispersive medium is to invert the internal optical parameter field by analyzing the measurement signal at the boundary of the medium. Since the distribution of optical parameters inside the medium is related to the structure inside the medium, the reconstruction technology of the optical parameter field inside the dispersive medium is helpful. It is used to detect the internal geometry of the medium. As an effective detection technique, optical parameter field reconstruction of diffuse media is widely used in nondestructive detection, optical imaging, infrared remote sensing, information ...
