由Intevac公司的工程师研制的高效传输电子（TE）光电阴极是最近由公司论证的新型激光照明观察与测距系统（LIVAR）的心脏。因此，InGaAs光电探测器1．0到1．6urn的彼长范围量子效率达15％，比一般St阴极的灵敏度高几个数量级。同时新的探测器也适用于公司的1·sumLIVAR系统。
The high-efficiency transmission electron (TE) photocathode developed by Intevac’s engineers is the heart of the recently demonstrated LIVAR laser-based vision and ranging system (LIVAR). As a result, the long-range quantum efficiency of InGaAs photodetectors 1.0 to 1.6urn is 15%, which is several orders of magnitude greater than the sensitivity of a typical St cathode. At the same time the new detector also applies to the company’s 1 · sumLIVAR system.
