Thermal Imaging Cameras Monitor The Quality Of Vessel Constructions
 
By FLIR Systems, Inc.

Shipbuilding requires advanced, nondestructive testing methods to ensure the quality of the ship's construction, and therefore the quality of the fleet. This article describes how thermal imaging is used for things like vessel construction, surface inspection, detection of undercoat corrosion, quality control, and more.

Spotlight On LIDAR/LADAR
Avalanche Photodiodes For LIDAR Applications

Avalanche photodiodes (APD) are ideal for laser-based distance measurement, laser scanning and mapping, shape recognition and remote sensing, as well as LIDAR (Light Detection and Ranging). APDs also excel in applications with very low optical signal strength or with high modulation frequencies.

Precision Optical Solutions — Custom And Commercial

PG&O provides complete, in-house turnkey optics solutions, including precision optics and commercial components, thin film coatings, complete fabrication services, and an extensive in-house glass inventory. PG&O is also an expert at fabrication and assembled optics.

Silicon Avalanche Photodiode (APD) Arrays

LASER COMPONENTS offers silicon avalanche photodiode (Si ADP) arrays for applications in LIDAR and ACC within the 800 to 900 nm wavelength range. The SAH series of Si APD arrays are typically used in Time-of-Flight (TOF) sensors for distance measurements, such as in automotive sensing applications.

Fiber Optics

The line of active and passive fiber optic components and modules from Gooch & Housego provide the performance and reliability needed for a variety of applications including space, terrestrial, and submarine telecommunications systems. 

LIDAR Guns, Accuracy, And Speeding Tickets

A Light Detection and Ranging (LIDAR) system uses a 130 μW, 904 nm beam produced by three light emitting diodes (LEDs), and a telescope working together in order to calculate how long it takes for the beam to leave the device and return to the telescope.

Technical Note: Guide To Glass

Abrisa Technologies’ "Guide to Glass" provides information about the types of glass and their associated thermal, optical, chemical, mechanical, and electrical properties; understanding light and color; glare reduction; and glass strengthening methods using heat and chemicals.

Contact Lens Metrology With The 157 Series Optical Thickness Gauge

Bristol Instruments’ 157 Series optical thickness gauge is ideal for contact lens metrology. Its guaranteed performance over long periods of time and its ability to measure absolute thickness to an accuracy of +0.1 µm and repeatability as high as +0.05 µm make it an ideal solution for this application.

Theory And Measurement Of The Modulation Transfer Function (MTF)

MTF is a quantitative and objective measure of the quality of an image formed by a lens or an electro-optical system. This measurement is appropriate for lenses of all qualities and can be calculated from lens design data, which enables theoretical and actual performances to be compared.
