A wide-illuminance full-color imaging detection chip

Abstract

The invention discloses a wide-illuminance panchromatic imaging detection chip comprising an area array electronic-control dual-mode plane liquid crystal micro-lens, an area array panchromatic detector and a drive-control preprocessing module, wherein the area array panchromatic detector is divided into a plurality of array-distributed sub area array panchromatic detectors, each sub area array panchromatic detector comprises a plurality of array-distributed photosensitive elements with the same numbers and arrangement manners; the area array electronic-control dual-mode plane liquid crystal micro-lens is coupled with the area array panchromatic detector in a matching manner and comprises a plurality of array-distributed unit electronic-control dual-mode plane liquid crystal micro-lenses, and each unit electronic-control dual-mode plane liquid crystal micro-lens corresponds to one sub area array panchromatic detector; the area array electronic-control dual-mode plane liquid crystal micro-lens carries out oriented collection and dispersion on incident light or maintains the space transmission form of a light beam based on the intensity of the incident light. According to the wide-illuminance panchromatic imaging detection chip disclosed by the invention, the panchromatic image information in a wide illuminance range can be obtained, the measurement precision is high, the target and environment suitability is good, and the detection chip is easy to be coupled with a regular optical system.

Description

technical field

[0001] The invention belongs to the technical field of imaging detection, and more specifically relates to a wide-illuminance full-color imaging detection chip. Background technique

[0002] So far, panchromatic imaging devices based on the area-array focal plane photosensitive architecture have entered the family, and have become a basic means of image information acquisition in the fields of industrial and agricultural growth, teaching, scientific research, and national defense. For the core photosensitive array, whether it can continuously improve the ability to deal with strong light and low light targets in complex background environments has become an important source of power to promote the continuous and rapid development of arrayed photosensitive devices. So far, people have continuously developed photosensitive chips with larger and larger arrays, improved the photoelectric sensitivity of photosensitive materials, reduced photosensitive structural n...
