In the last decade, terahertz-mode imaging has received increased attention for non-destructive testing applications due to its ability to penetrate many materials while maintaining a small wavelength. This paper describes a model-based reconstruction algorithm that is able to image defects in the spray-on foam insulation (SOFI) used in aerospace applications that has been sprayed on a reflecti...

Purpose To determine whether dopamine receptor D1 (D1R) signaling pathway activation by bright light (BL) in specific retinal neuronal cell types contributes to inhibiting form-deprivation myopia (FDM) in mice. Methods Mice (3-weeks old) were raised under either normal light (NL: 100-200 lux) or BL (2500-5000 lux) conditions with or without form deprivation. Refraction changes were evaluated ...

PURPOSE To measure the peripapillary retinal nerve fiber layer (RNFL) thickness in normal Indian pediatric population. SUBJECTS AND METHODS 120 normal Indian children ages 5-17 years presenting to the Pediatric Clinic were included in this observational cross-sectional study. RNFL thickness was measured with stratus optical coherence tomography (OCT). Children with strabismus or amblyopia, wi...

PURPOSE To assess wavefront derived refraction and full eye biometry including ciliary muscle dimension and full eye axial geometry in pseudophakic eyes using spectral domain OCT equipped with a Shack-Hartmann wavefront sensor. METHODS Twenty-eight adult subjects (32 pseudophakic eyes) having recently undergone cataract surgery were enrolled in this study. A custom system combining two optica...

We have developed an integrated method to obtain highresolution subsurface elastic parameters using combined wave equation tomography (WET) and full waveform inversion (FWI). Both refraction and reflection data are used. During parameterization, long wavelength and short wavelength structures are separated and mapped into velocity and density to account for kinematics and dynamics, respectively...

The aim of this study was to analyze and compare corneal biomechanics in patients with bilateral keratoconus (KCN) with unilateral Vogt's striae. In this prospective contralateral study, visual acuity, refraction, and corneal biomechanical parameters were evaluated in patients with bilateral KCN with unilateral Vogt's striae using the Ocular Response Analyzer (ORA) (Reichert Inc., Buffalo, NY) ...
