Embodiment Construction

[0021] Such as Figure 1-3 As shown, a single-photon camera based on a double-layer MCP image intensifier includes: a front cover 201, a double-layer MCP image intensifier 202, a fiber cone coupling lens 203, a detector 204, a timing control module 205, a gate control Module 206 , housing 207 and rear cover 208 . The double-layer MCP image intensifier 202 includes: a photocathode 101 , a double-layer microchannel plate 102 , and a fluorescent screen 103 .

[0022] in:

[0023] The double-layer MCP image intensifier 202 converts the weak light signal incident on its photocathode 101 into an electrical signal, and performs electron multiplication through the multi-stage amplification of the double-layer microchannel plate 102. -Optical signal conversion, and finally realize the gain and amplification of optical signal.

[0024] The fiber taper coupling lens 203 couples the amplified optical signal of the double-layer MCP image intensifier to the target surface of the detector...

Abstract

The invention discloses a working principle, system composition and a single photon counting principle of a single photon camera based on a double-layer MCP image intensifier. The single photon cameramainly comprises a double-layer MCP image intensifier, a fiber cone-coupled lens, a detector, a time sequence control module, a gate control module, a housing and a cover plate and the like. The single photon camera being a photo-electronic imaging device for low-light signal detection and imaging has the capability of single photon signal detection and is capable for realizing large-area singlephoton detection and thus has the great application value in fields of bio-fluorescence, medical imaging, astronomical observation, remote sensing telemetry, criminal exploration, military investigation and the like.

Description

Technical field: [0001] The invention relates to the field of low-light detection, in particular to a single-photon imaging camera for detecting single-photon signals and a realization method thereof. Background technique: [0002] Twilight refers to light that is so weak that the energy of the light is so low that it cannot cause the human eye or image sensor to respond in a low-light environment. Low-light imaging technology, through photoelectric conversion, high-performance amplification, transmission and processing, etc., enables human vision or image sensor devices to be effectively expanded in space, time domain and frequency domain, and converts high-quality and clear images that can be recognized by human eyes or image sensors. Image, thus making up for many problems such as low sensitivity, low resolution and poor color recognition ability of human eyes or image sensors in low-light environments, and provides a strong technical support for human beings to understan...
