description The embodiment of the invention provides an imaging device and an imaging method, which relate to the technical field of laser imaging. The imaging device is configured to perform imaging processing on a to-be-tested article. The imaging device comprises a femtosecond laser device, a pulsed time domain broadening device, a filtering device and an imaging device, wherein the femtosecond laser device is used for emitting femtosecond pulses; the pulsed time domain broadening device is used for performing time domain broadening processing on the femtosecond pulses to generate chirped pulses and sending the chirped pulses to the to-be-tested article, and the time domain and the frequency domain of the chirped pulses are in one-to-one correspondence; the filtering device is used for filtering the chirped pulses passing through the to-be-tested article to generate multiple sub pulses carrying the information of the to-be-tested article, and the sub pulses are isolated in time and space; and the imaging device is use
