A Redesign and Enhancement of the Low Light Auto-Radiometer (LoLAR) for Deep-Sea Irradiance Measurements.

P.I. Widder, Edith （Harbor Branch Oceanographic institute）提案号：0221097 PIs建议升级低光自动辐射计（LoLAR）。LoLAR是一种潜水式辐射校准探测器，由NSF和ONR联合资助开发。它目前部署在Johnson- Sea-Link潜水器上，下潜至1000米深处，测量与中远洋生物垂直分布和迁移模式有关的下游辐照度，并进行生物发光的原位测量。LoLAR结合了光电倍增管的高量子效率和固态自动校准电路。所要求的资金将用于根据经过验证的自动校准概念重新设计LoLAR，利用最近的技术发展，可以大大降低系统的成本、尺寸和复杂性，目的是开发一种多功能仪器，可以为更广泛的用户提供服务。

P.I. Widder, Edith (Harbor Branch Oceanographic Inst.) Proposal #: 0221097The PIs propose to upgrade the Low Light Auto-Radiometer (LoLAR). LoLAR is a submersible, radiometrically calibrated detector that was developed with joint funding from NSF and ONR. It is currently deployed on the Johnson- Sea-Link submersible, down to depths of 1000 m to measure downwelling irradiance with respect to the vertical distribution and migration patterns of mesopelagic organisms, as well as to make in situ measurements of bioluminescence. LoLAR combines the high quantum efficiency of a photomultiplier tube with a solid-state autocalibration circuit. The funds requested would be used to redesign LoLAR based on a proven auto-calibration concept, using recent technological developments that make it possible to greatly reduce the cost, size, and complexity of the system with the intent of developing a versatile instrument that can be made accessible to a wider range of users.
