A protection device used in a lensless imaging detection system and a lensless imaging detection system using the device

摘要

The invention relates to a protection device in a system for detecting objects of interest dispersed in a sample. The system comprises a light emitter (() 1) for emitting light in the main direction (× x).An image sensor (2) d '- a transparent visualization area (z) (...) for receiving a sample is located at the light source (...) and the sensor (2) (...)The sensor (2) is configured to obtain an image of the sample from the radiation transmitted by the radiation source through the visualization area of the radiation source, and the device includes a protection device between the light source (1) and the visualization area (z). Protect the visual area of the deposit.
