Lensless holographic microscopy for analysis of pollens relevant to veterinary medicine

Abstract

Pollen monitoring is helpful for medical purposes, weather or crop forecasting, and climate change analysis. Pollens are also important aeroallergens in veterinary medicine, causing atopic dermatitis in dogs and horses, and skin disease, seasonal rhinitis, and asthma in cats. In this study, we develop a lensless microscope and investigate its prospects for real-time detection and identification of six pollens relevant to veterinary medicine. By a systematic selection of a light source and imaging sensor, we present an optimal design for capturing digital holograms. Various light sources are studied based on parameters, including the source-object distance, temporal and spatial coherence, wavelength, and optical power for pulsed illumination. We propose an automated pollen detection and identification procedure based on a deep learning model for hologram classification. The proposed procedure is validated by an experienced pathologist using a conventional commercially available light microscope.
