Abstract

The invention discloses a device and method for detecting the quality of a focused light spot of a mini-type self-focusing lens. The device comprises a light source, an optical fiber jumper wire, a five-dimensional adjusting frame, a mini-type self-focusing lens clamp, a microscopy system, a light beam analysis meter and a computer. The computer and the light beam analysis meter are operated, light beams output by a light source pass through the optical fiber jumper wire, the mini-type self-focusing lens and the microscopy system in sequence and are transmitted to the light beam analysis meter, and the form center position and the light spot size information, detected by the light beam analysis meter, of the light beams are displayed and recorded in the computer. According to the device and method, rapid and accurate detection of the quality of the focused light spot of the mini-type self-focusing lens can be achieved and the focal length of the mini-type self-focusing lens can be indirectly measured.

Description

technical field [0001] The invention relates to the technical field of light beam quality analysis, in particular to a method for detecting the quality of a focused light spot required for the detection of the focusing performance of a micro self-focusing lens. Background technique [0002] Gradient index lens (GRIN Lens) or self-focusing lens (self-focusing lens), because its end face is flat, it is easy to glue directly with other optical elements, and has broad application prospects in biomedical and surgical diagnosis. It has unique advantages in the development of miniaturized probes for Optical Coherence Tomography (OCT), a medical imaging technology. The probe is a key component of the OCT system, and its focusing performance has an important impact on the imaging quality of the OCT system. For example, the focus position and focus spot size of the light source beam after passing through the probe greatly affect the detection depth and imaging lateral direction of the...
