An imaging device capable of improving resolution, its imaging method and detection equipment

Abstract

The invention discloses an imaging device capable of improving resolution, an imaging method and detection equipment. Wherein, the imaging device includes: a transmitting end, including a plurality of light emitters, for illuminating a set area; a processing module, for controlling the working sequence of each light emitter, and making at least one light emitter work each time; a light splitting module, It is used to perform spectroscopic processing on the light emitted by the light transmitter, so that it irradiates the set area in an array manner; the receiving end is used to receive the reflected light of the target object in the set area, and generate light according to the exposure area. Image; the processing module is also used to acquire the image and distance of the target object according to the image and light travel time. In the present invention, the transmitting end transmits optical signals in different time periods, and modulated by the optical splitting module to make the optical signals irradiate the set area of ​​the target object in an array manner, so that the receiving end can be exposed in partitions to realize depth imaging and distance measurement, thereby improving the image quality. resolution.

Description

technical field [0001] The invention relates to photoelectric detection technology, in particular to an imaging device capable of improving resolution, an imaging method and detection equipment. Background technique [0002] Time-of-flight (TOF) technology is a ranging technology that measures the distance of the target object in a specific scene. By continuously sending light pulses to the target object, the sensor receives the light reflected from the target object, and detects the distance of the light pulse. Flight (round trip) time to get target object distance. [0003] In this technology, a single photon detector (SPAD, Single Photon Avalanche Diode) has a great potential application scenario, and its usage scenarios are as follows figure 1 As shown, the laser pulse signal is first emitted by the laser transmitter, the signal is reflected by the target object and then received by the depth sensor, and the time between the signal from the transmitter to the receiver i...
