Embodiment Construction
[0052] In order to make the technical means, creative features, work flow, and use methods of the present invention achieve the purpose and effect easily understood, the present invention will be further described below in conjunction with specific embodiments.
[0053] Description of the structure of the integrated photodetector module: This module consists of:
[0054] A scanning "sensor assembly" that contains:
[0055] A 32-pixel linear array (or single-pixel) long-wave infrared detector chip, a multi-core parallel laser diode bar with an output wavelength of 808nm and a PIN diode integrated on the ceramic substrate, positioned and installed in a sealed 2 optical lenses on the housing: including a germanium lens with a diameter of 9mm and a LD collimator lens with a diameter of 3mm (a cylindrical lens is also integrated above the LD to pre-adjust the laser divergence angles of the LD fast axis and slow axis to be consistent) .
[0056] A wide dynamic and high-sensitivity...

A comprehensive photoelectric detection system comprises a scanning 'sensor assembly'. A long wave infrared detector chip of a 32-pixel linear array (or a single pixel), a multi-core parallel connection laser diode bar, a PIN diode and two optical lenses are integrated on a ceramic substrate inside the scanning 'sensor assembly', the output wave length of the multi-core parallel connection laser diode bar is 808nm, the optical lenses are located and arranged on a seal shell body and used for preliminarily adjusting the laser divergence angle of an LED fast axis and the laser divergence angle of a slow axis to be in conformity, and the scanning 'sensor assembly' achieves scanning in front of a vehicle head through a horizontal scanning mirror. The scanning mirror is formed by a glass base reflector, a light alloy suspension bracket, two bearings, a drive device and a corner feedback and shifting sensor, wherein the glass base reflector is provided with a broad band reflective film and a protective antireflection film in an evaporation mode. The comprehensive photoelectric detection system is abundant and complete in information acquisition and simple in structure.
Description
technical field [0001] The invention relates to auto parts, in particular to a comprehensive photoelectric detection system. Background technique [0002] At present, there are no more than three solutions used in the field of automotive night vision at home and abroad, two of which are based on CCD / CMOS near-infrared / visible light imaging devices, and the other is based on UFPA (uncooled long-wave infrared focal plane device). Among them, based on CCD / CMOS near-infrared / visible light imager, it can be divided into active type and passive type according to whether near-infrared light source is used. [0003] Most of the car night vision solutions proposed in China are passive solutions based on the so-called "high-sensitivity" camera. Due to the limitation of the dynamic range and night vision performance of the device itself, the effective detection distance at night is almost the same as that of the human eye. , so these systems are moot. [0004] At present, the solutio...
