We characterize a 1/spl times/32 element metal-semiconductor-metal photodetector (MSM-PD) array utilized for optoelectronic mixing in an incoherent, amplitude-modulated laser detection and ranging (LADAR) system. The MSM-PDs that make up the one-dime

Translational Doppler detection using a direct-detect, chirped, amplitude-modulated LADAR is demonstrated. A nonoptically coherent system is utilized to lower the target-induced Doppler shift to tens of Hz, as opposed to several hundreds of megahertz

The optoelectronic mixing effect in InAlAs Schottky-enhanced InGaAs-based metal-semiconductor-metal photodetectors (MSM-PDs) is analyzed. The measured frequency bandwidth of the optoelectronic mixer (OEM) is less than that of a corresponding photodet

Recent experiments show that variation in rectification current with ac-bias frequency exists in metal-semiconductor-metal (MSM) detectors. In this letter, we theoretically study the frequency-dependent rectification current in MSM detectors. Under t

The Long Wave Infrared (LWIR) Profile Feature Extractor (PFx) sensor has evolved from the initial profiling sensor that was developed by the University of Memphis (Near IR) and the Army Research Laboratory (visible). This paper presents the initial s

The optical performance of an infrared sparse sensor detector system is modeled. Such a system, due to its low cost, uses single element, spherical, off-the-shelf optical components that may produce poor quality off-axis images. Since sensors will no

The Army Research Laboratory (ARL) has developed a three dimensional (3D) imaging ladar based on an amplitude modulated laser for which the frequency of the amplitude modulation (AM) is linearly increased and/or decreased with time (i.e., chirped). T
