We examine the interplay between spectral bandwidth and illumination curvature in ptychography. By tailoring divergence of illumination, broader bandwidths can be tolerated without requiring algorithmic modifications to forward model. In particular, a strong wavefront transitions far-field diffreaction geometry an effectively near-field one, which is lees affected by temporal coherence effects....

Sappan wood (Caesalpinia sappan L.) is a plant that contains many phytochemical constituents such as antioxidant, antimicrobial, antifungal and antiacne have functional activities. woods several phenolic compounds brazilin, xanthone, flavones coumarin. In order to extract the compounds, Ultrasound-Assisted Extraction (UAE) considered green technology gives better quality products with higher ex...
