Controlling integrated energy of laser pulses in a fluorescence imaging system
By placing an image sensor at the distal end of the endoscope and using pulsed electromagnetic radiation and a PID control algorithm, a color image superimposed with fluorescence imaging data is generated, which solves the limitations of traditional endoscopes in imaging in low-light environments and improves image quality and system durability.

AI Technical Summary
Traditional endoscopes cannot simultaneously achieve color and fluorescence imaging in low-light environments, and their image sensors are easily damaged and cannot be adapted to the distal end of the endoscope, resulting in degraded image quality and expensive multi-system imaging requirements.
An image sensor is placed at the distal end of the endoscope to capture independent exposure frames through pulsed electromagnetic radiation of different wavelengths, generating a color image superimposed with fluorescence imaging data. A PID control algorithm is used to adjust the light source to ensure the exposure level, combined with a pixel array of variable colors and multi-wavelength fluorescence imaging.
It enables the simultaneous generation of color and fluorescence imaging data in low-light environments, improving image quality and sensor durability while reducing system complexity and cost.
