Optical detection system and laser light providing module without using an optical fiber

An optical detection system, comprising:

• a carrier module configured for carrying a plurality of photodiodes;
• a laser light providing module configured to be disposed above the carrier module;
• an electrical detection module configured to be disposed adjacent to the carrier module;
• and
• an image capturing module configured to be disposed above the carrier module;
• wherein the laser light providing module includes a laser chip package structure without using an optical fiber, a first optical lens adjacent to the laser chip package structure, and a beam quantity adjuster adjacent to the first optical lens;
• wherein the laser chip package structure is configured for generating a laser light source projected onto the first optical lens, and the first optical lens is configured for converting the laser light source into a laser beam projected onto the beam quantity adjuster, and the beam quantity adjuster is configured for splitting the laser beam into a plurality of projection beams;
• wherein, when the projection beams are simultaneously and correspondingly projected onto the photodiodes, the image capturing module is configured for capturing position information of a light spot projected by the projection beam on an active region of a corresponding one of the photodiodes;
• wherein, when each of the photodiodes is excited by a corresponding one of the projection beams to correspondingly generate an electrical signal, the electrical detection module is configured for simultaneously and electrically contacting the photodiodes so as to sequentially obtain the electrical signals that are correspondingly generated by the photodiodes.
