The invention aims to provide a biological tissue detection system based on array fiber optics bundle illumination imaging with micro structure, convenient operation and high resolution. The detectionsystem comprises a laser, a lens, a spatial light modulator, a coupler, an optical fiber endoscope with an acoustic probe, an acoustic detection amplifier and a control processor, wherein a laser source generated by the laser is transformed into a parallel beam through the lens, the parallel beam is modulated by the spatial light modulator to form a speckle single, then the speckle single is coupled into the optical fiber endoscope through the coupler and projected onto a to-be-tested biological tissue by an optical fiber illumination head, an acoustic wave signal generated by the heat absorption of the biological tissue is received by the acoustic probe and amplified by the acoustic detection amplifier, and then is converted into an electrical single to betransmitted into the control processor, and according to the predetermined algorithm, the control processor can obtain the tissue distribution of the to-be-tested biological tissue based on the modulation matrix, the received electrical signal and the receiving time.
Description
Technical field [0001] The invention belongs to the technical field of biomedical imaging, and specifically relates to a biological tissue detection system based on array fiber beam illumination imaging with miniaturized structure, convenient operation and high resolution. Background technique [0002] With the rapid development of optical imaging technology, people's demand for information resources is increasing, and the main way to obtain information is optical imaging. Fiber optic technology is a new type of optical imaging technology that can image the cross-section of the internal structure of translucent objects. Compared with other traditional imaging technologies (such as X-ray, CT, ultrasound imaging, and MRI scan imaging), optical fiber technology has obvious advantages, and is particularly suitable for real-time non-destructive inspection and imaging of biological tissues. [0003] In recent years, visualization of medical devices has become a trend, and endoscopy tech...
