Abstract: A multimodal signal acquisition device and method, and a laser image system are provided. The multimodal signal acquisition device is configured to acquire a multimodal signal generated by a laser pulse that irradiates a sample and includes an independent-channel acquisition module and a spectral signal processing device. The independent-channel acquisition module is provided with multiple independent spectral signal acquisition channels, each of which corresponds to a spectral signal of a specific spectral range in the multimodal signal. Each of the spectral signal acquisition channels acquires the multimodal signal, filters the corresponding spectral signal of the specific spectral range from the multimodal signal, and sends the spectral signal to the spectral signal processing device. The spectral signal processing device is configured to receive the spectral signal acquired by each of the spectral signal acquisition channels and perform imaging and superposed output of each spectral signal.
