OPTICAL PICTORIAL STUDENTS FOR THE RECORDING OF TWO-DIMENSIONAL IMAGES IN THE NEAR INFRARED RANGE

摘要

An optical image sensor for taking two-dimensional images in the near infrared range, comprising a photocathode (2) having a photon (PH) entrance surface (6) with an electron exit surface (7) parallel to the entrance surface (6) a layer arrangement (8) which is arranged between the entry surface (6) and the exit surface (7) and which is configured such that the photon (PH) entering through the entry surface (6) exits the exit surface (7) of the electron (EL). causes, wherein an exit position (AP) of the electron (EL) at the exit surface (7) with an entry position (EP) of the photon (PH) at the entrance surface (6) corresponds; anda single photon avalanche photodiode device (9) comprising a single photon avalanche photodiode array (10) having a plurality of two-dimensionally arranged single photon avalanche photodiodes (11), the single photon avalanche photodiode device (11) 9) is arranged with respect to the photocathode (2) such that the electron (EL), after exiting the exit surface (7) of the photocathode (2), strikes the single-photon avalanche photodiode array (10) Impact position (AFP) of the electron (EL) on the single-photon avalanche photodiode array (10) by means of the plurality of two-dimensionally arranged single-photon avalanche photodiodes (11) is detectable, so as to generate an image signal (BS); optical image sensor (1) for receiving two-dimensional images in a wavelength range having wavelengths of at least 1.4 microns is formed.
