Title:
IMAGING METHOD, DEVICE AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/188442
Kind Code:
A1
Abstract:
An imaging method, for use in an optical detection system (100). The optical detection system (100) comprises an imaging device (102) and a bearing platform (103). The imaging device (102) comprises a lens module (104) and a focus module (106). The method comprises the following focusing steps: using the focus module (106) to emit light to a sample (300) on the bearing platform (103); moving the lens module (104) to a first setting position along an optical axis; moving the lens module (104) from the first setting position to the sample (300) in a first set step size along the optical axis, and determining whether the focus module (106) receives the light reflected from the sample (300) or not; if the focus module (106) receives the light reflected from the sample (300), moving the lens module (104) to the sample (300) in a second set step size, less than the first set step size, along the optical axis and calculating a first light intensity parameter according to the light intensity of the light received by the focus module (106), and determining whether the first light intensity parameter is less than a first set light intensity threshold or not; and if the first light intensity parameter is less than the first set light intensity threshold, storing the current position of the lens module (104) as a storage position. The imaging method is convenient to operate and can reduce cost.
